Why is it important to test your headphones?

The stereo experience is essential to enjoy music, movies and, above all, competitive games where you need to hear where the enemies' footsteps are coming from. This tool helps you verify:

  • Correct orientation: Make sure you don't have the headphones on backwards (the "L" should go on the left ear and the "R" on the right).
  • Sound balance: Check to see if one side is louder than the other (a very common problem when the cable is damaged).
  • Connection errors: Sometimes, if the 3.5mm jack or Bluetooth are not paired properly, the sound comes out in mono instead of stereo.
