This is a very good product for most of helicopter pilots who fly noisy equipaments like R22, with this headset you you' going to listen to the other occupant better even if he is not using the same model or another Bose headset, other good thing is that you listen to yourself much better with the advantage of the abatement of the outside noise, without loosing the nice sound of the rotor spinning, I strongly recommend this product!Have nice and safe flights!
