You mentioned that the keys are too noisy for mechanical keyboards, but have you tried Cherry Silent Red switches? Here's a video that explains the Cherry MX mechanical switches: https://www.youtube.com/watch?v=zlSPH3HvxhQ

Yes, unfortunately. My 130USD cherry keyboard ended as an expensive toy for my toddler (he was using it without being connected). :(

The issue is not only the switch but the resonance with the keyboard (even with plastic rings).

(Gaming with it was superb, but I needed one for programming. Different use case.)
