Pros: The noise cancelling feature works well, and the sound quality is good. Lightweight and comfortable.

Cons: When using the noise cancelling feature, applying pressure to either side creates some sort of loud feedback squeal. It's impossible to use these when laying on your side. We returned the first set received, thinking it was an individual unit issue. The second set arrived, and we were very disappointed to experience the same problem. Looks like a design issue, not an individual glitch.

Overall Review: I do not recommend this item to those who enjoy laying down and listening to music. It is okay if the sides of the headphones do not experience any pressure.
