I sought to find a suitable upgrade/replacement for my Bose QC2s. After a ton of research I came across these. Most reviewers state that the construction, noise canceling and sound quality beat the Bose older and current Bose models hands down. Having tried first hand I absolutely agree!

Very high fidelity - Noise canceling is exceptional (beats Bose without question!!!) - Sturdy construction/finish

- Carrying case fits the headphones perfectly, but there isn't room for anything else; - Noise canceling works so well that it seems to muffle audio output

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.

My previous headset was a Bose QC 2 and wanted to try a full ear cover noise canceling headset. The Sennheiser PXC 450 received enough good reviews for me to give them a try. Upon receiving them, the first thing that I noticed was a persistent low frequency rumble.

Volume controls; pause control; sound quality

Persistent low frequency rumble; P..; poor customer service from Sennheiser

I don't have much experience with noise canceling headphones, but after quite a bit of research I settled on these (it came down to Bose and Sennheiser). For a casual listener, these are amazing headphones.

Comfortable; Great Sound

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.

I purchased these to replace an old pair of Sennheiser NR phones I've had for about 15 years. While I liked my old ones these are far better both in design and operation. The battery is internal, the ear cups swivel 90 degrees for storage, they come with a case (a very nice case) and the cord is...

The PXC 450 is the latest from Sennheiser's travel line of headphones. "Portable" and "circumaural" generally don't see eye to eye due to bulk and issues with anchoring them to your head.

I use it for 2 years, and I'm not tired. Even if it does not offer perhaps the best "noise cancellation" of the market, it outperforms the competition in several ways. In particular, a remarkable musicality (this is a real headphone "audiophile" Sennheiser): no special coloring of the sound, not...

You will not be disappointed. Great quality, comfortable and nice long cord. Worth the money.

Good quality authentic sound headphones with reasonable noise cancelling, but buy rechargeable batteries and a charger.

When everything else is going right, they have great clarity of sound; Pretty good at noise cancelling without distorting the sound; Clear authentic sound is what I was looking for so they are quite good for what I needed

Very battery dependent and they go through batteries very quickly and won't work if the battery is a little low either; I'm having trouble with volume too which I believe is an impedance issue, so be sure to match your equipment
