My keyboard: PFU HHKB Pro2 - 2012
I lubed my 10 years old HHKB keyboard and add some o-rings into it. It brings more quietness when I typing(compare with Apple Magic Mouse clicking sound). The typing sound is thock now.
I recorded this video by Sony ZV-E10. The sound was also recorded by Sony ZV-E10 mic.
