Pairing via Bluetooth is now the technology of choice when it comes to sound transmission without cables. However, some televisions or stereo systems do not have an integrated Bluetooth module or only have an optical output instead of a jack connection. The "Link.it duo" adapter with Bluetooth 5.2 from Hama handles this wireless connection between the devices. It combines transmitter and receiver and connects, for example, a mobile phone with up to two playback devices. Or, conversely, two Bluetooth headphones with a TV, projector or hi-fi system. This is made possible by the connection via fibre optic or 3.5 mm jack cable. The connection options are variable and open up many new possibilities for sound reproduction. Thanks to autopairing, the "Link.it duo" is quickly ready for use - simply pair once and the connection is established automatically when Bluetooth is activated. APTX technology helps to achieve higher audio quality despite limited Bluetooth bandwidth. The Bluetooth adapter draws its power directly from the device via a USB cable. The Bluetooth adapter "Link.it duo" including optical cable is available in stores.
