"The Audio-EXTM personal sound enhancer is designed for anyone experiencing hearing difficulty when watching TV and other common day to day situations. It offers improved hearing for those who don't need an expensive hearing aid but occasionally need help listening in noisy, challenging situations. The unit's digital amplifier employs technology that allows you to hear more clearly while having a conversation in a noisy restaurant, listening to a public speaker in a big auditorium, attending worship services or simply watching DVDs at a comfortable volume level.
The unit's innovative one-sided headset fits comfortably and discreetly over the ear it looks like you're wearing a cell phone. Three equalizer presets allow you to customize amplification, including an option to boost only higher-frequency sounds. Automatic Gain Control (AGC) reduces over-loud voice feedback from any source. Comes with audio earbud and headset. Use it freestanding, with the included belt clip or detachable neck cord. Measures 3 1/2" x 2 1/2" x 3/4" and weighs 6 1/4 oz. Runs on 2 AAA batteries (purchase separately)."
