Excellent noise reduction,
I bought my PCX450 headphones for use on long-haul flights, and they served me very well. The earmuffs were comfortable even after several hours' use, and the noise reduction enabled me to sleep despite typical aircraft cabin noise. Battery life was very good on a single AAA cell and the construction quality is excellent.
I have only two minor criticisms. Firstly, the audio quality is somewhat lacking in treble response. This is fine for my 57-year-old ears, but some listeners may find the audio rather too 'mellow' for their liking. And secondly, the cable is very durable but appears to be 'screened' electrically, as my Walkman radio/cassette found it hard to produce a noise-free FM signal when using the Sennheisers, although it worked perfectly on its own in-ear 'phones. For users of iPods and CD players this won't be an issue, but for radio users the headphone cable forms the receiving antenna and you may get hissy reception if the FM station to which you are tuned is not strong.
