Minneapolis salt is brutal, but Phoenix dust storms can sand your paint too.

I used to roll my eyes at people who said no mechanical switch is truly mic silent, figured they just had bad mics or bad technique. Then I got a "quiet" board myself and ate my words real fast, because the mic does not care about your marketing box, it cares about the sound your fingers make when they bottom out. The trick nobody tells you is that the clack is only half the switch, the other half is you slamming keys all the way down, so even a silent switch gets loud if you type heavy. What actually helped me was o rings plus a desk mat plus not hammering the keys, and even then my team could still hear it a little. If you need truly clean audio on calls, the office mush keyboard is honestly the safe play, or you mute when you type. Maybe try lubed silent linears with a foam mod if you want to stay mechanical, but do not expect the mic to hear nothing.
