I am out of warranty, but I have just recently built an AMD gaming machine. With the original cable, I couldn't use my motherboard's USB C jack. I also had some intermittent issues with WMR seeing the headset. So, I bit the bullet and ordered one. With shipping and tax it was nearly $200. What I should have done was order a completely new headset since they are on sale right now for $450. As it stands, I got the new cable and it fixed the USB C issue I had, so I no longer need the adapter. I need more time to assess the intermittent connection problem, but so far it has worked great for three days.
I also have a Quest 2 and briefly tried flying with that again. I have a new router that allows me to use it wirelessly with no discernable difference in image quality or latency compared to the link cable. I am bringing it up because every time I try the Quest 2 and switch back to the Reverb G2, I am reminded why I have tolerated the problems the G2 brings: the image quality is undeniably far superior, which really shows up in DCS World cockpits where I need to be able to clearly read gauges, displays, and control labels. Another problem I have with the Quest 2 is battery life. Using the link cable slows the discharge rate a little bit, but I still kill the battery before I am ready to stop flying. Using wireless only kills the battery faster, but does free up the USB port to use an external battery pack.
I can't wait until the PC and gpu tech gets good enough to drive something better than the G2 at 90+ fps with maxed out quality settings. But I enjoy the benefits of VR so much that it is painful to go back to a 2d flat panel monitor and TrackIR. Graphics look and run way better on the 4K 49-inch HDR TV I am using, but despite inferior graphics and frame rate, the VR experience is in all other ways so much better. So, until hardware performance advances and a better headset becomes available, the Reverb G2 is my best option for all of my VR supported flight sims, which is nearly all of them.
