This might be a strange request, but here goes.
I have the opportunity to get the Koss Tony Bennett Signature Edition for $80. I am ALL for trying before I buy, but I can't find a local store that I can demo them at. While I know that it really isn't fair to compare these to headphones that cost triple the cost, I'm going to ask you guys to do just that for me. I guess I'm looking to be talked out of them, but if the Tony Bennetts do anything that is DIFFERENT or excels in a particular domain relative to these other headphones, please let me know. I have seen some people say good things about the Koss cans, but I don't want to fuel my headphone addiction by buying stuff I'll just not use.
So if you'll please, can anyone shed some light on how the Koss Tony Bennett Sig Edition will compare to these:
Sennheiser HD558 (now foam modded)
