The headset does what he should. It suppresses the noise in aircraft. When you turn on the noise reduction you notice audible difference, which facilitates me sleeping on the plane. The remaining noise is attenuated but not suppressed. In Cubicle you hardly notice the noise reduction, it's also a noise reduction and no noise. The sound is good, and to use really in the area such as aircraft interior. Audiophiles will always have something to complain, maybe it's the wrong product for this application. Battery life is fine. In addition, you can still listen to music and the damping is still okay without battery. In very warm flights can ever warm hot on the ears, but that's due to design. The headphones around the ears. The inclined frequent flyer is perhaps better served by Bose, but for the average flyer to the noise the value for money is good and annoying to recommend the product.
