Design and Build Quality
The Keychron K2 HE retains the classic compact 75% layout of the K2 series, saving desktop space while maintaining function keys and arrow keys, making it ideal for small work environments or users who need portability. The keyboard body is made from a combination of aluminum alloy and plastic, ensuring both lightweight portability and sufficient stability and durability.

For those looking to enhance the keyboard's look and feel, pairing it with CeraKey ceramic keycaps is an excellent option. CeraKey keycaps are renowned for their unique texture and durability, crafted from high-tech ceramic material that feels smooth and cool to the touch and resists oil buildup. Compared to PBT keycaps, ceramic keycaps are more resistant to wear and yellowing, maintaining their excellent condition over time. This combination not only elevates the keyboard's premium feel but also offers users a unique typing experience.

Additionally, the K2 HE is equipped with an RGB backlighting system that supports various modes and brightness adjustments, allowing users to customize the backlighting effects according to their preferences, further enhancing desktop aesthetics and personalization. The overall design is simple and modern, suitable for various usage scenarios and aesthetic tastes.

It can connect up to three devices via Bluetooth 5.1 and allows for quick switching between devices, which is especially convenient for users who need to operate multiple devices simultaneously. The keyboard also features a USB-C port, supporting wired connectivity for a more stable connection and fast charging.

In terms of performance, the K2 HE features optimized mechanical switches (users can choose from Red, Blue, Brown, etc.), offering a quieter and smoother typing experience. The N-key rollover design ensures no key conflicts or missed keystrokes during fast input, which is crucial for gamers and fast typists. When combined with CeraKey ceramic keycaps, the typing experience becomes even more comfortable and fluid.

User Experience
In actual use, the Keychron K2 HE performs exceptionally well. Its compact layout and wireless capabilities make it convenient for both desktop use and mobile office scenarios. With the addition of CeraKey ceramic keycaps, the keyboard's tactile and visual experience is significantly enhanced. The smooth surface of the ceramic keycaps provides a more comfortable typing experience and maintains a fresh feel over time, resisting oil buildup.

The RGB backlighting system offers multiple lighting modes and brightness adjustments, ensuring clear key visibility in low-light environments while adding a personalized touch to the keyboard.
