The driver unit is the component that produces sound in the device. Bigger drivers are more powerful and can produce better bass.
4.Has an over-the-ear form
vs No (58% don't have it)
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.
