The near constant release of new IEMs means that there are loads of great options for audiophiles, but it also means that it’s harder than ever to sort through the available options and find the set that’s going to be best for you. In this guide we’ll cover the basics of what differentiates one IEM from another, and provide some recommendations based on some of our favorites from the Bloom office.
Price, Performance, and Preference
Probably one of the toughest aspects to sort out in the IEM world is untangling the relationship between price, performance, and your personal preference for sound. If you mostly listen to hip hop, a $2000 IEM tuned for classical music might sound worse to you than a $100 IEM with a tuning better suited to hip hop, but an experienced classical listener will be able to describe 100 ways that $2000 IEM enhances their listening experience. Generally speaking IEM tunings fall into three categories: Reference, Balanced, and “Fun,” with different tuning styles being good for different genres or just listening preferences.
A Reference tuning is focused on accuracy above all else. Often a tuning target like “diffuse field” is used, which only boosts or cuts sound frequencies with the goal of sounding like well-tuned speakers in a treated room. Reference tunings are often preferred by fans of classical music since the wide range of instruments requires accuracy across the frequency spectrum.
A Balanced tuning enhances different parts of the frequency spectrum to deliver a balance of bass, midrange, and treble that matches broad user preferences. The famous Harman Target is an example of a balanced tuning, as it’s not truly neutral, but sounds “right” to most listeners. Balanced tunings can be good for a wide variety of genres, but can excel at specific ones depending on how the bass, vocal range, or other characteristics are managed.
Fun tunings typically start with a more balanced sound, and then enhance specific parts of the frequency spectrum for a more unique sound. Most often this means boosting the bass or “scooping out” the midrange to create a tuning that sounds more energetic, and – well – fun. Fun tunings tend to be good for pop, rock, hip hop, and in general, genres that favor impact and engagement.
Along with that, IEMs have different ways of presenting Soundstage, Imaging, Detail, and Resolution. Soundstage is the perception of a room or space that the music is happening in. Imaging is how clearly you perceive different instruments, voices, and sounds, and their placement in the room. Detail and Resolution describe the ability of the IEM to present the finer details of the music present in the recording – the sense that, if the recording was of high enough quality to capture the sound of a pin dropping in the studio, then these IEMs would let you hear that pin drop.
While there are many IEMs with excellent tunings available at very low prices, and there are some inexpensive IEMs which have a surprisingly large soundstage or impressive imaging, typically you need to go up in price to get a better balance of tuning, soundstage, imaging, and resolution.

Driver Types and Capabilities
There are five main types of drivers you’ll find in IEMs, each with unique characteristics and capabilities: Balanced Armature (BA), Dynamic (DD), Planar Magnetic (or just “planar”), Electrostatic (EST), and Bone Conduction (BC)
Dynamic and Balanced Armature are by far the most commonly used driver types in IEMs, and both can accurately reproduce the full range of bass, midrange, and treble. Balanced Armature drivers are known for their fast response and tight, accurate delivery. Their small size means that IEM creators can use large numbers of Balanced Armature drivers in a single IEM. Dynamic Drivers are the most commonly driver types across all kinds of headphones. They’re known for having the most natural timbre of any driver type, and they produce a larger displacement of air than other IEM driver types which can result in dynamic drivers offering a physical, dynamic feeling that other driver types can’t reproduce.
Planar Magnetic drivers offer a balance of the characteristics found in Dynamics and Balanced Armature drivers. They’re similar to Dynamic drivers in their ability to be used as a single driver representing the full frequency range, while also providing a good sense of physical impact. They also offer speed and an articulate presentation similar to Balanced Armatures.
Bone Conduction and Electrostatic drivers are more limited in their capabilities, but excellent for more specific purposes. Electrostatic IEM drivers are generally only used for treble. Their ability to quickly and precisely reproduce ultra-high frequencies makes them perfect from treble in IEMs that use multiple driver types. Bone Conduction works by vibrating and resonating with the inner ear. They’re most frequently used for bass, but can also be used for other frequency ranges as they can expand the sense of space in the sound.
While many IEMs use only a single driver (most frequently a single dynamic driver like the Moondrop Aria) or multiple of a single type of driver (like 64 Audio’s multi-balanced armature IEMs, with as many as 18 drivers in each shell), IEMs which use multiple driver types are becoming increasingly common. Hybrids use two different types of drivers, Tribrids use three, and Quadbrids use four. Any of those types can use any number of total drivers, with some Quadbrid IEMs like the Empire Ears Raven using as many as twelve – 1 bone conduction, 2 dynamics drivers, 5 balanced armatures, and 4 electrostatic – while some hybrids may only use as little as two drivers.
Picking the IEM that’s Right for You
With tuning, technical performance, and driver types and combinations all taken into account, in most cases price is going to be the final deciding factor. Thankfully, the recent explosion in IEMs has provided a number of solid possibilities across the price range.
Under $200
For under $200, Moondrop May provides a balanced sound signature, and is a good all-arounder for anything from pop to classical. It has a strong build and design especially considering its $74.99 price point. If you’re looking for a more fun sound that’s more focused on rock, pop, and hip hop, DUNU Titan S2 is a single dynamic driver IEM with a warm, bass-boosted sound, and a really nice build and design for $79.
At $159, Meze Alba is also a single driver IEM, but provides a sound signature that’s just slightly warm with a sound signature that’s closer to neutral. Alba provides great timbre which makes it perfect for music that use primarily acoustic instruments ranging from folk and rock to classical. If you’re looking for a little more wow factor though, Ziigaat Arcadia is a $199 hybrid IEM with one dynamic driver and three balanced armatures that offers a sound that has a strong focus on detail in the midrange and treble, almost leaning towards a reference sound until the strong boost in the low-end hits, giving you powerful thick bass to complement good overall performance.

