Voicebooster I've had for three days. The voice booster came with a manual in fine print and diagrams too small to see without a magnifying glass. The model of the 1505 amp I purchased is not listed so I had to guess which model most closely resembled the models listed to figure out how to use it. The headset is a lightweight wire and sits comfortably on the head. The amplifier delivers what it promises --- reinforced with a volume control. Worn around the neck, the Booster moves more with the body, but poses no problem when seated. I had the amp on in my car while driving down the road, sitting in the passenger seat, going outside and in semi-quiet rooms sat. The interaction is audible and my soft voice is clear to listeners. Voicebooster is a great tool for clear communication. Outstanding quality for your money.
