Enjoy Wireless Music Streaming: This car Bluetooth adapter can connect to non-Bluetooth car audio systems, home stereo systems, speakers, and wired headphones via a 3.5mm AUX adapter; and equipped with a Bluetooth 5.0 chip, it can achieve a stable connection/fast transmission/wide signal range. Just pair it with your phone and start listening to your favorite music. Our Bluetooth audio receiver uses the latest CVC8.0 noise reduction and digital signal processor (DSP) technology, which can eliminate echo, protect against distracting background noise (like wind, traffic, or crowd), and provide you with clear call audio. Battery Life Up to 16 Hours: This helpful Bluetooth adapter can work for up to 16 hours when making calls or playing music. The Type-C fast charging cable (included in the package) can fully charge the device in just 2.5 hours. Moreover, this Bluetooth music adapter can be used while charging, which is very convenient. Hands-free Calls: The navigation features a built-in microphone and an MFB button to answer/redial/hang up/reject calls, helping you make hands-free calls. The Bluetooth audio adapter supports broadcasting voice messages from existing navigation applications. You don't need to look down at your phone while moving. Ensure your safe driving. The dual-connected portable Bluetooth stereo adapter can be paired with two devices simultaneously. You can enjoy your music and never worry about missing any calls. After pairing, as long as the Bluetooth device is within wireless range, the car receiver will automatically reconnect to the Bluetooth device you last paired with.
