Bloom's Take

The FATfreq Deuce has arrived, the highly anticipated collaboration with HBB, also known as Bad Guy Good Audio Reviews. It sports a streamlined, professional look with glossy black housing and subtle branding, and with its sturdy yet flexible Silver 'Blood' cable, the Deuce combines premium aesthetics with a focus on comfort, durability, and incredible value for its price.

Sound wise, the IEM combines FatFreq’s signature bass power with HBB’s tuning sensibilities, delivering a deep, textured low end that satisfies bass lovers while keeping the mids and highs clear and balanced. The Deuce is an ideal choice for anyone looking for both warmth and clarity in a single IEM, and it's a standout among other popular IEM collaborations, particularly for those seeking high-quality bass with a nuanced sound profile.

Meticulously Tuned with Top Reviewer HBB

Over a year, the Deuce was meticulously tuned with top reviewer HBB, also known as Bad Guy Good Audio Reviews, undergoing multiple iterations of tuning and design. Each phase focused on refining sound clarity, depth, and dynamics. HBB's extensive collection of hip-hop, rock, and classical tracks heavily influenced the Deuce's tuning direction, with significant effort spent to ensure it excels in these genres. This dedication has resulted in an IEM that offers unparalleled audio quality and an immersive experience.

FATfreq Tech

BASS CANNON™ (Patent Pending): Using proprietary dynamic woofers, bass chambers and acoustic damping networks, FATfreq was able to design the deepest bass ever recorded of over 30dB, expertly controlled below 150Hz with zero mid-range bleed. A FATfreq innovation pioneered and perfected for sheer bass power.

SONAR LA TROMPA™: Inspired by the anatomy of the traditional french horn, FATfreq uses exponential horn curvature for gain control and to improve treble tonality via acoustics. Providing you with Smooth, natural sounding highs, grounded by a nice timbre in the mid and low frequencies.

PHASEALIGN: The absence of a DSP in IEMs means that FATfreq had to match the phase of multi-way systems via Acoustic delay. Using proprietary structures, they were able to align the low, mid and high frequencies such that they reach your eardrum in a coherent manner. Giving you the sound accuracy and resolution demanded on stage and studio.

Perfect fit

These were a perfect fit for me, not just physically but also sound profile wise. If you're looking for that sub bass presence, like you're at a music festival, this is it. It leaves treble and mids alone to shine while providing that rumble you can feel. Highly recommended.

Deuce Arcadias for me!

open box buy, gorgeous cable, go balanced if possible, these shines with power. Bass cannons or not, lows are very massive, yet articulate and wont bleed at all. Warm signature, analog, think Legato on steroids. Want to thank them both makers for gentle pricing for such amazing GEMs. Next to Arcadias, the Deuce are always enjoyable, constantly on rotation and quite a must addition to any collection. HBB & Friends, please don't stop. And Happy New Year.

Super balanced for a bass head iem

Normally iems that are catered towards bassheads seem to overblow the hell of the bass bleeding into the mids and just sounding overall boomy and sluggish. Something that these do special is the bass although extremely boosted is very controlled and stays clear of the mids. This might be the most balanced bass head iem I have ever tried

Light weight Basshead IEM's

These are light weight basshead iem's. I just used a better sealing ear tip for my ears. These take EQ well and with that I say these are the modern version of the Legato's. The supplied Impedance Adapter are good for those that don't have a proper amp that can supply the additional current that these require to play properly. I ran a CT scan of these IEM's and saw the lay out of the drivers, crossover and vent tubes into the nozzle. Good stuff man.
