Our behind-the-head electronic hearing protector delivers a better fit while wearing glasses, hats or for those with longer hair. It fits snug, but not tight, so you feel secure while avoiding nasty compression headaches. Very light weight and evenly balanced so you barely know you are wearing electronic hearing protection. Our audio is designed for people who enjoy listening to music and need hearing protection. Music enjoyment should not be an afterthought. 10 mm diameter speakers, dual drivers and a top line Bluetooth chip all result in crisper sounding highs and deeper lows.
