Some minor knit-picking: one has to remove the cable from the headphones to get them into their carrying case. Not a fan of this. The Bose QC15s and Momentums don't need this to be done. I can play with them to to this, but its a hassle. Next, the iPhone control buttons are a bit too small and cumbersome to hit. Much easier on all my other portables. Sound wise though...they're very neutral. Just did a 30Hz to 18kHz frequency sweep, very balanced throughout without any glaring regions (or regions that are "MIA"). The bass is quite impressive and goes down pretty deep. Not overly efficient either. I need to play the volume a bit louder. No biggie though.
