Denon Headphones are always one of my favourite, previous models such as D2000 headphone and C710 earphone are what make my music experience different. They have exquisite design, from the Wooden D7000 flagship till AHD1100, these are the one falls into my "luxury" line of choice.
No doubt, changes are inevitable, recently denon annouced their new 11 models featuring IOS app integration.
Mainly designed for different usage, such as sport, airplane, audiophile etc.... which pre-designed IOS software for each of them.
What do they do? have a look in here engadget
