The Keychron K3 Ultra-Slim 75% Layout Mechanical Keyboard, Version 2, boasts an impressive array of features that set it apart as a top contender in the mechanical keyboard market. Let’s delve deeper into its key features and understand why it stands out among its competitors.

The Keychron K3’s ultra-slim 75% layout is a standout feature that strikes a perfect balance between functionality and portability. This compact form factor ensures that the keyboard takes up minimal space on your desk, making it ideal for users who value a clutter-free workspace. Despite its smaller size, the K3 doesn’t compromise on essential keys, ensuring that all your primary functions are easily accessible.

One of the standout features of the Keychron K3 is its Bluetooth 5.1 connectivity. This advanced wireless technology guarantees a stable and reliable connection between the keyboard and your devices. With Bluetooth 5.1, you can enjoy seamless multitasking by connecting up to three devices simultaneously. This means you can effortlessly switch between your laptop, tablet, and smartphone with just a press of a button. Whether you’re a professional juggling multiple devices or a casual user looking for convenience, the K3’s Bluetooth 5.1 connectivity ensures a hassle-free typing experience.

In addition to its wireless capabilities, the Keychron K3 also offers a wired mode. With its USB Type-C connection, you have the option to connect the keyboard directly to your device for uninterrupted performance. This wired mode is particularly beneficial for intense gaming sessions or situations where a wired connection is preferred, providing a latency-free experience. The versatility of the K3 allows you to choose between wireless freedom or a stable wired connection, depending on your specific needs.

The Keychron K3 Ultra-Slim 75% Layout Mechanical Keyboard, Version 2, combines an ultra-slim design, Bluetooth 5.1 connectivity, and the option for a wired connection, making it a versatile and practical choice for users seeking a reliable and feature-rich mechanical keyboard. Whether you’re a professional on the move, a gaming enthusiast, or simply someone who values a compact and efficient typing experience, the Keychron K3 is designed to meet your needs.


The Keychron K3 sets a high standard when it comes to its keycaps, focusing on both elegance and durability. Crafted from high-quality ABS plastic, these keycaps offer a premium feel and are built to withstand the test of time. The sleek matte finish not only adds a touch of sophistication but also helps to resist fingerprints, keeping the keyboard looking clean and pristine even during long typing sessions.

The design of the Keychron K3’s keycaps ensures a comfortable and satisfying typing experience. The sculpted keycaps provide a natural contour for your fingers, allowing for effortless key presses. The well-spaced key layout further enhances accuracy and reduces the chance of accidental keystrokes. Whether you’re a professional writer, a programmer, or a passionate gamer, the Keychron K3’s keycaps are designed to support your productivity and gaming needs.

One notable advantage of the Keychron K3 is its compatibility with both Mac and Windows layouts. Regardless of your preferred operating system, the keycaps are designed to cater to your specific needs, ensuring a seamless and user-friendly typing experience. This versatility makes the Keychron K3 an excellent choice for users who switch between Mac and Windows devices frequently or work in diverse environments.

While the Keychron K3’s keycaps offer a satisfying overall experience, it is worth noting that they are not double-shot keycaps. Double-shot keycaps are made by molding two different layers of plastic together, resulting in legends (keycap markings) that are more resistant to wear and fading over time. Some users might consider the absence of double-shot keycaps as a minor drawback, as they offer enhanced longevity and a more durable legend imprint. However, it’s important to note that the Keychron K3’s keycaps are still crafted from high-quality ABS plastic, which provides a solid balance between affordability and longevity.

Comparing the Keychron K3’s keycaps with another product, the Ducky One 2 SF Mechanical Keyboard stands out. The Ducky One 2 SF features double-shot PBT keycaps, which are known for their exceptional durability and resistance to wear and tear. The double-shot molding process ensures that the keycap legends will not fade over time, even with heavy use. While both keyboards offer high-quality keycaps, the presence of double-shot PBT keycaps on the Ducky One 2 SF gives it an edge in terms of long-term durability and legendary longevity.


