The technology relates to establishing wireless communication links, or connections, between a first audio accessory device, a second audio accessory device, and a client computing device. After receiving signals from the client computing device to initiate audio output, the first audio accessory device and the second audio accessory device may both perform a series of steps in parallel to establish connections with the client computing device and with each other. The series of steps may include relaying one or more acknowledgement (ACK) signals between the audio accessory devices in order to confirm proper receipt of the signals from the client computing device at both audio accessory devices. Alternatively, the series of steps may include transmitting a jamming signal from one of the audio accessory devices in order to prevent an ACK signal from the other audio accessory device from reaching the client computing device and initiating audio output.
