5. How to switch the primary and secondary channel of the UTWS1?

A: 1. While left and right side of the earphones are turned on at the same time, the right channel will work as the the primary channel to pair the smartphone.
2. If the left and right channels are not turned on at the same time, the channel turned on first will work as the primary channel to pair the mobile phone.
3. During use, if the primary channel needs to switch, just turn the primary channel off, then the secondary channel will automatically convert to be the primary channel. At this time, it will work as one channel. When you turn on the other channel, it can pair autimatically.

Tips: since the primary channel consumes a lot of power, switching the primary and secondary channel during use can greatly improve the endurance ability.
