From DUNU
LUNA is the world's first pure beryllium rolled foil diaphragm flagship dynamic in-ear. As our flagship product, LUNA was tuned to a reference sound signature --- deep and natural imaging, even and smooth from top to bottom, and maximized for extension at both ends. The result is the most supremely detailed, transparent, sumptuous sounding earpiece ever crafted by DUNU. It is our best representative of beryllium’s full sonic potential, and we are absolutely thrilled to have everyone experience LUNA.

We partnered with Hangzhou-based designer and long-time audiophile Moses Xu and his team at Zinc Studio & Audio Salon for the industrial design.

LUNA is a story within itself, reflecting the spirit of the first moon landing 50 years ago, and elevating the manner in which in-ear monitors are perceived.

「玥」is the representative Chinese character for the LUNA, signifies a heavenly, pearlescent gift from the gods. From this luminous, round canvas, Xu worked to elevate every design element for the LUNA, blending them seamlessly with an overarching moon landing theme.

Heavenly Pearl

LUNA’s circular, concave faceplate serves as a physical representation for the changing albedo of the moon across each moon phase, while the asymmetric lip delineates waxing and waning crescentic shapes.

The outer facet of LUNA’s CNC body of custom-formed titanium alloy is sandblasted to reflect subtle specular highlights, just as the craterous central concavity draws in a penumbra of shadow.

The inner facet of the body preserves distinct lines created by the machining process, creating natural contour lines much like a topographic map. Functionally, the concave recess and slanted lip allow LUNA to be inserted and removed comfortably.

Man & Moon

Whereas the body of the LUNA is contoured, the beveled edges of the cable connector interface represent a more technical facet to the moon theme --- an abstract representation of the Apollo spacecraft.

Transitioning from man-made starkness to celestial fluidity, the smooth, domed end cap serves as a point of transition from human engineering to planetary body.

From the side, with cables attached, one can make out the profile of an orbital path taken to the moon. Finally, when turned on its side, custom-made blue silicone tips serve as a reminder of Earth as seen from the Moon.

Titanium Housing

LUNA's housings are precision machined entirely from a custom-modified grade 5 titanium alloy.

Known for its structural integrity, grade 5 titanium alloy, also known as Ti-6Al-4V and TC4, is notable for its prevalent, workhorse-type use in aerospace and other industries where the strength of titanium is its highly important.

But we reformulated this alloy with a custom-modified composition of rare earth metals to minimize the ringing properties of titanium. Doing so allowed DUNU to bring out the natural, ‘colorless’ timbre of its one-of-a-kind driver.

Machined Topography

The inner facet of the housing bodies preserves distinct lines created by the machining process, creating natural contour lines much like a topographic map.

The moon is packed with copious amounts of precious Titanium ore, and these contours delineate a denuded surface landscape that defines LUNA.

Structural Integrity

Every component of LUNA's housings has been carefully considered, to maximize structural rigidity and to minimize cavitary resonances.

Our parts tolerances have been shrunken down to the smallest possible to ensure that its components, like those in a moonfaring spacecraft, are securely sequestered from the environment.

Genuine Beryllium

The acoustic grade rolled foil beryllium at the heart of LUNA's 10 millimeter speaker module is sourced from Materion Corporation (née Brush Wellman Electrofusion), the world's foremost extractor and processor of beryllium metals.

Beryllium is believed to be the ideal speaker material. An extremely high stiffness-to-mass ratio (high Young's modulus, low density) allows beryllium to possess a very high speed of sound at over 12,000 meters per second, around two and a half times faster than other commonly used cone/diaphragm materials like aluminum.

The very low Poisson's ratio of beryllium potentiates its ability to maintain pistonic motion of the driver, even at the edges of a diaphragm, and in turn preserves the imaging properties of the music being reproduced. The very high Debye temperature of beryllium also means the lattice structure of the beryllium metal is retained even at very high frequencies, translating to remarkable treble evenness. All these unique properties of beryllium enable audio designers to gain extra octaves of clean, non-distorting, non-ringing, high-resolution sonic output at both ends of the sonic spectrum.

Suspension and Mounting

A one-of-a-kind diaphragm material begets an one-of-a-kind driver design. The major engineering hurdle DUNU had to overcome during the development of the LUNA was the process of getting the rolled foil beryllium diaphragm to be bonded circumferentially to a very thin polyurethane suspension.

Doing so required formulating bespoke glues, lightweight and thin enough so as not to impact the total weight of the acoustic system, and reliable enough to be glued evenly against a very thin lip and still confer enough durability to sustain the immense mechanical energy delivered during driver excursion.

Absolute Control

To harness and control the motion of the beryllium foil, LUNA's N52 Neodymium magnetic system was custom-ordered to impart much higher magnetic flux across the European-imported CCAW voice coil, especially when compared to conventional magnet systems.

