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.

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.

Meet the Sennheiser PXC 450s, a set of mid-range active noise-cancelling over-ears that are not only super-comfortable, but block out a decent amount of outside noise. While they may not appeal to the most discerning audiophiles, they will absolutely give inter-continental travelers good sound and...

With $799 you can buy a lot of things. It can get you 2663 soft serve MacDonald's ice cream cones for example, or 53 movie tickets. It also happens to be the price tag for Sennheiser's latest and greatest pair of noise-cancelling headphones, the PXC450.

Great clarity; crisp sound; nice mid and treble ranges; great noise cancelling

Bass is a little weak; expensive

Sennheiser's PXC 450 noise-cancelling headphones claim to offer outstanding sound quality and optimum protection against ambient noise. At AU$799, they're aimed at a high-end consumer who's after terrific sound accuracy primarily when on the move, such as a business traveller - and those who are...
