I LOVE the adjustable straps on the top. On the other extreme end, other reviews were stating the opposite. As others have written, the older version had fabric on the underside of the strap and the new design does not. Her shoe bed was wider and the thong portion on her shoe was leather. These feel comfortable, and there is definitely more sole/arch support, as well as foot protection from the enclosed toe area. Initial pairing was simple and automatic with my iPhone - place it next to it, turned it on, hit accept and done. Mids - A bit to high level for me, it tended to make punk rock music sound very close and muddiedLows - A bit boomy but very spaciousAudio Technica ATH M-50xHighs - Quite good representation, a bit cold thoughMids - Nothing special, no major issues thoughLows - Too over-emphasized-----------------Comfort---------------Beyerdynamic DT 770 - WinnerPerfect. They fit good I like them The hardwood floor always makes me worry about my little girls frozen feet in the freezing cold weather. That was hard to get use to.
