A:AnswerYES IT DOES. Only ONE of the three handsets has an audio jack. It's the most rugged durable handset. It does not come with the audio head set. Works fine for me in my metal workshop.
A:AnswerKindly be informed that the handsets are connected together by the Base Unit and in consequence the telephone line needs to be connected to the main base so you can use the handsets as Cordless units.