Engineered Reference

To prove our driver design, we carried out high-speed vibrometry of LUNA's pure beryllium foil driver at a third party site.

With fully preserved pistonic motion across the entire driver, it only made sense that LUNA was tuned to a reference sound signature --- deep and natural imaging, even and smooth from top to bottom, and maximized for extension at both ends.

The result is the most supremely detailed, transparent, sumptuous sounding earpiece ever crafted by DUNU, and our best representative of beryllium’s full sonic potential.

From Burson Audio
Some DAC/Amps claim to give you the front row experience in exchange for less soundstage. Others promise a 3D soundstage in trade for fewer details. The Conductor simply gives you everything in the recording, without sugar-coating, the good and sometimes the ugly. You can locate a tapping foot on the stage while enjoying that lingering vibration of air after a keystroke.

Advanced Digital

The Conductor uses the SABRE32/ESS9038Q2M DAC and XMOS USB receiver chips, the most advanced and expensive in the industry. Its Customised USB driver by Thesycon Germany ensures low latency bit-perfect audio playback. The result is incredible processing power, accurately playing back DSD512 and 38bit/786khz audio.

It also features a Qualcomm/CSR8675 Bluetooth 5.0 receiver. Playing back at 24bit/96khz with aptX HD audio codec. , it pushes sound quality and ease of use to the highest level.

Max Current Power Supply

The Conductor Performance features the same Max Current Power Supply (MCPS) that has made the Conductor Reference legendary.A technology developed, owned and used exclusively by Burson Audio, the MCPS raises voltage frequency from 50Hz to 170kHz, pushing noise beyond human hearing. It completely overcomings the disadvantages of both linear power supplies and conventional switching power supplies, resulting in incredible dynamic and micro-details.

The Cool Case

We like to turn Class-A amplifiers from monsters with heat-fins into elegant, desktop-friendly machines, and we do it through the Cool Case. Made from high-density aluminum and electroplated to space-grey, the Cool Case is a unified heat-sink keeping the Class-A Conductor cool and optimized. Critics such as Headfonics called it “the new standard” in the audio industry.

Having a footprint that is 30% less than the Conductor Reference and a volume similar to a lunch box, it is beautiful but unobstructive. Take it to work, and no one will raise an eyebrow.

Opamp Rolling Fun

The Conductor Performance comes with Burson V6 Vivid discrete opamps. But don’t let us or anyone dictate your listening experience. The Conductor encourages opamp rolling with gold plated DIP8 sockets along its signal path. With hundreds of audio opamps out there, you have the freedom to tailor your listening experience to your preference.

The Sound

While our Conductor Reference is like Huge Jackman in Kate and Leopold, the completed package, the Conductor Performance is the shredded Wolverine. It’s still him but stripped down! Power and total control of that power will be the overwhelming first impression. It energises every note and space in between, bringing accuracy and micro-details. The C3 performance is for the perfectionist who works hard and plays harder.

From Final
Sound design with consideration to the relationship between spatial impression and dynamic range of music, and physical characteristics of earphones and headphones.  Clarity of vocals and each musical instrument is extremely high, overwhelming presence and feeling of liveliness as if standing in the center of a live stage.
Sound design has been undertaken with consideration to the relationship between the spatial impression and dynamic range of music, and the physical characteristics of earphones and headphones.

Through research into the relationship between spaciousness, clarity and dynamic range of musical recordings, and the physical characteristics of earphones and headphones, we have learned that deeper enjoyment of music can be achieved through the target curves and driver design well suited to the sound design of music recordings.

B1 is a model designed with particular emphasis on proximity of sound and sense of reality. In music represented by animation soundtracks, recordings make the proximity of sound more conspicuous. For this type of music recording, the B1 has been designed to achieve playback more consistent with the balance of sound as created by the engineer.

Construction and Fit

The front-rear two-piece separable construction makes the product easy to repair for a lifetime of use.

Metal injection molding is a process by which powdered metal is mixed with a binder to form a resin in the desired shape and applying high-temperature sintering to achieve the desired form.

There is a high degree of freedom in molding the resin into the same shape as the cast, making it possible to achieve a complex internal design even with metal.

Superior feeling of fit of an earphone is determined by the presence or lack of a feeling of pressure. There are products on the market with an ergonomically praised organically curved surface that should be suitable for placement somewhere in the ear, but because the holding positions for those shapes place pressure on the ear, fatigue accumulates over time.

BA+Dynamic Driver Unit

Employs a total of 2 drivers: 1 Balanced Armature (BA) driver for high range sound and 1 Dynamic Driver for bass. There is no parsing of the frequency range by a network.

