The Keychron K3, on the other hand, is a compact 75% keyboard that features both function and arrow keys. It’s notably lighter than the Keychron K2 (Version 2) and is designed to be highly portable. If you’re looking for a similar option but without function keys and equipped with high-profile keycaps, you might want to explore the Keychron K14.

These dimensions and size differences make both keyboards unique in their own right, catering to varying preferences and needs. Whether you favor a compact layout with function keys or the convenience of low-profile switches, these Keychron keyboards offer a range of choices to suit your typing and gaming requirements.

Build Quality: A Closer Look

When it comes to build quality, both the Keychron K1 and Keychron K3 shine in their own right. The majority of their construction is composed of sturdy aluminum, which imparts a notable sense of durability and rigidity. However, it’s worth mentioning that there is some plastic utilized on the sides.

In terms of structural integrity, these keyboards exhibit minimal flex, ensuring a robust foundation for your typing and gaming experiences. Although it’s worth noting that when applying significant pressure to individual keys, some slight flex may be perceivable, but this is unlikely to pose any issues during standard usage.

One aspect to consider is the keycaps. Both the Keychron K1 and K3 incorporate flat keycaps crafted from ABS plastic. While these keycaps contribute to the sleek aesthetic of the keyboards, they may feel somewhat slippery to the touch. It’s essential to be aware of this characteristic, as it can influence your typing experience.

An important clarification to make is that, previously, there was mention of the ability to purchase extra PBT keycaps on Keychron’s website. However, it’s crucial to note that these extra keycaps are, in fact, premium ABS, not PBT. This information has been updated for accuracy.

Additionally, the Keychron K3’s build quality deserves special mention. Its frame predominantly consists of aluminum, with some plastic components underneath. When typing, you might notice a slight wobbling of the keys, but it’s generally not conspicuous enough to hinder your typing experience. The ABS keycaps on the K3 may be susceptible to developing a shine from the natural oils on your fingertips over time, so keep this in mind for long-term use.

To enhance stability during usage, both keyboards feature four rubber feet underneath, effectively preventing them from sliding around on your desk. Additionally, you can rest assured that there are no loose parts within these keyboards, and the larger keys remain stable without rattling.

In summary, the Keychron K1 and Keychron K3 exhibit commendable build quality with their robust aluminum frames and ABS keycaps. These keyboards are designed to endure daily use and provide a solid foundation for your typing and gaming needs.


When it comes to ergonomics, both the Keychron K1 and Keychron K3 offer a comfortable typing experience, but there are some differences to consider.

Typing Quality

Typing Quality

Keychron K1:

Typing on the Keychron K1 is a decent experience. It features Gateron Low Profile Red switches that provide a smooth, linear feedback. However, the ABS keycaps can be a bit slippery, leading to more frequent typos. Furthermore, the absence of incline settings and the keyboard’s taller-than-usual profile design may lead to minor fatigue during extended typing sessions.

If you’re not a fan of Red switches, you do have the option to get this keyboard with the loud and clicky Gateron Low Profile Blue switches.

Typing on the Keychron K3 can be a pleasant experience, thanks to the Gateron Low Profile Brown switches on our unit. These switches offer tactile feedback, enhancing the overall typing quality. However, your typing experience might vary depending on the type of switches you choose.

One thing to note is that the keys on the Keychron K3 exhibit a slight wobble, although this isn’t very noticeable in regular use. The keyboard’s layout might feel a bit cramped, which could result in more typos if you’re not accustomed to it. Additionally, the right Shift key is smaller than the left Shift key, potentially causing accidental hits on the arrow keys.

Moreover, the ABS keycaps on this keyboard can feel somewhat slippery. Overall, typing on the Keychron K3 should not become tiring during extended use, and it represents an improvement over the Keychron K1.

However, if you’re not a fan of low-profile keys and prefer a compact keyboard with standard keys, you may want to consider the ROYAL KLUDGE RK61.
