Abstract: Electronic devices and accessories such as headsets for electronic devices are provided. A microphone may be included in an accessory to capture sound for an associated electronic device. Buttons and other user interfaces may be included in the accessories. An accessory may have an audio plug that connects to a mating audio jack in an electronic device, thereby establishing a wired communications link between the accessory and the electronic device. The electronic device may include power supply circuitry for applying bias voltages to the accessory. The bias voltages may bias a microphone and may adjust settings in the accessory such as settings related to operating modes. User input information may be conveyed between the accessory and the electronic device using ultrasonic tone transmission. The electronic device may also gather input from the accessory using a voltage detector coupled to lines in the communications path.

Abstract: Electronic devices may be provided with audio circuits and circuitry configured to support communications and test mode operations. During normal operation, a standards-compliant connector such as an audio connector may be inserted into a connector port in an electronic device. The audio connector may be associated with a headset or other accessory and may be used to carry audio signals. During test mode operations, a nonstandard test connector may be inserted into the connector port. The electronic device may detect the presence of the nonstandard connector and may direct the electronic device to operate in a testing mode.
