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

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

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...

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

The superior sound quality and the comfortable design will allow you to listen effortlessly and quietly.

The lightweight design won't constrict your head; and the ear cups are plush and comfortable

Only 16 hours of battery life is less than other models; which can last up to 50 hours

Potentially crushing the BOSE QuietComfort headphones like a bug, the Sennheiser PXC 450 NoiseGard headphones are available for ?￡299 (or just over ?￡200 if you shop around) and boast 20 hours use on one AAA battery plus the ability to function as normal headphones when that 20 hours expires.

Expensive

Thank you for searching out Australian HI-FI Magazine's equipment review of the Sennheiser PXC 450 Headphones originally published in Australian Hi-Fi Magazine, July/August 2008 (Volume 39 Number 4).

I have this one from last 2 year's. Not using that much because it is big. It's give balance sound bass and tribble.

Clear sound balance sound

Bass is not that much
