Wireless charging audio is a kind of audio that can be charged wirelessly and is very convenient to use. First of all, the speaker needs to be placed on the charger that supports wireless charging. When charging is complete, music can be transferred from the phone or other device to the stereo via Bluetooth or other wireless connection. In addition, you can also control the volume, track, pause, and play through the buttons on the stereo or the remote control. During use, it is necessary to pay attention to keeping the distance between the sound and the connected device not too far to ensure signal stability.
