How do Bluetooth and hearing aids work?

Bluetooth technology automatically connects 2 devices to each other wirelessly. Hearing aids that have Bluetooth technology can connect to cellphones, TV, automobile interfaces, landline phones, iPads, and computers. When hearing aids are connected to the cell phone, the phone can be used as a volume control and program changer. In addition, patients can stream music, movies, and phone calls directly to their hearing aids up to 50 feet away.
