How's that better from sony xm4's 30 hr battery life?

We’d have to wait for reviews! I have QC35 but after listening to Sony XM4s, QC35 definitely feel inferior in terms of sound quality. However, Bose ones have contours within ear cups and physical button controls, both of which are much better than Sony.

So much costly 24,096

Yes the pricing at ~25k is definitely steep but having used it at home and during long travels (16 hour flights at times), these are worth every penny.
