I recently had an unfortunate mishap where my cat damaged my wired headphones. While waiting for a new pair, I decided to connect my wireless headphones via Bluetooth to my computer. They connected successfully, but the sound quality is terrible—crunchy and flat. I've used these headphones with my phone before, and the sound was crystal clear, so I don't think the issue lies with the headphones. Additionally, my Bluetooth speakers work perfectly fine with the computer, which makes it puzzling why these headphones sound so awful. I'm confused because all the individual components seem to function well—what could be causing this problem?

Make sure to check your Bluetooth settings. Many headphones default to a lower quality output if they have a built-in mic. Disable the microphone in the device manager or under "more sound settings"; this might improve your audio quality significantly.
This might be a codec or profile issue. Sometimes, Windows switches to a lower quality codec for Bluetooth audio. You can check what codec your headphones support versus what’s currently being used. Tools like Bluetooth Tweaker can be helpful for this. Also, try removing and re-pairing the headphones; that can sometimes fix weird audio issues!

I found that my computer is detecting a nonexistent microphone associated with the headphones, which is odd since I'm not using one. Any advice on how to disable this without any actual hardware?
