TROUBLESHOOTING

Why is the Bluetooth connection unstable sometimes?

	Reasons	Workarounds
Case 1	When using the headphone 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 headphone may be affected by these radio waves when using them in a location with a mixture of multiple radio waves.	Please use the headphone 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 putting the Bluetooth device in a pocket or bag, move the Bluetooth device to a place with no barriers between the device and headphones (such as the human body).
Case 3	When using the headphones close to the other Bluetooth devices. The headphone 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 on the other Bluetooth devices.
Case 4	When using the device away from the headphones, such as in a different room. Bluetooth communication gradually becomes weaker the further away Bluetooth headphone are placed from a Bluetooth player. When using Bluetooth headphone and a Bluetooth player in different rooms with the doors closed, Bluetooth communication may be weak.	Keep the Bluetooth headphone as close to the Bluetooth player as possible.
Case 5	When a lot of Applications are running at the same time.	Quit APPs which you are not using on the device to reduce the load.

How to connect the headphone with two devices at the same time?
