Review on Armorwerx Replacement Compatible Peltor Headsets by Brian Cox

(microphone arrived with no instructions or shipping papers) After plugging in the two-pin plug, I activated the Peltors and when I tried adjusting the volume all I could hear was an intermittent electronic Volume. Hissing, (both ears) high-pitched whistles, grating noises, etc. I've unplugged my Peltor, turned it off, and then turned it back on a few times. The problem remains. Your $40 product permanently damaged a $400 pair of headphones.
