With the Bluetooth cassette adapter, your cassette deck player instantly becomes a wireless Bluetooth cassette player. Used in your car or home theater system. Stream music from any Bluetooth-enabled device (e.g. iOS, Android-based electronics, tablet PC, etc.). No complicated installation. No wires. There are no tangled or tangled ribbons. 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, answer the call easily and conveniently, and listen to the sound. Install version 5.0 of the Bluetooth CSR chip, quickly and seamlessly connected, and automatically reconnect when booted up. A blue/red flash indicates that the 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 cassette adapter contains a long-lasting battery, which is suitable for long trips. The Bluetooth function allows you to listen to music while charging, as the charging port, on/off button and microphone button can be placed outside the cassette deck.
