I'm not one to bash a product but I feel compelled to at least provide my personal experience with the HP Reverb (2nd edition).
First and foremost, I love the resolution and I've been happy with the overall experience.
Unfortunately the weight of the cable on the Reverb, overtime and use, seems to pull on and weaken the connection within the headset. I can actually feel the tug of the cable on my head and neck. There is a clamp that holds the main video cable and headphone cable but I'm not sure it's snug enough to keep tension off the connection inside the headset itself.
As a result, the connect weakens over time and use causing the video to blacks out intermittently and introduces video noise (green speckles) flicker within the image. If I move and hold the cable in the right position, the speckles/flickers stop then return when I release the cable.
HP has been good about replacing the units, but this is frustrating.
At any rate, thought I would share this. If you are thinking to purchase, would recommend to go the HP's site and review other customer feedback on issues with the cable.
Edit... the last unit was replaced in Feb 2020
