The helmet and mosses are very comfortable without taking excessively hot (tested in January, outside), the headband is firm and provides good support, very suitable for the compak or course where there are some head movements. Sound insulation is of excellent quality, when tested with the headset off, you hardly hear anything, there is my point of view better insulation than a "classic" headphones. Amplification of ambient sound is stirring, we distinctly heard launchers send the plates to over 30 meters, giving a confirmation "audio" the departure of the plateau, a considerable advantage in fast shooting competitions. The detonations are perfectly cut, even a little dry hand clap near the ears is cut by the microphones. Now I understand why the shooting champions are equipped PELTOR, it seems hard to beat compared to other headphones I've tried.
