The Long Range Acoustic Device (or Sonic Blaster, for us simple people) is among the Navy's proudest feats of warfare engineering and a favored tool of law enforcement agencies. The non-lethal amp pumps out an ultra-powerful beam of sound that deters baddies from coming within 82 feet of its position. Unless, of course, those baddies decide to act fresh and bring one of these sound insulating, double-glazed head shields, which will let the wearer stand right in front of a Sonic Blaster without losing his hearing for all eternity. Created by the BBC's Bang Goes the Theory show, the head shield is a perfect complement to your favorite hoodie and casual pair of jeans for a stylish riot out on the town.
