I'm currently shopping for a new headphone that I'll be using all the time at home while I'm on the computer.  Comfort is important but I'm more interested in the best sound quality (with a slight preference to bass).  The trick is I'm only able to work  with a $50 USD budget.  After looking on my own I have it narrowed down to the following headphones.  Any suggestions, or help at all, would be very much appreciated.
