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.
Electron 12 Sound Signature
The FiR Audio E12 features a V-shaped tuning with powerful bass and clear treble. Bass is the highlight of the E12's sound, offering a powerful and tactile feel thanks to Tactile Bass technology.
The E12 is especially outstanding in slow, bassy music where the powerful 12mm dynamic driver can stretch its legs. Kick drums sound full, powerful, and impactful, while bass guitars get remarkable detail and texture - you can feel the bass notes vibrating with every pluck of the bass guitar.
The midrange and treble complement the powerful bass, offering accurate playback for vocals and instrumentals without harshness.
The soundstage is spacious. Instruments/sounds are well-separated, creating a 3D-like listening space for an immersive listening experience.
Price and Value

Tactile Bass technology elevates the bass experience for a sound you can hear and feel, while built-in ATOM venting delivers enhanced comfort by preventing pressure build-up.
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 FiR Audio Electron 12 is an exciting IEM with a unique tuning meant to deliver an exciting listening experience rather than outright accuracy and precision. With its impactful and tactile bass, solid build quality, and seamless customizability, the Electron 12 lets you enjoy your music to the fullest in style.