MMCX Connector＆Original high purity OFC silver coated cable

The MMCX connector was developed in-company. We've used high-purity OFC silver coated cables that provide a wide sound stage. These jointly-developed cables were originally designed by and are currently manufactured by the well-renowned Junkosha corporation for the purpose of being used with the supercomputer "Kei" due to their fast signal transmission speed. The insulator film is made from PFA which was also developed by Junkosha who used their extensive know-how through the JUNFLON® brand to create the ultimate in low-permittivity material. The outer tube is made from PVC for maximum flexibility. The user will experience surprising flexibility that both makes the cable extremely easy to use as well as reducing the likelihood of microphonics. In addition, the MMCX plug and the 3.5 mm mini-plug have a tendency to disconnect so we've far exceeded the regular QA pass criteria of a 5,000-time bend test by changing the connection design to one that can withstand more than 50,000 bends.

Original earpieces with a color difference between the left and right bushes.
Two types of silicon differing in rigidity are employed for the sound conduit and for the earbud that comes into contact with the user’s ear. The silicon used for the sound conduit is more rigid than that used for the earbud, and by having groove processing applied to it, combines both strength and flexibility. Soft silicon has been employed for the earbud, making for a comfortable fit and a high level of sound insulation.

One of the bushes is gray, while the other is red; by pulling the earpiece back slightly to check the color of the bush, it is easy to distinguish between left and right, even in places with subdued lighting. Since the bush colors of neighboring sizes are different (the gray bushes alternate between dark and light gray; the red bushes alternate between red and pink), it is also easy to distinguish between sizes.

The B2 is a model particularly well suited to rich spatial recordings. It is well suited to classical music recordings that take adequate advantage of the reflections and reverberation of a concert hall as well as live recordings to reproduce the feeling of "being there". Moreover, the B2 employs an MMCX connector that makes it possible to switch cables in the event of a severed connection.

From HEDD
HEDD is proud to introduce the first full range Air Motion Transformer headphones to audiophiles and recording artists worldwide. The Air Motion Transformer (AMT) is an electrodynamic transducer that allows to move air significantly faster than common voice coil, magnetostatic (planar) or electrostatic systems. Their traditional piston-like movement is overcome by a folded diaphragm that squeezes out air four times faster: A breakthrough for capturing more details in a musical recording.

30 years ago HEDD CEO and Chief Engineer Klaus Heinz designed the first compact and marketable AMT tweeter based on Oskar Heil’s original Air Motion Transformer invention. Since then he has increased its sonic quality in several fundamental revisions. The 2019 version of the AMT can be heard in HEDD´s innovative Series ONE studio monitor line.

Recently Heinz has focused on developing a full range Air Motion Transformer to break new grounds for this superior transducer principle. In order to reproduce the complete audible frequency band (and beyond), the HEDDphone® incorporates VVT® (pat. pending). VVT® introduces a new diaphragm geometry that expands the AMT principle to a linear full range (10Hz–40kHz) headphone transducer. It replaces the fixed geometric structure of conventional AMT drivers as the folds vary both in width and depth.

The HEDDphone® introduces a fourth transducer technology. It brings the enormous dynamic capabilities and the superior sonic resolution of the AMT principle to the world of top-end headphones. HEDDphone® excels where it really matters: in accurate, untamed, and touching music reproduction.

• Concept: open over-ear headphone with Air Motion

From Auris
All-in-one amp that encompasses three key functions: a pure tube Headphone Amplifier, Preamp and a DAC. Also acts like a headphone stand. Allows you to choose between low/high impedance and customize it to your headphones. Elegant design, with a wooden housing, takes little space on the rack.

Multi-functional
All-in-one amp can be used in many ways. Since it is multi-functional it can work like a headphone amplifier, pre-amplifier, and/or DAC. Euterpe can work with its own integrated DAC, or you can connect it with another DAC. Also, its pre-out function can be used in case you want to connect it to a smaller system at your home.

Headphone Stand
The possibility to be used like a headphone stand makes Euterpe strangely utilitarian for such a high-end piece of hardware. Your headphones fit right on top, with a shallow saddle cut into the wood, to keep the cans in place. It can take a full-size headphone.

Internal DAC
DAC inside can play modern sources. OTG input capability has some baseline specifics, including a decoding capability of up to DSD128, PCM max 32bit/384kHz. An XMOS USB DAC and ESS Sabre chipset represent the brain of Euterpe. The DAC quality is impressive with beautiful details captured.

Amplifier
Euterpe is a single-ended headphone amplifier with unbalanced circuit design, so there are no balanced inputs or outputs. The lineup of tubes is classic Auris, with the use of two 7-pin Ei PL95 tubes, which are the equivalent to 6DL5, and a single ECC81 input tube, also known like 12AT7 (running in Ultra-Linear mode). The output power is just a shade lower at 0.9W into a 32Ω load. The magic of Euterpe is really when it is connected to a high-end DAC which tells you a lot about how good that amp can be inside that beautifully crafted wooden enclosure.

