Recharge

First of all, choose a suitable charger.  Because most Bluetooth headsets have dedicated chargers, if you don’t have a dedicated charger, you can directly find the charging interface (some with a round hole, some with a MiniUSB universal interface) and use the same charger with the same rated output power.

Secondly, the charging time of general Bluetooth headsets should be kept within 2 hours, because too long charging time will directly cause the machine circuit board to age or even burn out, and various inexplicable machine failures, such as standby  Shortened time, frequent disconnection, shortened call distance, unable to turn on and other issues.  So, for the sake of your Bluetooth headsets, please give them a proper charging time.

Then, plug all the plugs in when charging, don't just plug in more than half, so long-term use will cause damage to the Bluetooth headset.  Of course, when unplugging the charging plug, don't be so big or rude, but be gentle, otherwise pulling the plug like this for a long time will cause the plug to become loose.

Then, when the Bluetooth headset is connected to the power source and charging starts, the red indicator light on the Bluetooth headset will stay on, indicating that it is charging.  If the charging is completed, the indicator light will turn blue, then the charger can be removed.

Also, when you want to charge the Bluetooth headset again, make sure that the previous battery is used up before refilling.

In addition, if the Bluetooth headset is plugged into the base or charging box for charging, compared to charging the Bluetooth headset directly, the power after charging will be more durable in use.  In addition, the charging method is the same as charging the Bluetooth headset directly. Align the charging cable with the hole of the base and insert it, and then turn on the power to charge normally.

Finally, after the charger of the Bluetooth headset is charged, remember to unplug it from the power strip. If it is plugged into the power supply for a long time, it will directly and seriously affect the life of the charger.

The above is all about the types of bluetooth headsets and how to wear them. Of course, the biggest advantage of bluetooth headsets is that we users can avoid the trouble of annoying wires and talk easily in various ways.
