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.
Neon 4 Sound Signature
The FiR Audio Neon 4 offers a warm sound signature, characterized by its impactful bass, recessed midrange, and smooth treble.
Bass is the Neon 4's strong point, delivering strong and punchy impacts - perfect for genres like R&B, Hip-Hop, and EDM. Kinetic Bass enhances the overall bass experience significantly, delivering rumbles and impacts you can feel. The midrange on the Neon 4 is smooth and slightly recessed. Vocals and instruments are pushed back in the mix, which gives a more immersive listening experience rather than an intimate and detailed one. The treble is smooth and free of harshness.
The Neon 4's soundstage is wide and deep. Instruments are well-defined, and their positioning is easy to pinpoint in the mix.
