KZ ZSN Pro 2 is a hybrid 1DD+1BA IEM with a metal faceplate, 26Ω impedance and 108 dB sensitivity, tuned with boosted sub/mid-bass and a V-ish voicing. It delivers punchy sub-bass, clear treble and detachable 2‑pin cable flexibility, but has plastic shells, protruding 2‑pin sockets and stock tips that can muddy mid-bass; solid for budget listeners who want bass impact and modular cables, less ideal for neutral audiophiles.
Buy if you want a bass-forward hybrid IEM with detachable cables and replaceable tips; avoid if you prefer neutral tuning or all-metal shells.
