For much of my career my sanity on long trips was globally assaulted on marathon flights to Asia, the Mideast, or wherever, with layovers in sundry noisy airports. When Bose started offering decent NC earphones, I became addicted to the portable solace they provided and they were the best game in...

Great sound quality and super comfortable

The CNET "editor's" review of these headphones has completely changed my view of every ranking/ review on CNET in a very negative way. Everything he says is not just based on personal opinion, but completely opposite from my own experience.

Great Fidelity/ Great Noise Blocking

None

I bought this product a week or so ago,functions are easy to use,battery life great ,noise cancelling superb. Amazing sound, unique experience .... love music, treat yourself and listen to your Music your way ,no distraction. Awesome A+++

I've had these Sennheiser PXC550's for a few months now and I find them faultless. Firstly I bought them for a few different reasons, mainly I needed noise cancelling because I am very sensitive to unwanted sounds, noisy neighbours slamming doors, kids shouting loudly in next doors garden.

Tested these against the Bose QC 35 and Sony MDX's. Both good headphones but the Sennheiser's trump the Sony's for sound quailty and surprisingly, they offer better noise cancelling than the market leader in Bose. Battery life is exceptional and the CapTune app is phenomenal. Highly recommended!!!

These headphones are nothing short of amazing. First off, they look great and are super comfortable. The battery life is excellent and the wireless connectivity and functionality make them perfect for all aspects of use. But, most importantly, the sound quality is exceptional.

Very comfortable over extended wear with noise cancelling blocking out must external sound, no hiss on silent playback moments, quality first rate, easy to use especially when receiving calls, paired easily to iphone and Captune app easy to use to tune headphone to how you like to listen..

Absolutely love the product, the best and the service @BingLee was amazing. I tried the Bose headphones, and I believe the Sennheiser won hands down. I love the functionality of these headphones that you can have complete noise cancellation or not if you choose. Easy to use, fantastic sound quality

That's more of a statement than a criticism, though. While certainly rich, it errs just on the right side of overstated, and is careful not to slow rhythms or weigh down dynamics.Balance still favours the low-end through the wire, albeit there's a noticeable leg-up in refinement.It's not massive,...

Pleasing transparency for the price; Top timing; Clear and dynamic sound; Smart; minimalist design; Effective noise-cancellation
