- The earbuds can only be used to control music players; some video apps may not respond.

- On a Windows computer, music playback cannot be controlled while the screen is locked. Please unlock and try again.

- Make sure you don't have multiple music playback apps open at the same time to avoid conflicts.

- Some devices may not respond to the earbuds' play/pause commands. Please try again on a different device.
