Sennheiser PXC 450, nouveau casque à réduction de bruit (The Bristol Show 2007)

Robert Follis, PR Guru for Sennheiser, gives us a world premier demonstration of the new model, the Sennheiser PXC 450 that is absolutely amazing. Get a little technical info, but we had here a live test. Often at the show seeing is believing, but here hearing is believing, and not hearing is totally convincing ! See these new £300 headphones in action !
