The heat cooked the loc-tite which holds the flywheel retainer screws in place. I want to replace it with something that has terminal posts that I can count on. I really like this thing, especially now that it is warm enough that I can be out on my deck BBQing and listening to tunes wirelessly. There is a small amount of adjustment you can make with the velcro strap, but all it does is bunch up the main strap and is pretty silly as a design. For $7 and change, you get what you pay for. I thought it would be more convenient. Its very easy to use and the battery life is unbelievable, I just charged them when I got it (I took a picture, its showing the charge level), so Im using everyday for about 2-3 hours for about 7 days and still have battery. Well worth the price tag, but remember these are professional headsets so dont think you can get away with using them for gaming on a PS4, they are not designed for that use. Shoes finally showed up. I am using it with a Pixel 4XL.
