Only singing into and using it for mic'ing guitar amps. It doesn't sound as bad at about 6 in away from the source and the issue becomes bearable to say the least. But when it is used for close up mic'ing like the manufacturer recommends, is when the distorted hiss really comes out. When I swapped it out for my cheapo radio shack dynamic mic just to check the source (the quality dropped significantly but the) the distorted hiss wasn't there. I also swapped out the cables and used the cables with a separate mic just to be sure it wasn't the cable. Also as a last resort I check the headphones on several sources to be sure that wasn't the problem either.
