Soul Electronics SL300GG
With a detachable cable you can use alternative cables, and if the cable is pulled it will pop out instead of breaking.
The device comes with its own special case or pouch, which is useful for safe transportation.
The cable is designed to minimize tangling.
An L-shaped plug is better if the jack is on the left or right side of the device, so that the cable isn't bent, and is less likely to break when the device is in your pocket.
A long cable ensures more freedom of movement.
The device sits tightly in place, creating an acoustic seal which reduces background noise and prevents your music from leaking out.
This type of device allows you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the volume to overcome background noise. Ideal for plane rides and morning commutes.
The battery is removable and can be replaced by the user if broken.
A standard 3.5mm male connector is suitable for use with all MP3 players and computer sound cards.
More microphones result in better sound quality and enable the device to filter out background noise.

There is a control panel on the cable, so you can easily operate the device without having to interact with it.
