64 Audio U4s 入耳式耳機 - 開箱品

I was a bit hesitant about open box, but the U4s arrived in pristine condition with all accessories. The clarity across the frequency range is exceptional, especially how the midrange handles complex tracks without any muddiness.

Was nervous buying open box but this thing arrived looking untouched, no scuffs on the shells at all. The bass hits deep without muddying the mids, and I've been wearing them for hours without any ear fatigue. For what I paid, this is easily the best value in my collection right now.

The open box unit I got honestly looked untouched, no scuffs on the shells at all. Bass hits clean without swallowing the mids, and the isolation is good enough that I forget I'm wearing them on the train. For this price it's a ridiculous value.
