I've got the Razer BlackShark V2. Don't know whether it's the best but the mic sounds almost like a studio mic. Never had any issues with it.
I have the wired version currently, but I need something wireless, and the wireless version is out of my budget unfortunately. $230 CAD.
So you're asking how to encourage them to avoid you? Mostly, as you implied, you don't want to suprise them. When you're in the area, try and stay in the open, and if you can, make a bit of noise like whistling or that. They'll naturally want to stay away where possible.
