Just received the unit and stepped out the door to visit the range. The headset is quite comfortable. I have found many other brands to be uncomfortable. Someone was shooting a 50bmg and my ears were protected. I wear hearing aids under the ear muffs and the protection was still excellent. The muff does push up somewhat when using a rifle, but not enough to move away from the ear. The attenuation is perfect, hardly noticing the drop in volume.
