With the Bluetooth cassette adapter, your cassette deck player instantly becomes a wireless Bluetooth cassette recorder. Use it in your car or home audio system. Stream music from any Bluetooth-enabled device such as iOS, Android smartphones, tablets, and other compatible electronics. 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. Enable hands-free calling, answer calls easily, and listen to audio clearly. Equipped with a Bluetooth 5.0 CSR chip for fast, stable pairing and automatic reconnection upon startup.
