A sound rack device 6 is in Wi-Fi communication with server 4 and configured to send time codes signals thereto. A sound mixer 7 is in cable communication with the sound rack device 6 and receives audio file data corresponding to virtual reality image content therefrom simultaneously with the server 4. The server 4 is cable connected to the wireless access point 5 and configured to simultaneously message each headset 2. At least one speaker element is provided for each channel of audio being connected to the mixer 7 such that upon receipt of the audio file, the mixer 7 is configured to relay each channel audio signal to respective speakers 8 in synchronisation with the VR headset images.
