They say it’s better to be safe than sorry. Before applying safety measures, it’s good to know what usually causes bluetooth headphones only work on one side. If your wireless headphones only working in one ear, it might be that:

  • there’s a dirty or faulty aux socket in the headphones
  • there might be a connection issue
  • you have plugged in jack before turning off Bluetooth headphones
  • you are accidentally playing mono sound which is programmed to play on only one side of Bluetooth headphones
  • one of the small mechanical triggers in the aux port of your headphones is stuck in a halfway position, thus telling your speakers to function via aux cable
