4. Question: Why is there a delay in the video/game?
   Answer: Affected by the environment, network, and mobile phone codec speed, it will cause different degrees of delay when the mobile phone transmits audio data to the earbuds ; (Turning on the game mode will increase the power consumption and decrease the use distance. It is recommended to use the normal Bluetooth mode in a non-gaming state. When the real-time voice function is enabled in the game, the background sound clarity of the game will be affected because the current game software sets the Bluetooth transmission rate as the highest priority).

5. Question: Why does it get stuck/intermittent?
   Answer: When using the earbuds, if there are a lot of Wi-Fi connections, 4G signals, high-power electrical appliances, etc., interference will occur, and the earbuds may be stuck or intermittent; it is recommended to change the environment and try to pair the connection again.
