Bluetooth headphone circuit board may be hot for a variety of reasons, the following are some possible reasons:
1. Overuse: Using Bluetooth headphones for a long time may lead to overuse of the circuit board, and then heat.
2. Charging: When charging, the Bluetooth headset circuit board may be hot, this is because the charging circuit needs to consume energy, there is a certain heat release.
3. Charger problem: The use of an inappropriate charger or charging cable may cause the Bluetooth headset circuit board to overheat, thus burning.
4. Fault: If the Bluetooth headset circuit board fails, it may cause the circuit board to over-heat, thus burning.
Please note that if the Bluetooth headphone circuit board is excessively hot, it is recommended to stop using it and allow it to cool for a period of time. If the problem persists, you can contact the manufacturer or after-sales service center for repair or replacement. At the same time, using the appropriate charger and charging cable, and following the correct use method, can also reduce the case of Bluetooth headset circuit board burning.
1. It may be that the battery is insufficient, affecting the charging speed and short use time;
2. It may be that the quality of the battery itself is not enough, resulting in fast discharge of the battery;
3. There may be a problem with the circuit board of the Bluetooth headset, affecting the charging efficiency of the battery;
4. It may be that the battery of the Bluetooth headset consumes too much power, which causes the battery to discharge quickly.

Incorrect placement of components Some high-power devices require natural or forced ventilation in order to dissipate heat. If there is no proper airflow heat dissipation, the PCB will accumulate most of the heat, resulting in an increase in temperature, which will lead to reduced circuit performance or damage. It should be noted that sensitive components should not be placed near components that emit large amounts of heat; With proper heat dissipation and natural or forced cooling, the temperature can be kept within a safe range.
It may be that the rechargeable battery of this Bluetooth headset is broken, it may be that the circuit board inside is burned and short-circuited, which will cause the charging heat to open the machine. Can only go to repair. First change a charger to try, if the fault still exists is the earphone problem. If it can be turned on, it will not be used for a long time, or the battery cell is damaged and needs to be replaced. If it cannot be charged at all, it may also be that the charging current control circuit is damaged. Take the invoice and replace it after sale.
The main reason for this is that the Bluetooth battery has been damaged.

There are two possible solutions:
< br >
First, get the after-sales network of the Bluetooth brand to help check whether it is maintenance or battery replacement.
< br >
Second, get a special place to sell Bluetooth, they are connected with the maintenance of Bluetooth, maintenance costs are cheaper than brand after-sales outlets, but the quality of repair is not good brand after-sales.

When using a Bluetooth headset, you can use Bluetooth correctly according to the use of its manual, and improper use will cause Bluetooth damage in advance. When the battery product is not in use, it should be charged frequently to keep the battery power to avoid damage.
1. The Bluetooth headset will heat up when used for a long time, but the temperature is not too high, it is recommended to stop using when it is hot (change to external mode) to avoid damage to the headset and battery.
