The blind are lonely. They cannot see or feel the innumerable things.To blind, the greatest aspiration is to own their living by a skill they acquired through learning. Knowledge changes fate, but the high cost of learning prevents many families from moving forward for studies. This design helps them out pretty well. Through its own scanning function, the Bluetooth headset receives the right signal, then directly transmits it to the blind people's ears. Such as library, the Bluetooth headset supporting sound output protects both the body and the mind of blind people.
