Not every entertainment system was born with Bluetooth connectivity. But that shouldn’t stop you from wirelessly streaming your favorite music to your system from your smartphone or tablet. The Harman Kardon BTA 10 external Bluetooth adapter enables you to stream audio wirelessly to the system from any Bluetooth-equipped portable device. HARMAN TrueStream technology means that the wireless audio connection will be the highest quality possible. The BTA 10 even has an LED light to show you when it’s searching for a Bluetooth-equipped device and when it’s connected, plus cables for attaching the adapter to your entertainment system.
