Sennheiser PXC 450

I use it for 2 years, and I'm not tired. Even if it does not offer perhaps the best "noise cancellation" of the market, it outperforms the competition in several ways. In particular, a remarkable musicality (this is a real headphone "audiophile" Sennheiser): no special coloring of the sound, not like listening to a pair of cans. The possibility of using 100% passive (no battery, a rare feature on this type of headphone) is really convenient, and makes it a truly versatile headset. The headphone is also remarkably comfortable, it can be used for several hours without fatigue, which is important airplane. I had the opportunity to sleep with the ear, without music, just noise function: the top plane. The "talk-through" system also works very well (handy when the stewardess came to ask you if you want tea or coffee Finally, it is foldable and comes in a small carrying case that provides rigid adequate protection. It is not given, of course, but given the quality and scope, the price seems right to me. In short, if I had the choice again, it would be eyes closed.
