Make your speakers Bluetooth*. The Logitech Bluetooth® Audio Adapter gives you everything you need to turn your favorite speakers into a wireless sound system for your smartphone and tablet. Multipoint Bluetooth connectivity lets you pair two devices simultaneously, and stream audio from either one — with a reliable connection from up to 20 meters (66 feet) away — to most powered speakers with standard analog RCA or 3.5 mm connections. Pairing your devices is as easy as pressing a button, and automatic re-pairing makes streaming hassle free. And you never have to compromise on sound, because the Bluetooth Speaker Adapter is tuned at Logitech’s state-of-the-art labs to deliver high-quality acoustics.
* Works with powered speakers with a 3.5 mm or RCA connection—PC speakers, home stereo system, or A/V receivers.
