Find the cause step by step
- Look for the L and R letters on the headphones or cable and put each side on the right ear.
- Tap Left above. If it still comes out on the right, test the headphones on another device.
- Reversed on every device: the cable or plug was soldered backwards. A technician can swap the wires in minutes.
- Reversed only on the PC: open your maker’s audio app (for example Realtek Audio Console), look for “swap channels” or spatial sound options and turn them off.
Symptom, cause and fix
| Symptom | Likely cause | What to do |
|---|---|---|
| Reversed on every device | Wires soldered backwards | Swap the wires at the plug |
| Reversed only on the PC | Audio software or spatial sound | Turn off effects and restore defaults |
| Reversed in one game only | A game setting | Check the game’s audio options |
| L and R marks worn off | Worn on the wrong ears | Test above and mark the side |

Does Windows have an option to swap left and right?
Windows doesn’t have a simple switch for it. Some audio apps from the makers do. For music, some players’ equalizers can swap channels too.
How can I tell which side is which without the mark?

My Bluetooth earbuds sound reversed. How do I fix it?
Check that each bud is in the right ear (L and R). If they are and the sound is still swapped, turn off spatial audio or channel-swap options on the device and pair again.
