ANC works well, cutting out the growl of the bus, the rumble of the tube and the drone of office air-con. You can still hear talking and voice and announcements as you would expect.   PROS - ANC works well (so far: bus, tube, office) (to come: trains, planes, automobiles) - remote button works with iOS   CONS - earbud fit is awkward (they are prone to coming out of my ears with any tug of the cable) - charging light never goes off   NOTES - you really need to find the best fit earplugs (three sizes provided) - longer cable on one...

PROS - great sounding headphone - great in-ear fit - good quality cable - unobtrusive design   CONS - slightly heavy bass for me   NOTES Equal length cable for each ear (not for wearing behind the neck)
