I read that JVC HA-RX700 and DBI Pro700 headphones were pretty good in their price range. Can this be confirmed? And if this is true, which are better?

Thanks for the suggestions. I also was just reminded that I wear glasses (half the time) and have big (3 inches at their longest) ears; so that might be a factor? Portability isn't really a factor since i don't have anywhere to put them anyway, but iI don't want anything too bulky.

I am looking for some decent headphones for melodic death/progressive metal at a low price. I listen to bands such as soilwork, into eternity, disarmonia mundi, scar symmetry, dream theater, opeth, arch enemy, and other similar stuff. I use a zune hd, and usually listen on the bus or outside...
