Agree or disagree, Sennheiser HD 650 headphones are completely worth the $350 price tag on Amazon.com? I'm considering to get these headphones when I have the money. I recently got the Sennheiser HD 428 headphones and was disappointed to find that my JVC aircushions were ten times better. Thanks for any opinions! Oh and I'd appreciate Chungsters thoughts on the matter Please Register or Log in to view images I know he's in love with those Grado headphones..
