I've had Bose noise cancelling headphones (QC3) for some years now. I've used them on many flights and never noticed any noise reduction. The up side is the sound quality for music is outstanding though.
Anyone tried these .....Tork Xpro...http://www.ebay.co.uk/ulk/itm/331429544688 http://www.ebay.co.uk/ulk/itm/231558761957
The web page says "Coming Soon" so I guess I will have to remember to look again in a few years time when they finally release it.
