The Sony MW600 is a feature packed Bluetooth headset that includes built-in caller ID display, FM radio, game devices, Bluetooth enabled music play, A2DP music streaming, and call conversation. The MW600 relies on using OLED technology to help display the important information like caller ID.

The AVRCP remote control and A2DP music streaming technology makes it easy to play stereo audio and music on the phone or similar supported devices. Also, the headset makes it possible to pause, play, or select tracks with the various buttons on this Bluetooth device. The MW600 is easily charged using a USB power connection or AC charger. At full charge, the device will operate for about 2.5-3 hours. Avoid overcharging to maintain longer battery / product life. DOWNLOAD SONY MW600 MANUAL HERE
