Keychron K2 vs Keychron K3 Keycaps And Switch

Keychron K2 is equipped with keycaps made of ABS which is paired with the Gateron Brown Switch. The Gateron Brown switch on the keychron k2 feels soft and quite responsive when pressed. Gateron Brown Switch is quite quiet when pressed. The Keychron K2 is also available in a fairly clicky Gateron Blue and Red Switch option. It all depends on your taste, which switch is suitable for your needs. We also recommend that you replace the ABS keycaps with more solid PBT Keycaps which you can purchase on the Keychron website.

Keychron K3 Keycaps And Switch

Keychron K3 is embedded with ABS plastic keycaps which feel slippery when used, we recommend that you upgrade these keycaps with PBT keycaps which are more textured and solid. Keychron K3 is equipped with a Low Profile Brown Gateron Switch which is quiet when pressed but this switch is quite responsive. There are other options for switches that you can use on this keyboard, such as the low profile blue gateron switch, or low profile linear red which has a more clicky sound. 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 green 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.

Keychron K2 vs Keychron K3 Software

Both the Keychron K2 and K3 don’t have any supporting software to set and reprogram the buttons and RGB Baclight. But Keychron recommends third-party software that can be used, namely Karabiner for macOS and SharpKeys for Windows.

Both keychron k2 and k3 are compatible with Windows, Linux, Android, iOS and MacOs operating systems. But there are some important notes. When you switch modes, make sure to use the switch to match the keyboard to the operating system you are using. The F3 and F4 keys cannot be used on devices with the iOS operating system on iPhone and iPad.

The two keyboards have slightly different prices, the keychron k2 is priced at $95 and the keychron k3 is priced at $90. With the same 75% layout, but the keychron k2 is a little more expensive maybe because of the body material used and the taller and thicker physique.


Keychron k2 and keychron k3 are two keyboards that have the same build quality as well. Keychron k2 has a build quality that is more solid and sturdy than the keychron k3.

But if you want a low-profile keyboard and better ergonomics, then the Keychron k3 is a better choice. In addition to being slightly cheaper, the keychron K3 is also more compact and easier to carry anywhere.

But if you want a keyboard with aluminum build quality that is solid and sturdy, coupled with a good typing experience, the Keychron K2 is the right choice, although the Keychron K2’s profile is higher, this keyboard is comfortable and ergonomic enough to be used for a long time.
