Replying to Help me pick Headphones

Let me just say first that I search the site, I just want some suggestions and info on my specific situation.

So, I have Skullcandy TI headphones right now, and there ok, but I want to upgrade to something with better sound. I have been looking around headphone.com, and have seen some thing I like but I would like to know more. I am looking for a pair of full sized or Earpad (supra-aural) headphones, less than or about $150. Also, I didn't like how bulky my Skullcandys were and would hope to get something smaller, and very comfortable. Some Earpads I liked are Grado SR 60, Sennheiser HD 25-SP, AKG K 81 DJ, Some full sized I liked are Sennheiser HD 280 Pro, AKG K 240 S, Ultrasone DJ1 HFI-500. Any suggestions between these, or other that are better than these in this price range. Any help will be appreciated.