Moving the price up a little bit, you’ll find the FATfreq HBB Deuce, which features dual dynamic drivers, and delivers an insanely powerful low-end for $239. Deuce isn’t just a bass monster as it provides solid vocals and a good sense of space and imaging as well. For $249, if you’d rather have a balanced experience that leans more towards a reference signature, the Kiwi Ears Orchestra Lite trades pounding bass and big impact for stronger detail and resolution.
DITA Project M is another strong performer that sits in between the balanced and reference styles of tuning, offering an incredibly natural sound and surprisingly all performance from a single dynamic driver and $325. DUNU DK3001 Braindance trades some of Project M’s natural character for the speed and precision of four planar drivers in its tribrid driver configuration, and it adds a nice size bass boost at the bottom to combine fun with technical performance.

Priced at $600, Moondrop Variations delivers the sort of tribrid experience listeners might expect to spend thousands of dollars on for a fraction of the price. With its balanced sound and strong technical performance, Variations has become a benchmark for other IEMs since its release. 7th Acoustics is a relatively new player, but Supernova took the IEM world by storm with its incredibly transparent, natural tonality. It uses six balanced armature drivers, but most listeners would swear that there’s a dynamic driver based on its excellent timbre and that exceedingly natural overall sound.
For a more reference-like experience, 64 Audio Aspire4 was designed as a reference monitor for aspiring musicians, but it’s excellent detail and clear, transparent sound have made it a favorite for audiophiles as well. Thieaudio Origin is another IEM to exceed all expectations for what’s possible at its price point, offering a 8-driver quadrid, with bone conduction, dynamic, balanced armature, and electrostatic drivers that sounds like a top of the line flagship IEM for $849.

At $1299 Thieaudio Prestige LTD sounds incredibly clean, precise, transparent, and well-balanced. Genres like fusion and progressive rock that need a tight, articulate presentation sound amazing, and the tonal balance makes it a good generalist as well. Similarly, 64 Audio U4s offers a sound that sits in the sweet spot between a slightly warm, balanced tuning style, and a highly detailed technical performer.
If you’re craving a basshead IEM with impeccable craftsmanship and flagship-like characteristics, Empire Ears Triton delivers massive bass, alongside of the total premium IEM package – both sonically and visually. For our office favorite in this price range, you’ll want to check out Ice Lab Spectrumica. Spectrumica offers soundstage, imaging, and clarity that rivals the very best on the IEM market.

Top of the Line
For a fun, energetic, v-shaped sound, the 64 Audio Volur is hard to beat at any level. Its spacious soundstage and strong resolution mean it offers insight into the music and dynamic fun all at the same time. Campfire Audio Trifecta is another top of the line IEM that leans towards the “fun” end of the spectrum, but Trifecta offers a sound that’s massive and feels like a headphone compressed into IEMs. There are few IEMs that capture classic rock as well as Trifecta with his warm, lush sound.
Vision Ears EXT MK2 is probably the most natural sounding IEM I’ve heard, with near perfect timbre and tonal balance, along with incredible detail. EXT MK2 features a unique hybrid design, with two dynamic drivers and four electrostatic, which results in natural delivery and fast, crisp highs. In terms of raw “wow” factor though, it’s hard to beat the Empire Ears Raven, a 12-driver quadbrid. Raven offers a massive soundstage, holographic imaging, and incredible detail, alongside of deep, powerful bass, and strong detail and resolution.
