sennheiser pxc 450 headphones

For a frequent plane traveller such as myself, the noise during the flights is really loud and when i add the volume of the music or the volume of the tv the sound gets to a deafening height. After a while my ear drums will start to hurt, because there is so much pressure being put on them. But not anymore. Just last week i bought a pair of Sennheiser headphones, pxc 450, and i took them on my last flight and not only was it quieter when i watched my movie, it was also a lot more comfortable then any other head phones i have used and the sound quality was marvellous. The pxc 450's have NoiseGard 2.0 installed in them so that it cancels out other sounds outside (such as the engine of the plane) so as to make it clearer for what i want to listen. They are the best set of head phones i have ever bought!
