1.has an over-the-ear form
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.
Foldable devices are easier to transport and take up less storage space.
The device comes with its own special case or pouch, which is useful for safe transportation.
A coil cable offers more flexibility, as it can be further extended when in use, as well as retracted to take up less space when not in use.
A straight plug is better when the jack is on the top or bottom of your player.
