These are full sized headphones but are 32 Ohm and easily driven by portable players. You probably wouldnt want to wear these around town but are great for home use.
Sometimes more expensive isn't always better as the 485's are designed for a little more full bodied (warm) sound as compared to the reference headphones.
Some of the good points:
-excellent sound even at very low volume
-excellent, tight, clean sounding bass, for headphones (midrange and treble are also outstanding)
-very comfortable fit. Open style, full sized that covers entire ear.
-comes with a heaphone holder which can clamp to a desk or shelf and makes for a nice place to put your headphones.
Negative:
-not really a negative but since they are open style, sound escapes them so you probably wouldnt want to listen to pr0n in public with them.
I'm impressed. If you have a portable MP3 player with quality sound (like the Creative Zen Vision!), you might want to check these out. They are exceptional at creating a soundstage and trance music sounds amazing on them.
I listened to my Hackers soundtrack to test them out. My reference song, Halcyon, On & On sounded great. I uncontrollably started to dance listening to Prodigy's Voodoo People and then settled down to enjoy Heaven Knows by Squeeze. You really do hear more music with quality audio equipment. I could hear lipsmacking and one backup voice for a choras I didn't know was there before.
These are also excellent for gaming due to their spatialization properties.

The important things for me in a headset would be:
-comfortable fit for long wear
-above average bass (but remain tight and clean sounding)
-good soundstage
For $79.00, I'm more than happy as I would have spent double or triple that for headphones to get quality sound.
As with speakers, headphones are personal preference so you never know.
