I don't even know where to start, because I can't take you seriously.
Haven't had serious issue with peoples mics for years, don't even hear iPhone ear buds on playstation no more (If you heard em you would understand). Perhaps you play with meth heads that have thrashed stock Sony earbud.
Your NWAF duper raid video. if you were in my party with that audio, I would mute you. Cheap condensers like At2020, are still sensitive, as evidenced in the background noise, (tv/ipad playing, someone/something moving about) and EMF hum. Hard surface reflections, check, and obviously there is a ground loop/cheap arse power supply issue, that ugly humming sound.
Samson and 2 high end drivers, smoke much crack? Samson is low end, serviceable, workman like, but nothing special.
A PSN friend in US sent me Turtle Elite800's, 7.1 surround was magnificent, but no boom mic and more importantly closed back means they collect dust. I use plantronics rig505 (wired, open back), $55 on sale, they kick it with $150 competitors. Being open back they have wider sound stage, so directional location is good. Have had Astros, meh, the Beats of gaming, don't like hyped freqs, although a bump at 500mhz is helpful for catching footsteps earlier.
Anyway you either trolling, or trying to brag about you low end set up.
