Well, I was surprised at the quality of this product. I watched a review of this product on youtube, but he didn't really have real-life experiences, he tested the noise cancellation in his studio and said that it was ok. So, I wanted to share my recent experience with others.
I recently traveled by plane and I have to say, the noise cancellation was pretty darn good if fact for me excellent. The sound, while watching a movie was awesome. The only downside is that they are a bit heavy, so when considering this product think about your neck. Also, the cushion part of the headpiece although very good needs a bit more cushion, just because of the weight. They also might be a little cumbersome for anyone with a small head.
I hope that helps you for anyone considering in purchasing these headphones.
