Plug'n'Talk FM wirelss intercom by Realistic.

Each of the two speakers needs to be plugged into the same electrical circuit (but anywhere in the house) via a two pin adaptor but there are no wires to connect the two speakers. You can plug them in any room and move them whenever you wish. So you can have one upstairs permanently on and one downstairs permanently listening. Or you can put them in different rooms and buzz through to talk to the person in the other room.
