If you’re considering purchasing a virtual reality headset, you may be wondering if the Vive Cosmos is compatible with the Valve Index. In short, the two devices are not directly compatible with one another. However, it is possible to use the Vive Cosmos and Valve Index together with some additional hardware and software.

What is the Vive Cosmos?

The Vive Cosmos is a virtual reality headset developed by HTC. It features six cameras that enable inside-out tracking, allowing for room-scale VR experiences without the need for external trackers. The headset also has a high-resolution display, built-in headphones, and can be used with wireless adapters for an untethered experience.

What is the Valve Index?

The Valve Index is another popular virtual reality headset that was developed by Valve Corporation. It offers high-quality visuals and sound, as well as precise finger-tracking controllers that provide a more immersive experience than traditional handheld controllers.

Compatibility Issues

While both headsets are impressive in their own right, they were not designed to work together out of the box. The Vive Cosmos uses its own proprietary tracking system while the Valve Index relies on SteamVR tracking technology. As a result, attempting to use these two devices together will not work without some additional hardware and software.

Add-Ons for Compatibility

One way to use both headsets together is by purchasing additional hardware such as base stations that can be used for SteamVR tracking. These base stations will need to be mounted in your play area and synced with your Valve Index controllers. Once this setup is complete, you can then launch SteamVR and use your Vive Cosmos headset alongside your Valve Index controllers.

Software Compatibility

In addition to hardware add-ons, you’ll also need to ensure that your software setup is compatible with both devices. This means making sure that you have both the HTC Vive and SteamVR software installed on your computer. You’ll also want to check that any games or applications you want to use are compatible with both headsets.


While the Vive Cosmos and Valve Index are not directly compatible with one another, it is possible to use them together with some additional hardware and software. If you’re interested in using both headsets together, be prepared to invest in additional equipment and spend some time configuring your setup. With the right setup, you can enjoy the best of both worlds and experience the immersive VR experiences that these two devices offer.
