Sony RF400 無線家庭劇院耳機 (黑色) - WH-RF400 - 開箱品

I was a bit worried buying open box, but the range on these is fantastic—I can walk to the kitchen while still hearing the movie clearly. The sound quality is surprisingly rich for wireless headphones, and the battery life seems great so far.

Open box but everything arrived in perfect shape, and the RF wireless range easily covers my whole living room even through a wall. The battery life is impressive too—I've gone a week of nightly movies without recharging.

The sound separation is so clear during action movies that I can hear footsteps behind the dialogue perfectly. Even without the box, everything came in like-new condition and set up in under a minute.