Impedance Selector
To make your headphones shine in the best possible way, we make sure Euterpe has impedance swich marked with L/H (low/high) The inference here is a wider range and simpler switching design at 32-80 Ohm and anything greater than 150 Ohm. With the majority of planar headphones, they tend to rate less than 80 Ohm and are more impedance agnostic than dynamic headphones. You need to have that switch set to low or L.

Linear PSU
Euterpe power supply is an external regulated linear power supply, with a switchable 115/230 VAC capable output, and will keep noise to the minimum. It uses a fairly stiff but sturdy 4-pin connector 1m cable, so you can place the two units pretty far apart.

Technology
The Euterpe comes with the technology one would expect from an Auris Audio amplifier:

• It is composed of an xmos chip that handles USP input duties, a Sabre ES9018 chip handles the conversion duties, a 12AT7 tube handles pre-amp functions, with a Mundorf capacitor in line between the preamp and power tubes.
• The supplied power tubes are NOS (new old stock), branded Ei and stamped Yugoslavia: a single ECC81, dual-triode tube serves as the Euterpe’s input stage, while a separate PL95 pentode power tube is provided for each channel; these feed the output transformers. A selector set allows you to use the PL95s, as EL95s with a lower voltage.
• The power supply has a captive five-pin cable that connects to the amp, and a 15-amp IEC connector for a standard grounded AC power cord.

Use
Euterpe allows you to use digital sources such as PC or mobile device. For such an exotic piece of gear, the Euterpe is a piece of cake to use. There’s a master power switch on the power supply, but the main switch is built into the volume control. Just turn it fully counterclockwise to turn the power off. It’s as plug and play as a tube headphone amp gets.

Design
The Euterpe offers a bespoke exterior with the DAC and amp innards sandwiched between two pieces of solid wood. All of this sits on a beveled metal base. On any desk, the Euterpe looks classy, dignified, and inviting. It’s the kind of equipment you just can’t wait to fiddle around with. The tubes are aligned centrally at the top of the matte black aluminum housing with good separation between the top and sides of the wooden enclosure. They seem well protected from bumps, knocks and accidental finger touching.

Footprint
The Euterpe takes up little space on the rack. The overall dimensions of the Euterpe are 270mm (tall) x 210mm (wide) x 230mm (deep). Considering it doubles as a headphone stand you will need 5-10 cm more space to accommodate the additional height from a headphone headband.

According to the Greek Mythology, Euterpe was one of the nine Muses, the Goddess of music and a "giver of delight" and that's exactly what Auris Audio Euterpe will bring to the audiophile community – more happiness.

From Final
Final’s flagship model realizes transparent sound for the uplift that can be gained by listening to music. Development of the A8000 began with reconstruction of physical measurement and subjective evaluation methodologies. Under the subjective evaluation methodology established at the time of D8000's development, the E Series achieved sound quality highly evaluated by many people and became a best seller. With the A8000, a new evaluation index has been incorporated into that subjective evaluation methodology. 

Among factors that determine sound quality for earphones and headphones, amplitude frequency response is predominant, but there are some sound impression cannot be explained by it. For example, the most critically evaluated aspect of classical music recordings is called transparent sound, a sound impression by which sound is very clear even it is localized at a distant location. We have been considering the realization of this sound impression to be extremely important for becoming uplifted by listening to music. We believe that the high evaluation of our D8000 headphones owes to the realization of such transparent sound. Until now, we have employed modification of the amplitude frequency response, known as tuning, to modify the sound of our earphones, but because it cannot make a great change to time response, it became difficult to achieve transparent sound through tuning.

This time, with the aim of achieving transparent sound for earphones, final has developed its own proprietary Perceptual Transparency Measurement (PTM) evaluation methodology. As a result of evaluation and improvement of interrelations between principal components analyzed by the results of subjective evaluation and data analysis of impulse response that could not be gleaned from frequency response in the past, an ideal diaphragm material that is extremely light and possessing high sound speed comprised of ultra-thin Beryllium foil (Truly Pure Beryllium Diaphragm) has been adopted for the A8000.

Adoption of Truly Pure Beryllium Diaphragm
The A8000 employs a diaphragm made from ultra-thin Beryllium foil (Truly Pure Beryllium Diaphragm), which is said to be an ideal diaphragm material due to its light weight and high sound speed. With a specific gravity of 1.85 and a sound propagation velocity of 12,900 m/s, second only to that of diamond, Beryllium has ideal characteristics for a diaphragm material. The adoption of pure Beryllium will lead to improved time response that greatly transfigures sound into transparent. The sharpness of sound build-up and the lingering resonance of the sound can be clearly felt, as can the silence between sounds.

