The AddVox 7 (click picture on the left for enlarged image) voice amplification system is a great product for tour guides, teachers, aerobics instructors, athletic coaches, trade show personnel, Parkinson's and Laryngectomy patients. It is the perfect solution for those with temporary or permanent voice impairments as well as an excellent preventative mechanism to avoid vocal strain. This unit is lighter, more powerful, and longer lasting per charge, with better output clarity than many competitors.
In a crowded room or out in an open area, the ADDvox 7 watt insures that your voice will be heard by your audience. For maximum performance, its powerful 7 watt amplifier uses high capacity Nickel Metal-Hydride (NiMh) rechargeable batteries (included), that will provide up to 14 hours of continuous service following an overnight charge.
