That's nice, but the pair I heard failed to live up to the measurements. I've played both on one of the better smartphones for SQ, the Galaxy Note 2 w/ Neutron Player, and the Beats were unquestionably better. They also have below average comfort and a poorly designed headband which creates a pressure point on my head over long-term use.
If a company cannot release a £320 headphone targeted for portable devices without QC issues and basic ergonomics, they are entitled for criticism, just as surely as Beats were.
For the record, I use all of my portable headphones out of my iPhone/iPad or iPod directly.
