Available only from Hammacher Schlemmer, this is the digital earpiece that amplifies and clarifies voices. An advanced microchip amplifies human speech frequencies above background noise in this voice amplifier so that spoken words are clearly audible. Unlike lesser analog models that merely make all sounds louder, this superior digital earpiece amplifies voice pitch so words are easier to discern. The rechargeable portable voice amplifier device eliminates the need to repeatedly purchase replacement batteries and operates for up to 10 hours after a 12-hour charge. The ear amplifier with a voice enhancer has eight adjustable volume levels and recharges in the carry case that’s powered by the AC adapter or two AAA batteries (included). Includes one amplifier (additional amplifier available below) and four different sized silicone caps to accommodate most ear sizes. (1/10 oz.)
