I love these headphones and I highly recommend. They sound crystal clear.

After our last flight, my wife wanted to get noise canceling earphones instead of using earbuds. Not wanting to spend $200-$300, I opted for these for a Christmas gift. She loves them, says"they're perfect."

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

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

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

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

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.

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

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!
