These are the worst for the money and will break. And Sony won't help.

Noise cancelling as in the noise will only come out of one ear in time. If you do get them dont wrap your cord around or it'll eventually happen. Not the most comfortable headphones but had decent sound for a while.

Purchased these at an airport with the hopes they would do better than my existing earbuds (without noise cancellation). The headphones turn on (power light is on), and there might be a little noise cancellation occurring, but it is so minor that you have to take the headphones off and put them back on to tell if there is a difference, and even then it is tough to say. I have had great support from Sony in the past, I hope they stand behind these as well.

Sounds good but stop working after 3 months. To bad.

I bought this two months ago for my son. He spent his own money on it. Yesterday, the prong broke off, rendering them completely useless! Cheap junk, Sony. I will not buy from you again.

These are not noise canceling, they are bulky and heavy on the head after 20 minutes. So basically, they don't do what they are advertised to do and they are uncomfortable. I will be returning.

They were good when they worked, but had only 3 months, before had issues with the wires. I don’t leave reviews right away, because sadly things aren’t made to last. It should last longer than 3 months though. The plastic seems like it would break easily, but that wasn’t the issue. The covering for the wires started to separate and they stopped working. Just look at the percentages. Having 10% with 1 star review should speak volumes, but I looked at the average of 4 stars. I figured Sony is a quality brand and would be a good buy. I was completely wrong. Lesson learned and would suggest you look for another pair with better reviews. Learn from my mistake and find a better pair.

Too small and didn't make a difference on the plane.

They are currently functioning as headphones. However the battery on the noise canceling portion lasted about 2 days

Stopped working after a few months of use
