Experience Walker￢ﾀﾙs Game Earￂﾮ hearing-enhancement technology at an irresistible price. Its compact, behind-the-ear configuration makes it practically unnoticeable, but the sound amplification sure will be. Both volume and high-frequency amplification are adjustable, and there￢ﾀﾙs an on/off switch, too. A db-limiting mild-compression circuit cuts off muzzleblast and other sudden, loud noises. Fits either ear. Runs on a single LR-44 battery (three included). Includes one each small, medium and large ear tips and two maintenance tools.
