The Sony DR-BT160IK consists of a Bluetooth headset (DR-BT160AS) using Version 2.0+EDR and a wireless transmitter/receiver (TMR-BT8iP) for iPod or iPhone. The headset allows you to listen to the audio files stored in your Bluetooth Stereo-enabled audio device as well as to talk on your cell phone with Bluetooth capabilities, sans wires. This is possible even if your music player or phone is in your backpack or briefcase, or 10 meters away from you. If you have an iPod or an iPhone without built-in Bluetooth, plugging the transmitter/receiver into them enables a connection with the Sony headset.
The speakers on the headset are ear bud types with a bullet shape that are designed to block out outside sound without getting into the ear canal. These improve sonic quality as well as wearing comfort. The ear buds are attached to an earpiece shaft that is adjustable thus allowing it to match different ear sizes. The shaft, in turn, is connected to a behind-the-neck support that provides a secure fit even when working out in the gym or running along tracks or trails. Such support is made of soft elastomer making it flexible and comfortable to wear.
You can control your music player remotely through the headset via the Bluetooth connection. Buttons are incorporated into it allowing you to play, pause, skip, reverse, fast forward, or stop the music. When making a cell phone call, an embedded omni directional microphone allows hands-free conversation.
Power is supplied by a rechargeable lithium-ion battery in the headset. It has an approximate life of seven hours of continuous music playback. When fully drained, it takes 2.5 hours to a full charge.
