The first: is the most common case, Bluetooth headset self-protection measures. Bluetooth headset if not used for a long time, then when we charge it again, it can not be charged at first, because the Bluetooth headset has not been used for a long time, the battery will be in a dormant state, at this time we need to charge the headset for 20 or 30 minutes of electricity, to activate the battery, at this time charging will not show the light, but in fact, it is charged. Wait half an hour and check again.

The second case: the contact of the Bluetooth headset or the thimble of the charging pod is broken - or the contact is poor.
Because the Bluetooth contact and charging bin thimble are often used, easy to damage or oxidation, it is easy to have poor contact, this time can only be taken to repair - if there is the same Bluetooth headset, you can cross test whether the earphone contact is broken or the charging bin thimble is broken.
