There is also an actively ventilated face pad from "BoboVR" that I've found to help a lot with the eyepieces fogging up, which they otherwise will do, especially with the snap-in prescription lenses from FramesDirect. (Those need ventilation holes too, though; they'll fog up in the space between the prescription lens and the stock one. I haven't taken a pin vise to mine yet, but intend soon to, as that's the only place I still have fogging problems with the fan running.)
The Quest 2 stock strap sucks. You really need an "elite strap" or something like it. For Beat Saber or anything even vaguely like it, you also want knuckle straps for the controllers, so you don't have to worry about holding on to them or about failing to hold on to them.
The stock strap doesn't feel secure to me, even with headphones over it - I get shy about moving my head for fear I'll lose the headset. The "elite strap"'s knob-tightening mechanism holds everything much more firmly in place.
