Pros:Very good sound, very comfortable, require little power, good bass.
Cons:The band keeps wanting to slide closed unless held open.
These extremely comfortable headphones really do a nice job with portable players, though they do have their limitations. Fortunately, most of the headphones that sound substantially better also cost substantially more.

The only thing about these that really irritates me is that the headband slides closed (smaller) under any sort of movement. I guess that's better than sliding open, but it's aggravating to slide them to a position, take a moment to disentangle the cord, and then find that the band has closed back to its smallest size. You need to get everything exactly right with your cords, amp, player, and so forth and THEN open them up and put them on your head.
I'm not generally a big fan of open-air headphones, since I usually use headphones when I'm mowing the lawn, traveling on a plane, or in other situations where I want to seal out ambient noise. And, since I own a couple pair of Grados, I don't use these in the house much, but where I can use them (on the beach, walking, kayaking) they do a great job and are by far my favorite headphones for the application.