Crafting thin pure Beryllium foil is difficult. Our engineers had to struggle to make it stable enough for the product, but it can be said to be a valuable material that pays off our hard works. In order to realize transparent sound through such superior materials, the same high quality has been demanded of the other components of the drive unit as well as the design and manufacturing technology. We have succeeded in leveraging the experience of developing and manufacturing our own dynamic drive unit to draw forth the advantages of pure Beryllium.

In the past, a Beryllium diaphragm was created by vacuum deposition of a thin coat of Beryllium onto a resin film. This was effective as an improvement methodology, but the characteristics of the film remain predominant. When pure Beryllium is used as the only material for the sound producing part of the diaphragm, the sound and characteristics are completely different.

Balancing Getting an Uplift from a Wide Range of Musical Genres with Universally Good Sound

Sound design for these models has been undertaken with attention to the relationship between spatial impression and dynamic range of music, and the physical characteristics of earphones and headphones. We have categorized sound creation on music recording onto these two axes: spatial impression and dynamic range.

One way of thinking regards the distance perception. Classical and jazz recordings are thought to be performed with emphasis on aspects of spaciousness, such as sense of distance, broadness and reverberation. On the other hand, rock, pops and many of the recent animation soundtrack recordings, spaciousness is not as highly emphasized. There is thought to be greater emphasis on clarity, which brings the various instruments and vocals to the front.

Another approach is dynamic range - in other words, changes in loudness over time. If the dynamic range is wide, naturally it is possible to use the change in loudness over time to achieve a more dynamic expression of music. But, there are some types of music for which narrower dynamic range recordings are preferable to allow each of the instruments and vocals to ordinarily appear before the listener’s eyes.

The difference between these two ways of thinking pertains not to which is superior but rather differences in how music is composed and what is demanded of it. With regard to classical music, and that played by orchestra in particular, the spatial orientation of instruments is particularly important. Stringed instruments are positioned nearest to the audience with wind and percussion placed behind them. Should the balance between the spatial orientation and volume of each group of instruments collapse, the music would disintegrate. For that reason, uniform clarity of sound that allows each instrument to appear before the eyes of the listener is not demanded of this type of music. Even for classical music, a string quartet, for example, would have a narrow dynamic range and the clarity of each instrument would be more prominent. For rock and pops on the other hand, spaciousness is not as necessary as for classical music, and so there is greater emphasis on clarity than spaciousness.

These preconditions are very important, particularly for earphone and headphone listening, and it has become apparent that the implementation of appropriate target curves and driver design result in deeper enjoyment of music.

The superior time response of the A8000 imparts it with sound quality that is capable of providing an uplift from a wide range of music that approaches the extent of the D Series, from the clarity of pop and rock music with a narrow dynamic range all the way to the spatial impression of classical and jazz music with a wide dynamic range. The most distinct characteristic of the A8000 is that it realizes such sound quality not by its ability to create sound capable of attracting a small number of wild fans through its strong individuality, but rather sound aimed at greater universality.

The Feeling of a Customized Fit
Based on the IEM chassis design developed for the B series that has become established as an ideal solution, the A8000 realizes a superior sense of fit. Whether or not the fit of earphones feels superior is determined by the sense of oppression. While at first glance it may seem correct to select an ergonomically praised organic shape to be held in place by the elasticity of silicon, this places ordinary pressure on the ear that serves as an unwary burden and leads to accumulation of fatigue. In limiting the area of contact in comparison to an organically shaped surface that comes in contact with a large area of the ear, this product aims for a sense of fit with no feeling of oppression. For that reason, it is suitable for the ears of many different people. If there is no feeling of oppression at any of the points of contact, that makes for such a comfortable, superior feeling of a customized earphone fit.

Precisely Cut Stainless Steel Chassis with "Tetra-Chamber Construction"
The volume and shape of the chambers in front of and behind the dynamic drive unit have a great impact on sound quality. Particularly, operation of the newly developed true Beryllium driver is extremely delicate, and it is impacted greatly by the spaces in the chassis. The internal design of the chassis can be calculated to some extent through simulations, but after that repeated trials of an actual product must be conducted until the sound quality targets are reached. For the A8000, in order to optimize operation of the driver, the inside of the driver unit chassis is divided into four chambers (Tetra-Chamber Construction); the driver ante-chamber and the double construction driver post-chamber and the MMCX connector portion are separated into different chasses. The driver is direct mounted into the ante-chamber of the chassis by a design that suppresses unnecessary vibration to achieve a distinct sound contour. Additionally, the use of four chambers achieves a balance between volume and tightness in the low-range while at the same time preventing leakage of sound.

