How can I remove a buzz of my helmet?
I took the black cloth and found a hair inside. After everything was back to normal. I have a supra-aural headphones, the ones who come and sit on top of your ears. I own a pair of Koss Porta-Pros. If some time and decided post, I found this solution on a forum, thought it might be easier for others to find it here. In addition, other solutions could help other people.
Coss? I think u better send to the factory because Koss won a lifetime warranty for their products
