This latest headphone by Sennheiser, the PXC 450, costs around $300, and this is the latest in technology. It acts as your normalheadphone, but with extra features. First of all, this headphone runs on a AAA battery, and that is like 20 hours of mind boggling music runs wild.

I got these specifically to filter out office noise listening to streams through my computer, as I'm a programmer in a farm of 6x6 cubes (about 25) with a lot of distracting noise. They accomplish that task well, and I am very happy with the sound quality.

Large price tag

Crutchfield has collected 30 user reviews for this product with an average rating of 4.6 out of 5 stars. The most recent reviewer said, "I bought these after a long struggle to choose between the Sennheisers and the Bose Quiet Comforts. I chose these based on reviews of comfort and overall sound.

These are the first jumbo sized headphones that I have ever bought. Previously I have had to replace the in-ear headphones every 4 months. This is because I tend to listen to my music at a fairly high level, and after a short time, they begin to produce a hissing sound when the base is high.

Superb sound quality

My get you a few looks on the train

Overall a very good product well made and attractive, very comfortable to wear for extended periods of time, sounds excellent and the noise cancelation works really well, also like the talk through function which I surprisingly used a lot, had it on a recent 4 hour plane trip with screaming kids...

Fantastic headphones with the best noise cancelling we've heard, but at a price. Audio quality is superb and the build quality will withstand the strains of constant use.

Price; Dance fans may want more bass; Noise-cancelling bypass switch instead of automatic cut-out

It breaks our heart to think of all the engineering Sennheiser did on the talk-through button on the over-the-head PXC-450s, because it works pretty well. You're just never going to use it.

The price I paid : 350Euro around £300 Sennheiser, that's the name I think of when someone happens to mention headphones. Synonymous with quality of production but most importantly quality of sound. These are an older pair of headphones I have these around Four years now.

Sennheiser as a company, has been around for years, and is definitely not a novice in making high-end headphones. If there are a pair of headphones you can compare the PXC-450 with then it would be Bose's QuietComfort 3. However, the PXC-450 outruns the QC3 with its features.
