FreeBuds Pro is a true wireless Bluetooth headset released by Huawei on September 10, which has a 580mAh battery built into the charging case. Recent online disassembly shows that it is not easy to replace the battery of this charging case.
The charging box is fixed by two ways: clip and glue, so it is difficult to open the cover. The internal structure of the charging box is complicated. The plastic fixing bracket at the bottom can only be removed by removing the screw.
