This Voice Clarifying Amplifier fits snugly into the aural cavity (that’s ear hole to you!) and amplifies voice pitch while dampening down background clatter to make it easier to hear what’s what. It uses rechargeable batteries and each 12 hour charge gives 10 hours of listening pleasure. I guess if you need more time, you can just buy two units and swap them out when one runs out. Priced at $299.95.
This is the digital earpiece that amplifies and clarifies voices while minimizing distracting background noise. An advanced microchip amplifies human speech frequencies and dampens background noise 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 device eliminates the need to repeatedly purchase costly replacement batteries and operates for up to 10 hours after a 12-hour charge.
