One point I would like to mention. The black switch is not really noisy, but the clacking, which arises when the keyboard buttons can be pushed through to the stop (although is not necessary, since they already react midway), is already quite loud. Since the black Cherry's with 60 grams but require the highest pressure, you hit pretty hard on the bottom. This is both for me and my wife so that not nearly as strong in the key skin like me. For this reason I have my Ryo with rubber rings with a hardness of 40 ° Shore (quite soft; the larger the value, the harder) tuned. The impact noise has been strongly reduced and the key travel is slightly smaller. I can recommend it to anyone who wants to make his jewel a little quieter. On a quiet rubber mat it is technically sound, of course not approach.
But yes you can buy also no V8 and want to have the sound of an electric motor. ;-) The clatter of caps, especially the large space bar is also maintained with rubber rings.
