For us, being able to hear all kinds of new high end gear all the time from our great brand partners...it's easy to get jaded. "Oh this new headphone will change everything!" "This DAC is finally going to make you feel like digital music is perfect!" "This cable has gold infused adamantium...now you'll REALLY hear the music as the artist intended!" Hype and marketing hyperbole sucks. But every once in a while, an audio product comes along that truly feels...perfect. Perfect not in that nothing can possibly be better than it. But perfect in that it delivers such a remarkably perfect tonality and timbre in its price range, that you just know it's a triumph. Ladies and gentlemen, the U12t is a masterpiece. If you're looking to invest two large on IEMs, the U12t absolutely must be on your short list. Our highest, highest recommendation.
From 64 Audio
The U12t does it all, delivering immersive sound and impeccable spatial imaging. It's clean highs extend beautifully with a warm and engaging low-end response - just like its custom counterpart, the A12t. Offering reference-level detail, this IEM is among the best for multi-instrumentalists, engineers, sound monitors, and audiophiles.
Each ergonomic shell is machined out of a solid piece of aluminum and finished with an elegant brushed aluminum faceplate.
U12t features the following unique technology:
The tia system is comprised of three major elements: open balanced armature tia drivers, the tia single-bore design, and tia acoustic chambers. All our Custom In-Ear Monitors with tia feature two major elements of the tia system: the tia driver and the tia single-bore design.
An open balanced armature speaker design for realistic resolution and transparency. By opening a balanced armature, the diaphragm becomes fully unobstructed, reducing resonance in the IEM and allowing sound to travel more naturally to the ear.
Tia Single Bore
A huge advancement in eliminating unwanted tube resonance. The large bore itself serves as a sound-shaping chamber and aids the tia high driver in delivering a linear and coherent frequency response. The short sound path provides remarkable high-frequency extension and smoothness. The large single bore also allows for easier maintenance.
Apex, or Air Pressure Exchange, is a pneumatically interactive vent that releases air pressure in a sealed in the ear canal. Apex comes in two variations, m15 (-15dB) and m20 (-20dB).
Alleviate Listener Fatigue
When you seal a miniature speaker in an ear canal, the air inside becomes trapped. Apex relieves this air pressure, allowing the eardrum to move naturally, so you can comfortably listen longer.
Extend The Soundstage
Freely moving air extends the soundstage and provides a more natural listening experience. It also preserves bass frequencies and helps the listener distinguish individual instruments.
Hear Your Audience
Custom in-ear monitors provide amazing isolation and help you hear your mix more clearly and at lower volumes than a wedge monitor or earbuds. Apex lowers decibel levels while preserving the clarity of the sounds around you, so artists on stage can connect with their audience while protecting their hearing.
LID, or Linear Impedance Design, enables a consistent, reliable sound regardless of what source. This proprietary circuit corrects the non-linear impedances of the drivers, restoring proper interaction with the source and preserving the desired sound signature. Whether you're a musician plugging into a variety of gear at different gigs or studios, or an audiophile listening from low-impedance sources, LID ensures your IEMs are delivering the desired sound signature consistently. And like all our IEMs, this model can be used with a wide range of personal audio devices as well as all hard-wired and wireless monitor systems.

Customer ReviewsWrite a review
My other two IEMs are Shure se846, and Noble Kaiser 10. The U12t has significantly better sound quality than either of my other IEMs, but is not as comfortable as my Shure. The U12t comfort is acceptable, however, with foam tips. I prefer the 64 Audio m20 apex modules and Comply foam Isolation tips. I could not use any of the supplied tips. My chief complaint is the lack of documentation in the package. I had to go to the the 64 Audio website to identify the 3 supplied sets of apex modules (gray = m15, black = mX, silver = m20). I'm using the U12t with my Astell&Kern KANN Alpha, and Moon Audio Bronze Dragon cable, with great results.
I'll be honest i have had a couple of issues where the pins came loose and didn't connect but 64 audio always pulled through. They are so good that i bought their new apex module and another shirt just because they are THAT good, if more modules come out for it ill buy even more. The only other high end IEM i own to compare recently with is the UNIQUE MELODY MEST INT. version (which i bought since my u12t's were being repaired. thought the bass is richer on the um mest, i keep coming back to the u12t's, its CLINICALLY insanely pleasurable to hear and yea i rec them. I must use them everyday I cannot lie. I don't consider myself as a guy with a lot of sound gear and just recently got into the hi end IEM hobby, I'm just glad i went with my gut and bought these babies and also from bloom audio which delivered it really quick! (free chocolate too!!!)
best headphones of any type i've owned. endgame.
