Common problem

Q1: Why is the headset still connected to the phone after putting the headset back into the phone case?
Answer: Please check whether the charging box has power. When the charging box has no power, it cannot be turned off after placing the headset.
Answer: Please make sure that the headset is firmly fixed in the case, and the charging metal contacts and pins are clean. Try to clean the charging contacts between the housing and the Headphones with a soft cloth.

Q2: Why can only one headset work?
Answer: The wireless headset is in standalone mode and needs to be switched to pairing mode.
The settings are as follows:
Delete the paired headset information on the original device, press and hold the headset for 5 seconds to turn off the headset, and then press and hold for 10 seconds to restore the factory settings (the headset indicator will turn pink, that is, the reset is successful), and put the headset on Return to the charging case, and then open the charging case. Do not remove the headset at this time, wait for the headset to be successfully paired with each other (only one headset indicator flashes at this time) and then pair it with the Bluetooth device.

Q3: The headset cannot be charged?
Answer: Check whether the insulation label on the headset has been torn off.
