Step\/Method 1
1. Clean the headphone jack. Dip a cotton swab in alcohol, squeeze it clean, don't get too wet, insert the swab into the headphone jack, turn around and pull it out, repeat several times. Be careful not to break the swab with too much force. Or use a hair dryer and blow it away from the earphone.

Step\/Method 2
2. Sometimes the headset failure is not the cause of the phone's headphone jack, but the connector on the headset. Don't plug in the headphones at the end. Plug it in and check to see if the sound is better. If so, replace the headset to see if it works. Different wire sequences cause poor earphone contact. You should try replacing your headphones.
1. The charger is broken or the socket is in poor contact. It may be that the use of the charger for a long time makes the charger socket loose and the poor contact results in the inability to charge the Bluetooth headset normally. I suggest you try a new charger.
2, the Bluetooth headset battery is damaged, resulting in no charge. If the charger is good and the interface is not loose, it is necessary to consider that the battery is damaged. May be long-term use, resulting in battery aging, resulting in battery damage can not be charged normally, use.
