Alright gang, I tried the HD-558's. The Pros were they are very comfy, well built, and for the money sound really good. The Cons were the open ear design had a surprising amount of bleed thru, and allowed a surprising amount of outside noise in, and the cord is about 9 feet long (I kid you not, the joker has a cord from here to China)...
Most Sennheisers are like that, I have a pair that my wife uses with the cable zip tied to about 3 feet. Sony's Pros are long, but are coiled to about 4-5 feet to not get in the way.
