Stealth 400 do not recommend. Plastic ear pieces broke less than a year of using them. The area was a high stress point when you went to put them around your ears. Repleacement piece is $75, and new ones cost $99. I hardly used them. Mai ly during raids and the few times a month i ran with my buddy. Fix: a broken popsicle as a splint and tons of tape til i can buy a different set work great.
