HiFiMAN HE-6 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.

The device comes with its own special case or pouch, which is useful for safe transportation.

A long cable ensures more freedom of movement.

A straight plug is better when the jack is on the top or bottom of your player.
