HIBY x FAudio - Project Ace JP 入耳式耳機

These have become my daily drivers purely because of how the shells sit in my ears — the ergonomic shape disappears after a few minutes. The golden titanium diaphragm gives vocals a bite I wasn't expecting at this price. Zero listening fatigue so far.

Swapped to these for my commute and the isolation honestly surprised me, the CNC-carved shells sit deep enough that train noise just fades. The 12mm dynamic with the titanium diaphragm gives vocals a real weight without ever sounding harsh.

These have become my daily drivers for commuting, and the ergonomic shape really does disappear in my ears after a couple hours. The bass from that 12mm dynamic hits hard but never bleeds into the mids, which is exactly what I wanted.
