Bluetooth Connection Stability
Why is the Bluetooth connection unstable sometimes?
| Reasons | Workarounds |
|---|---|
| Case 1 When using the earphones close to personal computers, Wi-Fi routers, microwave ovens, refrigerators, etc. Refrigerators, microwave ovens, Wi-Fi routers, personal computers, etc. are devices that emit radio waves. The earphones may be affected by these radio waves when using them in a location with a mixture of multiple radio waves. | Please use the earphones away from Wi-Fi routers, personal computers, microwave ovens, refrigerators, etc. in order to avoid radio wave interference. |
| Case 2 When using the Bluetooth device in the pocket of the chest or pants, or a bag while listening to the audio. If the engine ear is diagonal to the Bluetooth device, it will affect the Bluetooth signal. As human body is the biggest source of signal blocking. | When put the Bluetooth device in a pocket or bag, move the Bluetooth device to a place where there are no obstacles between Bluetooth device and earphones (such as the human body) for Bluetooth communication. |
| Case 3 When using the earphones closes to the other Bluetooth devices. The earphones may be affected by these radio waves when using them in a location with a mixture of multiple radio waves. | Turn off the Bluetooth function of the other Bluetooth devices. |
| Case 4 When using the device away from the earphones, such as in a different room. Bluetooth communication gradually becomes weaker the further away Bluetooth earphones are placed from a Bluetooth player.When using Bluetooth earphones and a Bluetooth player in different rooms with the doors closed, Bluetooth communication may be weak. | Keep the Bluetooth earphones as close to the Bluetooth player as possible. |
| Case 5 When a lot of applications are running at the same time when use the Bluetooth function. | Quit apps which you are not using on the device to reduce the load. |

What should I do if the charging case won't charge?
Please try to use another known working charging cable to charge the charging case for more than 10 hours through your computer. (take the earphones out of the charging case when you charge it.) Compared to other electronics, the earphones are low power products. Hence for charging safety, please do not use fast charger.

Does the earphones not use for a long time without charging cause the earphones not to turn on or the battery to drain quickly?
Earphones left uncharged for a long time may indeed experience some degree of battery degradation. Even lithium-ion batteries, if left unused for a long period, may encounter the following situations:
- Battery self-discharge: Batteries naturally discharge even when not in use, which is determined by the chemical properties of the battery. If left uncharged for a long time, the battery may gradually lose charge due to self-discharge.
- Battery aging: Over time, the chemical components of the battery will gradually age, leading to a decrease in battery capacity, even if it has not been used.
- Deep discharge: If the battery remains in a low-charge state for a long time, it may enter a state of deep discharge, which can accelerate battery aging.
To maximize battery life, it is recommended to periodically charge earphones that are not used for a long time, avoiding leaving the battery in a completely discharged state for extended periods. Additionally, it is best to store the battery with about 50% charge and keep it in a cool, dry place, avoiding high temperatures and humid environments.
Please try the following steps to see if there's any possibility of repair:
- Connect the earphones to a computer and charge them for 10 hours;
- Reset the earphones.
Why the battery life of the left and right earphone is inconsistent?
Generally speaking, the main earphone consumes more power. The difference may be within 10%.
Why the battery life of the earphones does not match the product page promotion?
The product promotion page includes the duration of a single charge of the earphones and the total duration of use with the charging case. The battery life of earphones is related to volume and Bluetooth encoding.
Why the earphones do not charge or the volume decreases after being exposed to rain?
The earphones support waterproof. After encountering water, please dry the earphones with a hair dryer (use cold wind) and clean the charging port in a timely manner to ensure a dry environment before putting them into the charging case.
