I thought I would post this article to show people how to use there existing Astro's, the Series X/S doesn't have a optical cable. However, since the new consoles lack the optical port that has traditionally been part of all of Microsoft's systems, you'll need to update Astro A50 and A40 headsets, so you use them through the USB port.

How to update Astro A40 and Astro A50 to work with Xbox Series X and Series S

1: Connect your MixAmp Pro TR (often paired with Astro A40) or Astro A50 Base Station to your PC or Mac over USB. If using an Astro A50 headset and Base Station, ensure the headset is placed on the Base Station and charging.

2: Visit the Astro Gaming site and download the Astro Command Center software for PC. A Mac version is also available.

Upon successfully updating, your Astro devices will work over the Xbox Series X or Xbox Series S integrated USB port. Simply unplug your headset from your PC or Mac, and reconnect it to your Xbox console via an USB port.

I do not take credit for this I just wanted to help other people like me who didn't know what to do.
