Kindly check these headphones with another laptop or IPOD and check if that works fine or not?
If this issue started occurring after doing some recent software changes on your computer, then I would suggest you to restore your system back to a date when it was working fine. System Restore will affect Windows system files, programs, and registry settings only.
I would also suggest you to run the Microsoft Automated Troubleshooter for Audio Issues, by clicking on the URL mentioned below:
Kindly revert and let us know the status.
Thanks & Regards
