I have alpha bass headsets and recently noticed that one of the headsets sounds blown out. It rattles and has very poor sound quality at any volume setting. I tried switching out he cords but that didn't help. I also tried it on multiple plugs and nothing changed. They could have been like this for a while and I didn't know because the pair I use is working fine. They are over three years old in like new condition, other than this issue. Is there a way to get them repaired?
