Excerpt: 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. If you guys are seriously looking for a good pair of high-end headphones, and somehow get smitten by the product on the basis of its features and performance, do make it a point to go through my...
Excerpt: These teutonic ear-coccoons will provide you with the long-haul comfort you so crave from a set of headphones. But can Sennheiser supply the audio excellence to complement the aural massage that the PXC 450s give you?
Pros: These noise-cancellers from German can-meisters Sennheiser quell background sound, from jumbo jets to buses, more effectively the any other headphones. The design is endlessly comfortable, even if it does make you look dorkish in the extreme, and it runs on a single AAA, so you don’t need to worry about recharging. Sonic performance is generally very good with reasonably well extended bottom end and very good mids and highs, without ever sounding harsh.
Cons: Reviewing audio gear is a very subjective thing, but there is perhaps something a bit I too I pristine about the PXC 450′s sound. It’s a little like being serenaded by the Pod people from Invasion of the Bodysnatchers – uncannily accurate but lacking in warmth. Although we’re not trying to imply the Sennheisers want to consume you and turn you into one of them, let us stress.

Summary: Offering the best noise cancelling out of any pair of headphones we've heard, Sennheiser's PXC450 offer a great choice for frequent travellers; just make sure you can charge the hefty cost back to your company.
Pros: Great clarity, crisp sound, nice mid and treble ranges, great noise cancelling
Summary: 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. No air hostess is ever going to believe that you can actually hear her asking whether you do, or do not, want some hypo-allergenic snack crackers, unless you take them off. World class sound Thankfully, the other functions on these Bose-bashers are much more sensible.
