When I listen to vocal heavy tracks, I get this buzz/distortion in the vocals when they begin to sing pretty loud   https://soundcloud.com/keokio7/vocal-prob#t=0:06 listen to the part when she says "kneeling" theres a buzz.  You may need headphones to hear it     At first I thought it was...

So I got these headphones about 2 weeks ago and have been listening to them but have this weird buzzing / distortion noise from these headphones especially during vocal parts of the song   I tested it with my regular cheap headphones and have no buzzing   I also tried different combinations...
