I am very interested in these two cans with plenty of base which I like.
What's the main difference between these (in bass, treble, highs). Is PRO 900 worth the extra cash?
I'm now using the portable amplifier FiiO E11 with a nice bass-boost with my Bose QC15 which doesn't has that much base but quite good clearness (but not for the money I spent on them)
So which headphone should I buy (the owners of XB 1000 and PRO 900)
