Hello, thank you for reaching out to Microsoft Q&A.
To better understand the issue, I would like to
- May I know if you're using a desktop or a laptop? and,
- Also, are you using wired or wireless headphones?
If you're using a laptop, how does the audio sound through the laptop's built-in speakers? Is the sound distorted there as well?
To check whether your headphones are the problem, try connecting them to another device, such as a mobile device, and see how the audio sounds. This will help us confirm whether the issue is with your headphones or with Windows.
If the audio is distorted on another device as well, then your headphones might be the issue.
