Wow...This is an outstanding Noise cancellation Headset in the market which is available..I had a chance to try out the headphones and I am Stunned....would love to own one soon....

Keeps triggering music when I do not want it to, as the side controls and the on-off setting with the ear pad placement is too sensisitve.

An already well-functioning model has been updated with variable noise reduction and voice control. The user interface, on the other hand, has become somewhat messy.

The sound is among the best on the market, and the noise reduction works smoothly. Comfortable fit, without taking up too much space in the luggage.

The new features seem a little ill-considered. The combination of microscopic buttons and a jumble of hand signals makes steering more difficult than necessary.

When i opened the box thought these look like a nice pair of headphones. However thats where our love affair ended. The Pros Look stylish and seemed to fit well on my head and around my ears.

I tried on all the headphones at B&H (that were between $100-300 and weren't ugly or heavy), looking for noise cancelling and decent sound impedance. No headphones fully or even decently impede external noise from talking coworkers. But this one was better than others, including Bose Quiet Comforts.

The list of excellent wireless headphones that also provide stellar noise cancellation is a short one, but things are turning around. Earlier this summer, Bose introduced its first wireless QuietComfort option, the QuietComfort 35 .

Powerful, adjustable audio performance with rich bass depth and bright highs; Excellent noise cancellation circuitry; Includes a detachable audio cable for passive listening; Exceptionally comfortable

Control pad is easy to misfire in certain modes; Possible to accidentally power the headphones up or down because of swiveling earcup controls; Digital signal processing is not for purists

With top-notch sound and whisper-soft noise cancelling, the Sennheiser PXC 550 puts Bose on notice.

Rich; balanced; and detailed sound; DSP effects offer powerful bass when you want it; Sennheiser's best noise cancellation yet; Sleek; portable design; Automated controls

Awkward switch locations; Noise cancellation doesn't quite match Bose; Pricey

The Sennheiser PXC 550 are wireless headphones with active noise cancellation, and go up against the Bose QC35 we reviewed and loved recently. This pair is a little more expensive at ￡329, but also offers a slightly more serious sound.

Great sound quality; Immense features roster; Effective; customisable noise cancellation

ANC bettered by Bose; Expensive; Very slight hardness to mids

These Headphones are something quite special. The Sound quality is absolutely fantastic for all types of music. They Look very stylish and fit well on both my head and my ears. The bluetooth connectivity is quick and doesn't lose connection like some other headphones I have had previously and also...

Shure, Bose and Sony rule the top-tier segment in the audio market, and so does Sennheiser. And when you think of noise-cancellation headphones, Bose, naturally comes to mind. Sennheiser, however, hopes to change the status quo, with the PXC 550 - the company's brand new wireless headphones with...
