I can get the RS220's cheaply for 218 euro (they're part of a reward program at my bank). Big difference compared to the MDR-1RBT's price of 350 euro. I like the design of the MDR's better, and the build quality looks top notch (Sennheiser's look a bit plasticky). Also prefer wireless over Bluetooth. Another thing that bothers me is that the RS220's apparently have a button on one of the sides that's purely cosmetic. Can anyone confirm/deny this?
I'm mainly interested in making this guy's - http://www.ronaldjenkees.com/ - music sound as good as possible.
Is this an easy decision? Someone give me a little push please! I can't really check them out 'in real life' as no local brick and mortar store seems to carry either model, let alone both.
