The Nokia BH-103 is a stereo headset designed for use with Bluetooth enabled devices. You can listen to music with the provided earplugs and let the device notify you by muting the music when a call is being received. Buttons on the device allow you to adjust volume, answer and end calls, power on and off and more. Status LEDs are also included which indicate call status and battery power. The bluetooth receiver sits around the wearer's neck with wired-attached headphones that go behind the head.
