AE2 isn't too horrible IMO. I tried them. Certainly not worth $150, but worth $60-$75 to me.
They're worth a little more to me because of how small and comfortable they are. I've yet to find another headphone as comfortable, as small/light and doesn't need an amp. Only one that comes to mind is the Maxell DHP-II and the Beyer Dynamic DT-235 with circumaural pads.
I'd use my KRK, but they not suitable for exercise.
Don't hate me, but I prefer the AE2 to the Creative Aurvana Live. I compared those side to side last week. Weird. Guess the AE2s more neutral signature is more to my liking. Yes, the AE2 is quite balanced and neutral sounding!
It's strange how the last time I had the Aurvana Live I liked them quite a bit and now I don't? I guess I'm gotten way too picky or my preferences have changed?!
BTW I did hear the OE2 (that Best Buy sells for $179!!) and didn't like them, but I only heard the display model. Sounded kind of muffled.
Now if I could ever find the AE2 for $70, I'd buy them again. No way ever they're worth $150. $100 max. I could never use the AE2 as a main headphone, but for exercise and as a portable with limited use, it's not too bad.
