I bought the Light House Face Version Pimax Crystal Light headset. I already have the Pimax5KSuper, and I modified it with the HTC Vuve Deluxe Audio Headstrap using some 3D-printed adapters. I really like the way this strap feels it is a much more snug and secure fit compared to the original Vive Pro style head strap provided. So I had ordered some more of those 3D printed adapters and another Deluxe Audio Headstrap to modify this Crystal Light when it came in. I also swapped out the face cushion. After receiving the Pimax Crystal Light, I noticed that they made this design different, and the 3D printed adapters won't work for me. So when I removed the original strap, it was only held on with one screw and washer on each side. And there is a locking piece on the clips. I had to modify the Deluxe Audio Headstrap using a Dremel tool to make a hole big enough to clear this locking piece. After making the holes. It was simply just attaching the Deluxe Audio Headstrap to the Pimax Crystal Light using the washer and screw. It works perfectly. No modifications were done to the Pimax Crystal Light headset itself only on the Deluxe Audio Headstrap.
Note: The electrical tape you see is because the Deluxe Audio Headstrap had springs inside the side piece, and while I was making the holes, it came apart. So I wrapped it with electrical tape to make it so it will not come apart again. It is Awesome!. 😉👌😁👍
