Our Take

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.

Technology

U12t features the following unique technology:

Tia

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.

Tia Driver
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

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

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.

The 64 Audio U12T have exceeded my expectations

I have loved my Sure 846’s for 7 years. It was therefore with trepidation that I approached getting a new pair of IEMs. Finally, after much reading, I passed on the Campfire (my initial choice) and went for the U12Ts. They have been a great purchase. I am thrilled every time that I listen to them. The sound is just honey for the ears. I've tried several tips but prefer the fit and sound isolation of the foam tips. My only concern is that the two wire cable connection seems feeble but so far it has not given a problem. Wonderful IEMs. Got the upgrade cable as well which is very nice. Great service from Bloom Audio.

Dream IEM and wonderful service from Bloom Audio

My go to IEM for years has been the Shure SE846. I was originally interested int the Campfire Audio offerings but changed my mind and have been eyeing the u12t for several months. On getting the u12t I hours and hours over two days listening to different kinds of music on the SE846 and the u12t both running off a chord mojo or from a Woo WA7 Tube amp feeding from an RME ADI-2 dac. Here is what I found.
Initially I was taken aback by the stage. The voices on the first few songs I heard were set back. Then later I heard other recordings were the voice was front and center. Then I realized that the u12t was probably giving me a better sense of the imaging that the engineer had intended for the particular recording. I was impressed by the placement, detail and separation. Just beautiful to listen to. Whether folk, or jazz, or alternative rock, classical the effect was impressive. After two days of listening and an extended bout of a few hours with the u12t I felt disappointed going back to the se846. It is still a great little IEM but just does not give the experience. There is almost a previously unnoticed muddiness specially in the bass in the se846 that the u12t just dispels. Ended up switching to spinright tips for ease of use but the foam tips were great. Very happy with my purchase. For the enjoyment they give in such a little package well worth the price.
On a side note the service from Bloom audio was superb. They noticed my browsing patterns on the site, courteously asked if they could help and they solved the problem I needed solved to make the purchase. Delivery was prompt and I even got a chocolate bar out of the deal. Very impressed with their responsiveness and plan purchase from them again.

I should not have waited...

There are many positive reviews for U12t. I waited until now (late 2021) and I wish I got this sooner! After cycling through many multi-kilo-buck IEMs, including 64's U18s, I have to say this is the best multi-purpose for me. It has the balance that rivals the likes of Oriolus Traillii. Open, spacious, solid bass, mild-v to neutral tuning, and a good timbre. U18s tops U12t with better resolution and note weight (I took one star for this) but I found U18s lacked openness and dynamics. U12t shows excellent dynamics and the snare rim shot feels like it strikes through my crown. I suppose you can say this doesn't have a "character", but if you are after a neutral monitor, this is it.

Amazing sound quality

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 quite as comfortable as my Shure. The U12t comfort is good, however, with Final Audio Type E tips. I prefer the 64 Audio m20 apex modules. 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.
