The Doro 8050 is a simple touch screen smartphone which is compatible with hearing aids. It offers a number of useful features, such as: voice recognition to set reminders, type messages and play music, and GPS positioning which keeps family and friends informed of your location when the Response button is pressed. This Response button is on the back of the Doro 8050 and, when pressed, alerts trusted contacts that you need assistance. They then accept the alert and talk to you directly via a hands-free call.
