Interesting recommendations guys. I've taken a look at the links in DrSheep's answer and checked out the Mad Dogs.   On the M-100s:     One of my friends has them and is happy with them, but I don't like their sound very much - their highs feel a bit tinny to me, but that's just my opinion...

Updates!   I've looked at some other options, such as the Sennhesier PXC 450 (currently on sale under my price range) coupled with the Fiio E17, which was recommended in reviews to combat the very high power usage of the 450's.   I'd really appreciate recommendations or tips!

Hi everyone,   I'll cut right to the chase: I'm looking for a solid pair of over the ear headphones for use in both my home and a possibly noisy office environment, as well as for use on public transportation. I care about sound quality, so I want my headphones to provide great sound...
