generally speaking, a bluetooth headset is just a playback device, and the action of controlling playback is on devices such as mobile phones. There are two reasons for this:

1. There is something wrong with the setting of the music APP itself. Compared with this, the APP is the default player of the mobile phone, and the Bluetooth automatic playback function is set, so this function can be turned off.

2. There is a problem with the Bluetooth setting of the mobile phone. Generally, the Bluetooth setting of the mobile phone will have the function of connecting to start playing, so just turn it off.
