FiR Audio Neon 4 通用型入耳式監聽耳機

The bass is tight and punchy, but it’s the treble that really shines—so airy and detailed without ever getting harsh. I’ve been listening for hours and my ears don’t feel tired, which says a lot. These just make everything sound effortlessly smooth.

The creamy upper mids on these are just gorgeous for acoustic tracks, and the treble has a smoothness that makes cymbals sound natural without any harshness. I've been using them for jazz listening and the resolution is surprisingly detailed for such a warm signature.

Ordered these for long mixing sessions and the upper mids are so lush and creamy without being harsh, exactly what I needed. The treble has a stellar sense of air that really opens up the soundstage.
