Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.
The device comes with its own special case or pouch, which is useful for safe transportation.
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.
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.
