HiFiMAN HE-400 review: specs and price

Comfortable full-size form with earcups that fully enclose your ears. This model is loved for its increased sound isolation and the fact that it won't leak sound to your neighbors. It offers potential for maximum bass and loudness levels.

With a detachable cable you can use alternative cables, and if the cable is pulled it will pop out instead of breaking.
