I have discovered the reason my A462 won’t work with the headphones: the socket is lacking the circular metal housing for the jack - I just see two copper (?) connectors pointing into the hole from opposite sides and from different heights.
I assume repairing this would not be economical considering the age of the phone. Would the FM radio play through Bluetooth ‘phones? I am guessing not, as the ‘phone cord must be the antenna for the radio. Poop!
