The Audio System for the Oculus Quest allows you to use high quality headphones instead of the integrated audio of the Oculus Quest 1. It is not compatible with the Quest 2.
The system plugs into the Oculus via the 3.5mm headphone jacks. The cable is spiraled in order to avoid any snagging when putting the Quest on or off. The headphones use high quality drivers from KOSS, identical to the Porta KOSS Pro headphones.
The headphone stem allows for free movement and adjustability in all directions.
If you wish to buy the Audio System without using my Headmount Pro you can use the provided clips which allows you to use the Audio System on the stock Quest headband.