MMCX Connector＆Original High Purity OFC Silver Coated Cable
The MMCX connector was developed in-company. We've used high-purity OFC silver coated cables that provide a wide sound stage. These jointly-developed cables were originally designed by and are currently manufactured by the well-renowned Junkosha corporation for the purpose of being used with the supercomputer "Kei" due to their fast signal transmission speed. The insulator film is made from PFA which was also developed by Junkosha who used their extensive know-how through the JUNFLON® brand to create the ultimate in low-permittivity material. The outer tube is made from PVC for maximum flexibility. The user will experience surprising flexibility that both makes the cable extremely easy to use as well as reducing the likelihood of microphonics. In addition, the MMCX plug and the 3.5 mm mini-plug have a tendency to disconnect so we've far exceeded the regular QA pass criteria of a 5,000-time bend test by changing the connection design to one that can withstand more than 50,000 bends.

Junkosha: The Japanese corporation Junkosha develops and manufactures products such as high speed coaxial cables that boast the world's fastest transmission speed at 95% the speed of light, as well as cables for demanding fields such as marine and aerospace, healthcare and power generation facilities. These special cables require a high level of technology and center around fluoropolymers. Junkosha's cables are often called by the brand name JUNFLON® and have earned the tremendous trust of engineers requiring special-purpose cables.

MMCX Assist for Easy Plug Removal
An item for the smooth insertion and removal of earphone cables using an MMCX connector. Using MMCX Assist the plug can be removed with surprising ease by applying proper force to the MMCX connector in the direction for cable removal. It also prevents the contingency of the cable from becoming severed by mistakenly pulling on the cable portion of the MMCX connector plug.

Ear Hooks that Alleviate Cable Touch Noise (Incorporates Lock Mechanism)
An ear hook is effective in reducing touch noise; wearing it when walking dramatically reduces the unpleasant rustling sound that may occur when the cable rubs against the body (cable touch noise). In the past, our company’s ear hooks have characteristically been slimmer than ordinary and virtually indistinguishable from a wire or rosin filled cable, making it so comfortable that it is easy to forget that one is even wearing it. This time we have newly added a cable lock mechanism.

Original Eartips with a Color Difference Between the Left and Right Bushes
Two types of silicon differing in rigidity are employed for the sound conduit and for the earbud that comes into contact with the user’s ear. The silicon used for the sound conduit is more rigid than that used for the earbud, and by having groove processing applied to it, combines both strength and flexibility. Soft silicon has been employed for the earbud, making for a comfortable fit and a high level of sound insulation.

One of the bushes is gray, while the other is red; by pulling the earpiece back slightly to check the color of the bush, it is easy to distinguish between left and right, even in places with subdued lighting. Since the bush colors of neighboring sizes are different (the gray bushes alternate between dark and light gray; the red bushes alternate between red and pink), it is also easy to distinguish between sizes.

Comes in 5 sizes – SS/S/M/L/LL

Interchangeable Dust Filter
The open portion of the dust filter may become soiled with earwax, etc. For the A8000, we have shaped the dust filter in such a manner that it can be removed and replaced by the customer, and a replacement dust filter is included as an accessory.

Aluminum & Silicone Hybrid Carry Case
The aluminum carry case has been designed to strike a balance between fitting in your pocket and protecting the A8000. Cut aluminum is used for portions to which force is applied. The interior is a soft silicone dome to prevent scratching. Attention to detail is evident by other labor, such as inclusion of an internal partition to prevent the chassis from getting scratched by moving back and forth.

How to Wear the Earphones
This product is an earphone that is hung over the ear. The transmission of touch noise to the ear can be prevented by placing the cable on the ear to achieve a comfortable fit.

1. Confirm the R and L marks on the inside of the chassis. R is right, and L is left.
2. Run the cable toward the front from behind the ear, and insert the earpiece of the earphone into the ear.
3. If it is difficult to fir the earphone into the cavity of concha, try to insert the earphone while pulling back and somewhat upward on the ear lobe.

If the cable does not fit on the back of the ear, please use the ear hook accessory. If the fit is too loose, try changing the size of the sleeve. In some cases, the size of the left and right earpieces may be different.

Aging
Aging is a phenomenon by which sound changes by continued use over a certain period of time. A driver unit produces sound through the vibration of an extremely thin heat-formed film. The cause is not clear, but it is thought that the film might become accustomed to the stress applied from the forming of the film or stress from the adhesive through continued use over time so that minute signals can be transmitted easily. A long period of time is required before the aging effects on this product become unnoticeable. Generally, through 150 to 200 hours of ordinary use sensitivity increases to achieve the level of sound quality for which the product had been originally designed.

