Comments about Sennheiser Sennheiser Hd-555 Open-aire" Dynamic Audiophile Headphones (sennheiser Hd555):

I was initially worried about power requirements for decent sound. My iPod has plenty of power to drive these and so does my computer. They are very comfortable for wearing hours at a time. They have great range and the bass is great. I listen to mostly electronic music and I'm impressed with the sound. For the money hands down the best set of headphones I've ever owned. My one suggestion for improvement is to have the 3.5mm connector be the default and that the connection adapter become the 1/4in one. Otherwise there isn't much flex at the connection point for small devices. I think there is a kit for this somewhere.
