Jabra’s BT8040 is a mono Bluetooth headset. One of the smallest of its types, the Jabra BT8040 is also A2DP enabled - it can stream music wirelessly from media MP3 players, the Internet, a mobile phone or PC. And with MultiPoint software, you can connect two devices at the same time, so any audio being played (such as music) will automatically pause when a call comes in. Qualified for Bluetooth Specification version 2.0 + EDR (enhanced data rate), the Jabra BT8040 has an operating range up to 10 meters (approximately 33 feet). And when fully charged you should get around 6 hours talk time and a standby time up to 200 hours.
