Love love love these - because I have very loud noisy (partying) neighbours and they were purchased so I could sleep at night. The only issue I have is that I cannot adjust it completely down to fit my very small head - at least I cannot be accused of having a "big" head. They certainly adjust well to the mainstream head size. I am trying a few ways to fix this, but otherwise they are brillian,t and work well for when I want peace and quiet during the day also from outside traffic noise.

Purchased for my son at school due to auditory processing disorder... it has helped him and the quality and case is great

Bought this for a plane trip. One set of batteries lasted more than 20 hours flying and they still going. Cut out 90% of the noise from the planes engines , voices not so effective but cut the voices down to about 50%. Puke this on with air plugs and turn the sound up you can almost completely drown the back ground sound out.
