The way to go with sound sealing noise cancellation headphones...if you can afford them.

Comfortable; great sound; superior noise cancellation

Expensive; poor packaging (check your pair first before opening

The excellent product, with amazing built in quality. Based on my experience I will suggest this phone whom is looking more for the music quality then for noice reduction as music is superb but cancelation is not as great as in BOSE QuietComfort 3.

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

The Sennheiser PXC 450s (MSRP $449.95) are an all-around, decent set of active noise-cancelers that don't sacrifice much performance in order to block out unwanted noise-and that's rarer than you'd think.

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.

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

Very good for both home and travel.

Great sound

Large price tag

I went back & forth between the Sennheiser and the Bose headphones. So far I am very pleased with these for overall comfort and sound quality. I have not used them in an airplane as of yet.

Sound Quality

Comfort; Not as comfortable as Boes

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...

Spectacular sound. Quality hardware. Low sound leakage. Talk-through is cool. Very satisfied. Going to start looking at amps to go with it too. Also, great customer service!!

Comfortable; Durable; Great Sound; Stylish

No cons
