So this is the headset I’ve used for about 2 years now and I haven’t had a single issue. I was using it this morning like usual, then came back this afternoon/evening and my audio now isn’t as clear almost like I’m in a tunnel. 

I’ve played around with the audio equalizer but have had no luck in getting it back to how it sounded previously (crystal clear). 

If anyone has a solution it would be greatly appreciated.

Thanks!
