Although they claim to cancel 99% of ambient noise these headphones have almost nil effect in cutting down external/background noise. Tried two different sets in case the first one was faulty. Might as wel have been wearing a pair of light ear mufflers. Very disappointing in view of the manufacturers claims. Pity, as they appear nicely made and fold down well to go in the carry case. Not a patch on the Bose QC15, where you do actually notice a difference (but still not quite convinced they are worth the price tag). Still waiting for a set of headphones that actually does make aeroplane and background noise truly (almost) unnoticeable....
