Headphoneus Supremus
The best bang for money in this price limit is ATH-A900X. It is in a different league from the headphones that you mentioned. Do not get any of those.
I would agree that the A900X are excellent headphones for the current price. But sounderhd is looking for portable headphones. The large bulky size of the A900X would make them a poor choice for portability, and I would worry about the wing system being damaged unless one has a very good case for them.
