These headphones offer excellent sound quality. The noise cancelling is not nearly as noticeable as for around-ear headphones, so that should be considered for those unfamiliar with the difference between the two varieties. The cord is perhaps a little shorter than one might expect, but not problematically so for all but the extraordinarily proportioned.

I have had these for over a year now and they are still just the best!!!! Can't believe that anyone would say these are uncomfortable. I purchased them because I cannot use the "ear pod" type of headphones!! The noise cancelling works so well that when I used them here at my house, I could not even hear the water running in my sink!!! (Kind of "freaked me out" at first) :) I mainly use them for running and they are a Wonderful distraction from how long or how far I have to run. I would definitely recommend this set of headphones to anyone!! Thank you Sony!! for such a great product!!

A great improvement on Sony's older Noise Cancellation device. This one indicated a 95% cancellation capability -- full marks for NO Exaggeration! Thanks. Was able to sleep soundly for the very first time on a noisy commercial airliner in economy class!

We purchased 14 of them for our computer education for many employees and they worked great. The employees couldn't hear us when we tried to get their attention and were startled when we tapped them on the shoulder. ONE QUESTION: Since we will have many people using them, we want to keep them sanitary. What is the best way to clean them without damaging the soft ear pads please? THANKS

Bought these to use while mowing lawn, block out the noise that was damaging my ears causing ringing. they work great. they adjust to conditions and all in all work great vs just ear plugs.

am enjoyed my new head phones, I would recommend them to my family and friends, and those who I work out with at the gym

So far very good. If my opinion changes, I'll let you know.

I received this product from work. The sound is very clear and I do not hear any outside noises.

Purchased a few of these on sale. I must say for the price the sound and noise cancellation are very good. I found them to be pretty comfortable and they are foldable for easier storage.

I've used many headphones in my 40 years, but these are by far the best. Not only are they fair at cancelling ambient noise, they make music sound amazing at the same time - enhancing both the bass and the highs. Flipping the power switch between off and on is night and day amazing. I'll never use non-powered headphones again. I even use them while I'm mowing to help kill some of the mower noise. These work great. I plan on buying another pair if I can find them on fire sale. -James
