Bluetooth receiver for home stereo, speaker, headphone
In receiving mode: Whether at home or in the car, you can connect your mobile phone or tablet to speakers, amplifiers, or car stereos via a Bluetooth adapter.
WARM TIP:
Plug the USB charging cable into a 5V 1A power adapter for charging, do not plug the USB cable directly into the USB power port of your TV or computer, as this will result in an insufficient power supply. (Only one USB charging cable is included in the package, the power adapter is not included.)
And it will not work properly If the power voltage is 3.5V or lower.
