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.

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.

I love this, is amazing sound

Amazing

Im doing an honest review im not new to this sound signature the closest thing to how these sound are an expensive car audio system with subwoofers these iems have crystal clear vocals and a soundstage that sounds separate from the bass and the bass is deep clean and loud these are the best iems I've ever heard 5 stars for sure

The Fatfreq Deuce punches above its weight!

I received the Farfreq Deuce iem’s today and wow. Yes they have more than average bass, but not so much that I couldn’t listen to them all day. Very detailed and well rounded sound, especially for the price. Thanks to Bloom for being awesome and getting these shipped to me asap!

I like bass. I like these.

If you ever thought to yourself "I wish I had headphones that would absolutely murder my face with bass", these are the IEMs for you. I was prepared for mud. As a basshead, mud is my reluctant home. You don't WANT mud, but you accept it, because it's always there. Except this time it's not. This is warcrime levels of bass, and it's clean. OK, I hear you say, but what about with the included bass boost adapter? Surely that has to introduce mud. Nope. Still no mud. Medium gain on my DAP (R4) which has class A amplifiers, clean as can be.

Well ok so it has clean bass. Surely the mids and highs are problematic. Nope. The mids are a bit recessed, but I knew that before I bought them. The highs are.. well I can't hear anything over about 15k (thanks Motorhead!) so I might not be the best to opine on the highs here, but it's unobjectionable to me. They're there. It's not bright, it's not veiled, just.. slightly crisp? Overall I dig these IEMs. Are there better bass cannons out there? Maybe. I donno. There are definitely worse ones out there for similar money.

As for sales/service, Bloom shipped these super quick; I ordered them on a Sunday and I had a tracking number before 9am Monday morning. I'll definitely be back for more headphones from Bloom Audio.
