I gave in and bought these as the price point had come down far enough for my liking! £164 for a Bluetooth Headset with decent ANC is very nice and is now in the sort of range of Plantronics offering.
I've only had them a few days and the ANC doesn't seem as crazy good as the Purity Pro's I had previously but it's good enough to drown out Office AC and other consistent background noises. It's not strong enough to drown out people taking though.
Looks: I thought the black version looked a little too boring while the White/tan colouring in my opinion looks very nice.
Controls: So on the right side there are touch controls. swipe the cup forward / back and the track will skip forward / back (Although I found this didn't work on play.sportify.com ). Up / Down will control the volume which works pretty damn well for me.
