Sound Signature
You're probably looking to see how these IEMs stack up on sound. We'll share our thoughts here, although keep in mind this information tends to be anecdotal and subjective.
U12t Sound Signature
The U12t features a neutral, reference-level tuning known for its accurate, detailed, and immersive sound presentation. It is the perfect in-ear monitor if you're looking to scrutinize every note and detail in your favorite music.
The bass in the U12t is well-balanced, delivering good impact and rumble when needed. Its midrange is natural and clear, allowing voices to come through with life-like clarity. Its soundstage is one of the largest you'll hear in an IEM, offering accurate sound placement for an immersive sound.
Xenon 6 Sound Signature
The FiR Audio Xenon 6 offers a warm sound signature, highlighted by powerful and tactile bass, combined with smooth and natural vocals and instrument presentation.
The bass is the highlight of the Xenon 6's sound. Bass power, texture, impact - the RN6 has it all, and with Kinetic Bass technology, you can hear and feel the bass simultaneously for a truly next-level sound like no other. Midrange is natural and life-like, offering weighty vocals and instrumentals. You can hear details effortlessly, but music never sounds harsh or fatiguing.
Soundstage on the FiR Audio Xenon 6 is wide and immersive. Vocals, instruments, and other sounds are easy to pinpoint, which makes for a very immersive sound that makes you feel like you're part of the recording.

Our Thoughts
The 64Audio U12t delivers reference-level resolution, detail, tone, and an immersive soundstage. It is the IEM to get if you want to experience an authentic studio-quality sound. Music on the U12t sounds clean, clear, and accurate - no matter the genre. The 2025 version is even better - boasting an updated design and accessories package without the extra cost. You can swap out Apex Modules to fine-tune the sound to your liking.
The Xenon 6 is not your typical audiophile IEM. Unlike the U12t, which goes for a studio-reference style sound, the Xenon 6 features a bassy, organic, natural, and fun sound signature meant to make every listening session exciting. You'll hear some of the most impressive bass in an IEM, and you can even feel the bass through Kinetic Bass tech. The XE6 features a massive soundstage with a 3D-like presentation that makes music sound alive. Plus, you have the option to tune the sound through ATOM XS modules. If you're looking for an IEM that brings out emotion from your music, the XE6 is the one to get.
Another IEM to consider in this price range is the Empire Ears Legend EVO. The Legend EVO has some of the best bass in an IEM and offers smooth, natural, and accurate vocals and instrumentals.
