I use UltraSone 580's as my goto cans when I'm at work or getting some coding done.
I have a pair of Beats Solo HDs, upstairs near the bed for late night listening on my tablet without disturbing the wife. Plus they are small enough I can hang them off the headboard without to much fuss.
My mother-in-law gave me a bunch of money a couple years ago for my birthday and Christmas.
I bought HD 600 earphones and I use them all the time for later evening TV and music.
I love those headphones.
chashint, I had the Senn HD-650s before I got the Oppo PM-1 and the PM-1 improves on every single aspect of sonics over the HD-650s! Yeah they are quite a bit more expensive, but they are one of the best headphones I've heard to date. Not to mention, they feel, and look incredible.
I looked at those briefly when shopping for some cans. Just a little rich for my taste at the time. Reviews seem to be universally positive. They definitely go above and beyond with the packaging on the PM-1's.
