Amazing sounding switches on the Glorious Gmmk 2 65. They sound so creamy and thocky with a very solid actuation force and lots of stability. They are some of the nicest-sounding switches I have ever used. This has helped me dramatically with touch typing because of the solid feedback and consistent linear travel. This full sound signature helps eliminate mistakes when typing, and the marbly sound signature is addictive.
Its the first ball-bearing switches I've tried, and I'm happy to find that its the smoothest switches I've had on my keyboard; it even makes my lubed gateron milky yellows feel rattly and hollow in comparison. These also sound surprisingly deep and almost marbly for how light they are, and have been very nice and non-fatiguing to type on as someone who types at over 150wpm :)
