Described are dual button push to talk devices that enable a user to simultaneously monitor multiple call nets/voice conferences and selectively respond on each call net that includes a PTT controller that connects to/controls audio streams received from a radio and a voice telephony EUD, selectively routs the audio streams from the radio and the EUD to left and right earpiece outputs simultaneously and selectively routs audio received from microphone input to the radio and the EUD. The PTT receives the radio audio streams through a radio interface and microphone input audio is selectively routed to the radio through the radio interface. The PTT may also include an EUD input, wherein the EUD audio stream is received through the EUD input and a EUD microphone output, in which the audio received from the microphone input is selectively routed to the EUD microphone output.