Sound Quality Reviews
Sound is not muddy at all, extremely high clarity. The vocals and instruments comprising music can each be heard perfectly, and music can be enjoyed with a good feeling. Offers unparalleled reproduction of sound from percussion instruments, piano and other instruments for which good sound build-up is particularly demanded. From classical music to pops, rhythm can be vibrantly delineated. Furthermore, each sound is localized as a silhouette floating in space, as a preface to that, every nuance of vocals is perfectly reproduced, therefore new inspiration can be attained from familiar tracks of music to which one has already become accustomed.

If you need portability and simplicity above all else in an audiophile quality DAC, the DragonFly Cobalt is what you’re looking for. With the right mix of simplicity, extreme portability, and sound quality, the DragonFly Cobalt is a great tool to help you bring out the best in your music wherever you go. Read our full review here.

From AudioQuest
DragonFly Cobalt, our new flagship DAC, takes what music lovers around the world have come to expect from the multi-award-winning DragonFly family—naturally beautiful, seductive sound—and strips away fuzz and fog that weren't even noticeable until Cobalt removed them.

How is this possible? Like the critically acclaimed DragonFly Red, Cobalt has the robust 2.1-volt output to drive almost any headphone, uses a bit-perfect digital volume control for outstanding signal-to-noise ratio, enables seamless compatibility with Apple and Android devices, and is an exceptionally competent and affordable MQA Renderer.

AudioQuest, Gordon Rankin: A Beautiful Partnership
Like all previous DragonFly models, Cobalt uses Gordon Rankin's precedent-setting StreamLength® asynchronous-transfer USB code. Further, in Gordon's monoClock® technology, a single ultra-low-jitter clock generated from the ESS ES9038Q2M DAC chip runs the ESS chip functions as well as all microcontroller functions. This superior clock enables DragonFly Cobalt to provide greater resolution and clarity than DACs with multiple clocks.

Why the "Slow Roll...?"
Cobalt employs ESS's new flagship ES9038Q2M DAC chip. While the chips used in DragonFlys Black and Red are unbeatable for the price, the minimum-phase slow roll-off filter in the 9038 results in naturally expressive sound that is always emotionally engaging and never fatiguing—a beautiful combination of warmth and detail that we find equally exciting and soothing.

Killing the Noise
In Cobalt, we've taken what we've learned from our recent research and development in noise dissipation to employ power-supply filtering specifically designed to dramatically reduce the increasingly prevalent noise from WiFi, Bluetooth, and cellular signals. Successfully combating this noise is absolutely crucial to the preservation of the lowest-level musical details, particularly when it comes to high-res audio—and especially when applied to a portable-audio device such as DragonFly.

Bit-Perfect Volume Control and 2.1-Volt Output
Cobalt features the same ESS Sabre 9601 headphone amp and bit-perfect volume control that give DragonFly Red its unique combination of power and grip over the music. This solution ensures maximum fidelity, thrilling dynamic contrast, and excellent signal-to-noise ratio. The 2.1-volt output makes Cobalt and Red compatible with a wide range of headphones, including power-hungry, low-efficiency models.

Firmware Upgradeable
DragonFlys Black, Red, and Cobalt are firmware upgradeable via our free Desktop Device Manager. In today's fast-paced digital world, longevity in a hi-fi component is increasingly rare—at any price.

Read Our Full Empyrean Review

From Meze 
A blend of premium materials, exquisite craftsmanship and detailing that’s unmistakably Meze, Empyrean is one of the most technologically innovative planar magnetic headphones in the world.

“Empyrean was born from passion, curiosity and innovation. As a business, we have allowed ourselves the freedom to experiment and take risks in search of the perfect sound. To generate something truly remarkable, one must dare to explore, and that’s what we did with Empyrean. We pushed and refined industry’ standards and achieved a true game changer for audiophiles.” – Antonio Meze, Lead designer and Founder of Meze Audio

Empyrean is the product of two passionate companies coming together to explore what is possible beyond their individual capabilities. The result is a no-compromise headphone embodying Meze’s daring aesthetic and user-centered design approach and Rinaro’s experience in research and development within the field of planar magnetics. Rinaro, a progressive audio company, has at the heart of its technology an R&D team that has been at the forefront of planar magnetic development since the 1980’s. What originally started as a state-funded initiative with a focus on innovation has now entered into a new chapter of audio progression with the opening of a cutting-edge industrial facility in Ukraine.

Over 30 years of research and development have led to the creation of the first Isodynamic Hybrid Array driver.

From Astell&Kern
The SR25 is the second model in the Astell&Kern A&norma standard line. Beginning with the AK70, Astell&Kern's goal was to bring high resolution audio and the Astell&Kern sound to more music lovers. This goal continued with the successor to the AK70, the A&norma SR15, and now evolves further as the SR25, a premium product that fully embraces Astell&Kern's philosophy and technology, now available to the masses. The SR25 is the latest answer to our never-ending question of "How do we get closer to the original sound the artist intended?" 

