This helmet is an excellent product for both refined and efficient. Manufacturing is beautifully crafted for noise reduction headset comes in a beautiful leather satchel with among others an adapter plug for listening on an airplane. It's light enough balanced despite the discreet presence of a battery A4 (for the noise reduction function) in one earphone and perfectly covers ears while ensuring a secure fit on the head. Some criticize him perhaps to keep the ears warm after about 2 hours of listening but very tolerable sensation this is largely compensated by the pleasure derived from the acoustic quality and isolation (not total but effective) noise. With Amazon you can access a helmet very good original and refined look at an affordable and unbeatable price. I do not regret my choice on this article.
