Please don't get Beats or Bose. The sound quality of those is comparable to headphones that are less than $50...
You can look into Beyerdynamic DT1350 or Sennhesier HD-25 II. Both are light and portable, and just a little less than $300. Not sure if you are planning to use them at home or on the move, but you can also look into some of the IEMs (in ear monitors).
