Denon AH-D510?

I found only a few review about Denon AH-D510. I had a AKG518LE, but it is really too tight, the sound is ok. And I am also looking for something can fully cover the ears, rather than on ear. I tried Denon AH-D510 in a shop, bass is not as much as 518, still quite enough. 

but wanna try to have some more advice.

MP3 : SOny A828, Fuze

Pop, pop rock

MP3 320 files mainly

how does it compare with Denon AH-D310? JVC M750? Creative Aurvana Live!? 

or other suggestion?

Thanks

Thanks dweaver;

but the cable of HP700 makes me not bringing it outdoor.

so that is why I go to D510

Actually, I love the sound from my 518le, but I am looking for similar portablility but more comfy.

Budget is about HKD1000.
