Volume is Too Low
- Confirm the volume is on by unmuting/increasing the output audio.
Weak or Unstable Bluetooth Connection
- Unpair the headphones from your device and forget them from the Bluetooth list. Then, restart both the headphones and the device before re-pairing them.
Debris or Physical Blockage
- Gently clean the left speaker grille using a soft-bristle brush, a dry cloth, or compressed air.
Faulty Speaker
- Remove the earcup & unscrew the screws inside with a Phillips head screwdriver. Then, remove the speaker and replace it with a new speaker.