The SR25 improves on the SR15 by:

• Adding a new, faster Quad-Core CPU paired with the Dual Cirrus Logic CS43198 Master Hi-Fi level DAC, first used on the SR15
• Native playback support for DSD256
• A new class-leading performance mode for ultra-high quality playback without compromise
• Newly designed circuitry to improve sound quality enhancements
• Addition of Bluetooth LDAC codec to give users more options for higher quality wireless sound
• The essence of Astell&Kern's philosophy that sound quality is never compromised is exemplified in the SR25, which expresses every musical detail and bit-perfect playback as only Astell&Kern can. 
   

Performance Mode for Ultra High Resolution Sound

The SR25 supports native DSD256 and 32bit/384kHz audio for the first time in an Astell&Kern standard product and boasts performance that cannot be compared with other competitors' products.

The SR25, which is smaller than other players, has been developed to achieve stable, ultra-high resolution sound. We have developed a new Performance Mode with the SR25 that automatically optimizes and sets the memory mode in the system according to the data size of the source being played.

As the resolution of the sound source increases, it is necessary to process a large amount of data rapidly. If this part is not optimized, sound breakup may occur. To prevent this, the SR25 uses the new Performance Mode to adjust and optimize the system in order to produce near perfect sound quality when playing back high resolution audio.

Experience ultra-high resolution with the SR25's Performance Mode, which reproduces even the smallest, minute details of the original recording the artist was looking for, without compromise.

Perfect Circuit Design for the Highest Sound Quality

Proper playback of DSD256 and 32bit/384kHz digital audio requires a high-performance CPU and fast memory speed, along with an audio path suitable for high-speed signal processing.

Optimizing the length of the audio path is a very important part, as failing to properly do so can create a time delay between the signals resulting in sound abnormalities.

With the SR25, the Astell&Kern team developed a completely different PCB design from the existing SR15 to process the high speed signals where required, resulting in audio path lengths that are the same, allowing for super-high resolution sound without any delay.
Furthermore, newly designed audio patterns and power circuits for distortion-free signal transmission and noise rejection are applied to each channel.

The result is an Ultra Low Noise Filter that allows you experience Astell&Kern's flawless sound, with Zero Noise, on the SR25.

Embark on a Musical Journey That Lasts the Entire Day

If the power supply's stable design and efficiency are not properly taken into consideration, the input/output voltage difference becomes large, and when the output current is large, the output voltage can become unstable. This leads to excessive noise being generated, which can be a major cause of poor sound quality. In addition, poor power efficiency will result in a shorter playback time.

The SR25 set a big challenge for the Astell&Kern engineering team – add the longest playback time of any previous Astell&Kern product, while maintaining the signature Astell&Kern quality sound, and a low-noise floor.
In the SR25, the team not only applied highly efficient components, but they focused on developing circuit optimizations to get the most out of their performance.
The result is up to 21 hours of continuous play time, more than double the previous generation SR15, with no compromise in sound quality.

No need to worry about battery life while on your daily journey, just have fun on your Music Trip with the SR25.

Continuous Playback Time

* Standard - MUSIC: FLAC, 16-bit/44.1kHz, Unbalance, Volume 80, EQ OFF, LCD OFF

No Compromise on Sound, Even When Connected Wirelessly

In addition to 24-bit music playback via aptX^TM HD Bluetooth as in previous Astell&Kern players, the SR25 adds LDAC support to give users more options to listen to high resolution audio wirelessly.

Now you can enjoy Astell&Kern's high-quality sound when paired to Bluetooth earphones, headphones and speakers.

Astell&Kern's Exclusive Metalworking Technology

Astell&Kern products are often compared to art sculptures, with colorful faces and angles not found in other products. This precise design work is based on Astell&Kern's long accumulated know-how and highly precise metalworking technology.

In order to produce this unique style Astell&Kern is famous for, 5-axis machining is performed instead of traditional 3-axis machining used in general machining. All metal must be processed at once without interruption.
In addition to 5-axis machining, Astell&Kern has perfected it's crafting of metal through thousands of hours of trial and error. Only after mastering these techniques that Astell&Kern has developed, can the beauty of the metal shine through.

The vibration-free processing machines used by Astell&Kern are the same ones used by expensive Swiss luxury watch manufacturers. This is reflected in the crafting of the volume wheel which is processed precisely like the crown of a luxury watch for the best operating feel.
Astell&Kern products are designed to achieve perfect integration at whatever angle you look at it in your hands.

The Aluminum body on the SR25 provides maximum sound quality, while suppressing noise as much as possible. The use of laser ground extension technology gives you the best sound possible, without interference or distortion.

Astell&Kern combines these small parts to make a big difference in the quality of our products that no other manufacturer can match.
