Any one use the Panasonic RP-HD10's?

My dad got me a set of the Panasonic RP-HD10s, and right now there the best headphones I've got.

I use them with the Behringer XENYX Q502USB pre-amp, compressor, mixer, usb audio interface, that is plugged in via usb to my pc.
And I'm not an audiophile but my dad is and I just wanted some I put from other users of theses headphones and how they stack up with other head phones of there price ($350NZD)
