I have a pair of HD 25-1 and they're quite good. They're plugged in to my Cowon D2+ and I'm personally very happy with them. They offer excellent isolation and are comfortable to wear for about 2 hours at a time (afterwards they need readjusting).
Not sure I like the adidas branding, but the colours are cool!
