Since my Sennheiser HD280PRO had the right driver voice coil snapped right at the edge of the membrane, I must find another one for substitution. I can't find this exact model for my headphone on the internet, so I contacted Sennheiser to know if they have in stock. I could also buy a new set...

Recently, I purchased the new model 280 PRO. However, the noise isolation doesn't seem to be as good as the original model that my buddy has. Does anybody else feel the same way?
