Customer Reviews

pretty impressive
I have heard better headphones....they exist.
But I have never heard the music sound better when Im driving my tractor wearing my Sennheiser PXC 450's !!!
Altogether very impressive . Comfortable and they do knock back any background noise considerably .
As for a comparison with Bose...when did Bose ever make a hi- fi product ? Er never !

Sennheiser PXC 450
I purchased these headphones today for travelling & using around the home, as shortly I will be flying UK to Australia for a holiday & needed something to help endure the journey. So I did some research on the internet, & found that the Sennheiser PXC 450 came out on top. Tried them out & 5 star quality perfect sound quality along with being solidly built. I connected Sennheiser PXC 450 headphones to my Sony NWZ-A818 to enjoy listening to Dire Straits Brothers in Arms in sheer perfection & tranquility, as well as Kevin B****Y Wilson as I enjoy a good old fashioned laugh as well. I also love the talk through mode so you can listen to your favourite albums & talk to people directly at the same time. The headphones also have noisegard which really reduces background noise such as aircraft engines other peoples babies crying talking etc, I tried these out at home & I live within walking distance of the M1 & M25 & with everyday noises around the house these noises where greatly reduced with these headphones.
The Sennheiser PXC 450 also has a detachable cable so the Sennheiser PXC 450 can also be used as hearing protectors, only requires 1 AAA battery but 2 are supplied great for long haul flights. The Sennheiser PXC 450 also comes with 1 x 6.3mm stereo jack, 1 x in-flight (2 x 3.5mm mono jack & carry case. My only gripe is that the headphones are a little on the big side but this easily offset with superb sound quality so I am still giving the Sennheiser PXC 450 10/10.

Great headphones for work in noisy office
If you work in noisy office next to busy road and with lots of noisy computers and noisy people and you work requires concentration - these are headphones for you. If you usually listen to your favourite music while working you already know that wearing headphones few hours a day makes you a bit tired - Sennheiser PXC 450 solves this problem.
Noise cancelling doesn't cancel everything, don't expect any miracles but with these headphones you can listen to the music with much lower volume without being distracted even by somebody next to you shouting on the phone.
The sound is maybe a little bit to warm but this is just my personal preferences, apart from that sound quality is very good, not as good as eg. Sennheiser HD 580 but PXC 450 are not studio headphones. Battery life is too short, but if you use rechargeable cells it shouldn't be a problem. Even if battery goes flat simple switch to bypass mode and use as normal headphones.
I have got these headphones for about 3 months and now I cannot imagine working without it, these headphones become an essential tool like good quality PC display or chair which doesn't give me pain in my back. Since I got these headphones I come back home from work more relaxed and not as tired as before.
