Sound only on the left ear?

I connected my scuf impact to the PC and wanted to play a game of Fortnite. Then I realized that I only heard the sound in one ear. Can anyone help me?

Could possibly be a loose contact. Try to move the ends of the cables slightly. If it does, it is very likely a loose contact.

If you can make sure by another headphone that it is not your PC, best, if available, take advantage and send back.

I'll try it Thanks for the tip.

It is not on the headphones): Thanks anyway for the tip
