Query: Great noise cancelation, bad sound quality.

This headphone cancel out alot of sound especially on trains, buses, and airplanes. I liked this product but the sound quality is not worth the price, you can get a headphone that sounds a lot better at this price. I'd recommend this product only to people who like to travel frequently, and if you're looking for sound quality go buy the HD 595 or other non noise-canceling headphones. thanks for reading.
