The TERRATEC CONNECT BT makes music wireless. The small adapter is easily plugged on the 3.5 mm jack connection of the hi-fi system, of the mobile loudspeakers or another output device and the transfer of music from the Smartphone, Tablet and similar devices can be performed wireless. The correspondingly compatible devices are easily paired via NFC. The integrated accumulator which allows the mobile use of the device and spares the batteries of the terminal by accessing its own storage battery is particularly handy. The TERRATEC CONNECT BT is equipped with a 2.4 GHz Bluetooth 2.1 + EDR receiver. The device is charged via USB.
