The M-Series is our dream Premium Electronic headmuff. Inspired by our own shooting experiences, and the various headmuffs we've used over the years. We set out to make the perfect over-ear protection that would meld comfort, functionality and communication into one neat little package. What we came up with is the M-Series; the all-in-one headmuff that was made for shooters. The comfortable fit, sleek design and hearing enhancement make it the last pair of headmuffs you'll ever need. 25 db of noise reduction. Two directional microphones enhance useful noise. Automatic Electronic Shutdown protects against noises over 85 db. Scrolling dials adjust to any level of desired enhancement. Smartphone compatible auxiliary ports. Black.
