The first thing I did was add a soft strap in the middle in order to distribute the weight better. I used an Apache DAS Studioform strap:
Then I added a counterweight on the back which was simply a battery bank held by some rubber bands.
I don’t know what it is, but as soon as I made these changes, I felt much more immersed in VR. Probably because when I moved my head around, my headset stayed perfectly in place and in the sweet spot and moved in sync with my head.
I also noticed the eye strain that I used to notice often disappeared. Maybe it’s because the lenses were raised a bit higher with the strap than without one? And the clarity improved as well.
So I think if people try the Pimax 8K X and are having trouble finding the sweet spot, they should try adding at least a strap on top to keep the headset perfectly balanced.
