A radiotelephone set in which a case housing a miniature microwave transceiver is strapped to the wrist of a user's hand, a microphone mounted on the strap being connected to the transceiver input whereby when the hand is raised to bring the microphone adjacent the user's mouth, the user can then transmit voice messages. An earphone placed within a finger thimble is connected by a cable normally retracted within the case to the transceiver output to reproduce messages received by the transceiver. To operate the radiotelephone set, the thimble carrying the earphone is pulled away from the case to extend the cable, the thimble then being mounted on the index finger of the hand. The hand is then raised so that the thimble can be inserted by the index finger into an ear of the user who can now hear incoming voice messages. When so raised, the hand acts to place the microphone on the strap adjacent the mouth of the user who can now send out voice messages. Thus the hand of the user and a finger thereon together function to properly orient the microphone and earphone of the set with respect to the mouth and ear of the user.
