Bluetooth 4.1 adapter-receiver is a universal device for wirelessly connecting your smartphones, tablets, and computers to car audio systems, home stereos, or wired headphones. With it, you can easily play music, audiobooks, and podcasts without cables, turning any speaker system into a modern Bluetooth zone.
The device is equipped with a built-in microphone, allowing it to be used as a full-fledged Hands-free system for safe conversations while driving or during household chores. The adapter’s body contains a battery, providing mobility and autonomy.
Furthermore, this receiver can be used as a wireless receiver for wired headphones — your phone or tablet can be up to 10 meters away, while you stay connected or enjoy music without restrictions. For easy carrying and attaching to clothing, a practical clip is provided on the body.
The adapter is fully compatible with iOS (Apple) and Android operating systems, making it an ideal solution for users of any mobile device.
How to connect the adapter in the car:
- Turn on the device and pair it via Bluetooth with your phone or tablet.
- Insert the adapter into the Mini Jack 3.5 mm port of your car’s audio system.
- Activate the music playback mode via external source (AUX/Line-in) on your car stereo.
- Control tracks and volume using the buttons on the adapter itself or directly from your device’s screen.
During incoming or outgoing calls, the adapter automatically uses the built-in microphone — provided that microphone access for Bluetooth devices is enabled in your phone’s settings.
