Query: Great audio, noise cancellation so-so

Purchased these headphones due to pretty good reviews from both Amazon and tech websites. I am very pleased with the audio quality, especially for the price. I wouldn't recommend the headphones based on noise cancellation, however. This isn't a huge surprise, since these are a fraction of the price of the high-end noise cancelling headphones so don't let it be a deal-breaker if you are primarily looking for a good-sounding pair of headphones at a manageable price.
