Work is tricky because everyone gets upset because of the noise.
I actually take a cheap RK68 Plus and added Outemu Silent Peach switches, some of those keycap o rings, and some custom key caps. Its not by fav. typing experience but now its more quiet then the membrane keyboards everyone else uses. And everyone eyes its jealously.
I work at home, in a small office with my partner. For my first mechanical, and mindful of their sanity, I fitted Outemu Silent Forest switches to a cheap 65% Amazon kb. It's remarkably quiet though the cheap kb generates a lot of noise, relatively.
I recently got a Keychron Q2 with Gateron reds. I'd planned to change to their silent blacks but the sound is such a lovely gentle click I haven't bothered. I fitted a few switches to compare and my partner specifically said they were enjoying the gentle click, and not to change it.
I do still covet the whisper-quiet boards, though...
I should have clarified that I use it for remote work. I have a Vortex POK3R 60% keyboard for in-office work with Cherry MX reds. I might have to check out the Silent Peach ones - those are tempting.
