Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.
2.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.
The in-ear device is ultracompact and lightweight, with little or no interference with earrings, spectacles, hats, or hairstyles. It is inserted in the ear canal itself and blocks out a lot of environmental noise. It has stronger bass tones and is unlikely to fall out of the ear.
5.has a tangle free cable
The cable is designed to minimize tangling.
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.
