Our high-powered hearing enhancer is a gem of an item. 

First of all, if you find yourself straining to hear words because you are in the back of the theater or lecture hall, this breakthrough in sound magnification technology will give you the words clearly and distinctly. Lightweight (it's not much more than an ounce) and compact, it amplifies sounds up to 50 decibels. And, if you happen to overhear an interesting business lunch conversation or eavesdrop on your daughters boyfriend, who's to know? The Cyber Ear is not much bigger than a cigarette lighter, and fits neatly (and discretely) into a shirt pocket or clips on a belt; the stereo earphones provide excellent audio quality and volume control. It's perfect for virtually all occasions: You can listen to your favorite TV show with friends and family without asking for higher volume (but it's not a medical device for the hearing impaired.) Sit in a park and listen to every creature crawling or flying around you. Hear conversations 20 feet away as if they were talking in your ear. Uses one AAA battery (included). Measures: 2 3<4" x 1 1<2" x 1<2"
