The HP Reverb G2 has integrated speakers. Thus, headphones are not needed. If you still want to use headphones instead of the integrated speakers, the integrated speakers can be removed by unscrewing a small phillips head screw. This screw is located on the inside of the headset behind the integrated speakers. The HP Reverb G2 itself does not have an audio jack. However, headphones or earphones can be connected to the PC which then syncs the audio automatically with the Windows Mixed Reality portal.
