Depends what sort of music you like.
I thought the Bose AE2 was awful. I had the original Triport, and have heard the AE. In effort to appease hifi types, bose gave the AE2 a flatter response curve, which is fine for some music. If you like Dance Rock or Hip Hop however, they come across as a bit weak in the bass department.
I found the OE2i to have a much nicer bass (but not in a daft exaggerated way like the Beats and the Klipsch cans I demoed) for the music I listen to, but ymmv etc. Haven't listened to the other cans mentioned.
