I just purchased Sennheiser's HD 555 maybe four weeks ago. Very popular at their price point. Picked up mine for $84 delivered. Break in period ongoing, initial takes; outstanding comfort, decent build quality, frequency separation very good; bass performance could be a tad better, excellent balance overall. I would not recommend them for travel or sports but that's up to you. For $84 bones, a steal... really.
