With the Bluetooth Cassette Adapter, your cassette deck player instantly becomes a wireless Bluetooth cassette recorder. Used in your car or home system. Stream music from any Bluetooth-enabled device (e.g. iOS, Android-based electronic devices, tablet PC, etc.). No complicated installation. No wire. There are no tangled or tangled bands. Just open it and it will open automatically. Thanks to the built-in microphone, you can safely place your hands on the steering wheel while driving, activate the hands-free function for mobile phones, easily and conveniently answer the call and listen to the sound. Install CSR Bluetooth chip version 5.0, quickly and seamlessly paired, and automatically reconnect when booting. A blue/red flash indicates that pairing mode has been activated. After successful pairing, the blue light flashes every 5 seconds, which has the advantage of longer distance and lower power consumption. The Bluetooth band adapter contains a long-lasting battery, suitable for long journeys. With Bluetooth function, you can listen to music while charging, because the charging port, on/off switch and microphone button can be placed outside the cassette deck. Package Included 1 x Bluetooth Cassette Adapter
