Never heard a mechanical that didn't clickety click or tapity tap.
So what is the advantage then? The key presses being much noisier seems like much more of a con than the pro of better feeling key presses.
Mechanical keyboards are loud. I got a Corsair with Cherry MX Red switches. I tried for less than five minutes. It is too loud to use.
Are the Cherry MX Brown keyboards that much quieter? Maybe I will stick with rubber dome keyboards.
The keys seem to take more force to press down as well. The travel also seems longer. I am not seeing what the hype is about.
There is no difference in the noise for red and brown switches. The browns have a tactile bump while the reds do not. You can try an o-ring mod - the Logitech 710+ have those.
