Use it in your car or home audio system to stream music from any Bluetooth-enabled device, such as iOS, Android smartphones, tablets, and more. No complicated installation required. No wires. No tangled tapes. Simply insert the adapter and it powers on automatically. Thanks to the built-in microphone, you can keep your hands on the steering wheel while driving, enabling hands-free calling. Answer calls easily and clearly while listening to audio through your stereo. Equipped with Bluetooth 5.0 and a CSR chip for fast, stable pairing and automatic reconnection upon startup.
