Switch Gateron Brown is quite quiet when pressed. The Keychron K2 is also available in a fairly clicky Gateron Blue and Red Switch option.

Keychron also provides a special switch made by them for this keyboard, namely the Low Profile Optic keychron.

Keychron K2 vs Keychron K3 Typing Quality

I think the quality of typing on the k3 keychron is better in terms of ergonomics because the k3 keychron has a low profile so that the movement of fingers from one key to another feels very easy. Even though both keyboards have a 75% layout, I find it easier to adapt to the k3 keychron than the k2 keychron due to their slightly higher profile.

For the switches used, it all depends on your taste. If you want a quiet switch, choose a brown gateron, if you want a clicky switch, choose a blue or red gateron.

Then to add a better typing experience, we recommend you to replace the ABS keycaps with PBT Keycaps which you can buy on the keychron website.
