The Bluetooth signal is transmitted wirelessly, and the signals can be affected under the following conditions, resulting in a broken sound of the earphones: the distance between the earphones and your Bluetooth device is at the edge of the Bluetooth pairing distance. The transmitted signals encounter obstacles or blockages of the human body. Nearby are powerful electronic devices. There are other Bluetooth devices that are turned on and off nearby. To restore the stable connection between the earbuds and your Bluetooth device, avoid the above conditions and perform the pairing again. Why is the sound sometimes not clear/consistent? Connection is not stable. Why is the charging time of the left earphone longer than that of the right earphone? There may be differences in the use of the left and right side, resulting in an inconsistent charging time. In addition to this, the left earpiece is the main earphone. Some LED indicators and voice prompts are done by the left earphone, which can also lead to an inconsistent charging time. Package contents: wireless earphones: 1 pair (left and right). Charging case: 1 ear tip: 3 pairs (large, medium, small). Charging cable: 1
