Community Insights: 64 Audio U12t Review

The 64 Audio U12t are one of those legendary headphones that don’t need much introduction. Let’s dive in deeper and see what makes these IEMs so special.

First Impressions

You can tell that 64 Audio have a long history on stage. The U12t accessories also embody this. Everything you need comes with the headphones. A bunch of ear tips to play with, a very high-quality leather case to protect your IEMs while you’re on tour and a basic cable that you can clip to your clothing, so the in-ears don’t fall on stage.

The U12t can be used in a variety of ways, due to their robust workmanship and versatile sound.

A key reason for this is the Apex system from 64 Audio. By changing the small dampers, you can actually change the openness of the headphones and their bass response. This means that the mX module, for example, turns the U12t into an open IEM with a wide stage. This module is very comfortable for long sessions and is very suitable when used as a headset, thanks to its open design (you can better hear your voice while speaking)! Yes, I’m serious: I prefer to use my U12t in the office with a microphone cable for long video calls.

The m15 and m20 apex modules achieve greater isolation of ambient noise and a significant increase in bass. This means that the U12t loses a little stage width, but it is much more energetic and suitable for louder environments such as a café. In my opinion, however, it is not made for louder environments like the subway.

What are the advantages of the U12t?

• Versatile across all genres, thanks to output tuning and Apex

The U12t is not bad in any genre. On the contrary. I’m happy, well above average with the U12t in most genres. But where it really shines is in orchestral music. I lose myself with the U12t in soundtracks, especially in film music such as Star Wars, Lord of the Rings and Interstellar. The deep timpani beats, the extremely wide and very deep stage make listening to music a wonderful experience.

• Soundstage and imaging

The best stage I’ve ever heard with a IEM! With every Apex module, the centre image is razor sharp, like no other earphones! The level of clarity and detail is in general very good. The lower the isolation of the Apex modules, the wider the soundstage.

• Comfortable fit

I don’t think anyone will have any problems with the fit. The aluminium housing has no sharp edges and quickly reaches body temperature, making it comfortable to wear.

• Structured bass

The bass goes infinitely deep and is super detailed, even if it’s powered exclusively by Balanced Armatures. With the more isolating Apex modules, the amount of bass increases, but never becomes excessive.

The special thing about the U12t is not that it’s perfect in so many contexts (except perhaps on stage), but that it is so universal. However, there is one issue that curbs my joy: tonality.

When I compare the U12t with my ThieAudio Monarch MKII or the Empire Ears Odin, I find that the U12t sometimes makes voices seem artificial. But, as I said, I only notice this in direct comparison with other models, and only with voices.

The Final Word

In my opinion, the 64 Audio U12t might be the only IEM that suits most people. They look elegant, feel good and the 2-pin connector makes it easy to upgrade to a cable of your choice. The Apex system turns the headphones into sometimes extremely wide, then bassy, open and closed headphones.

In every aspect, the U12t proves itself as the definitive choice for those seeking versatility and performance.
