Abstract
A set of headphones includes a connector with a first connection contact and a second connection contact as well as a loudspeaker, which is connected to the first connection contact in order to supply a loudspeaker signal. The set of headphones also includes a first and a second digital microphone, each of which is set up to generate a digital microphone signal, in particular with a binary bit stream. A multiplexer, which is coupled, at an output, to the second connection contact, is set up to generate a coded multiplex signal at the output on the basis of the microphone signals.
