I have both the Studios and Bose OE2. My girlfriend also has the AE2. In my opinion, the Bose are MUCH better in terms of sound quality and comfort. I haven't used my beats for ages...
To be honest both the Beats and Skull Candy are shit. They are made for style and not for comfort or sound quality. The sound you get out of a pair of Bose is so much better for the same price.
