Immediately recognized by SAMSUNG devices. The insertion of the active jack automatically adjusting the volume control. This setting is available on the remote control even if the device display switches to standby mode. The cable is flexible and durable, the lovely colors. The earphones come with three sizes of silicone materials are perfectly adapted to the shape of your ear pavilion. They keep well and enable physical activity without fear of dropping them. In terms of sound quality, I find them very balanced in both lower than in the treble. Supplied with extension cable and carrying pouch, they form a very powerful kit, can be a bit expensive but the quality makes up for that.
