Baseus W06 Pro Wireless Earphones. Two earphones have only one sound. What should I do?

Disconnect the device on the phone first, and then both the left and right ears should be restored. Open the cover and take out the headset. Tap the touch position of the headset three times, then press and hold the back of the headset for 10 seconds to reset, then put it in the charging compartment and wait for 5 seconds. Then take out the paired connection again.