The Keychron K3 incorporates low-profile Gateron Brown switches, designed to provide a superb typing experience that combines tactile feedback with smooth keystrokes. These switches strike a delicate balance between the satisfying “bump” sensation upon actuation and the smoothness required for rapid typing or gaming. Whether you’re composing lengthy documents, programming code, or engaging in intense gaming sessions, the Gateron Brown switches deliver a responsive and enjoyable feel.

One of the key advantages of low-profile switches, such as those found in the Keychron K3, is their reduced finger travel distance. With a lower actuation point compared to traditional switches, the low-profile design minimizes the time and effort required to register key presses. This reduction in finger travel distance translates to faster typing speeds and decreased finger fatigue, enabling you to maintain productivity during long work sessions or competitive gaming marathons.

It is important to note that while the Keychron K3’s low-profile Gateron Brown switches provide an exceptional typing experience, the absence of hot-swappable switches may be considered a downside for users who enjoy customization or frequently experiment with different switch options. Hot-swappable switches allow users to easily swap out switches without soldering, providing flexibility and the opportunity to tailor the keyboard’s feel to individual preferences. In this regard, some other keyboards, such as the Keychron K8 or the GMMK (Glorious Modular Mechanical Keyboard), offer hot-swappable switch functionality, which allows users to explore various switch types and easily replace them as desired.

Comparing the Keychron K3’s switches with another product, the Ducky One 2 SF Mechanical Keyboard stands out. The Ducky One 2 SF offers a variety of switch options, including Cherry MX switches renowned for their reliability and precise actuation. While the Keychron K3’s low-profile Gateron Brown switches provide a different typing experience with their low-profile design, the Ducky One 2 SF offers a broader range of switch choices, catering to users with specific preferences for the type of tactile feedback, actuation force, or audible feedback they desire.


The Keychron K3 Ultra-Slim 75% Layout Mechanical Keyboard, Version 2, excels in terms of performance, offering a remarkable typing and gaming experience. The Gateron Brown switches featured in the K3 provide a satisfying tactile feedback, ensuring a pleasant and responsive typing experience. Whether you’re writing documents, coding, or engaging in extended typing sessions, the K3’s switches deliver the right balance between actuation force and smooth keystrokes, allowing for efficient and comfortable input.

With its 84-key layout, the Keychron K3 ensures that all essential keys are easily accessible without sacrificing functionality. The compact form factor does not compromise the keyboard’s ability to cater to your needs, whether it’s navigating spreadsheets, utilizing shortcut keys, or executing complex gaming commands. The well-thought-out layout contributes to enhanced productivity and smoother workflows, making the K3 a versatile choice for both work and play.

One notable aspect of the Keychron K3’s performance is its anti-ghosting and N-key rollover features. These advanced technologies ensure accurate input recognition, even during intense gaming sessions or when multiple keys are pressed simultaneously. With anti-ghosting, you can confidently execute complex key combinations without worrying about missed keystrokes or signal conflicts. The N-key rollover functionality guarantees that each keystroke is registered, enabling precise and reliable input, particularly in fast-paced gaming scenarios where responsiveness is crucial.

The Keychron K3 also offers customizable RGB LED backlighting, adding a touch of personalization to your typing experience. With a variety of vibrant lighting effects and color options, you can create a visually appealing setup that matches your style and preferences. Whether you prefer a subtle glow or a dynamic light show, the RGB backlighting on the K3 allows you to set the mood and showcase your individuality.

Comparing the performance of the Keychron K3 with another product, the Anne Pro 2 Wireless Mechanical Keyboard stands out. While both keyboards offer wireless capabilities, compact layouts, and versatile switch options, the Keychron K3’s performance is highlighted by its anti-ghosting and N-key rollover features. 

These features ensure precise and reliable input recognition, making it an excellent choice for gaming enthusiasts or users who rely on quick and accurate typing. However, it is worth noting that the Anne Pro 2 also delivers a solid performance with its customizable RGB backlighting and a wide range of switch options.

Value for the Money:

When it comes to value for the money, the Keychron K3 Ultra-Slim 75% Layout Mechanical Keyboard, Version 2, offers an impressive package that justifies its price tag. Positioned competitively within its segment, the K3 provides a well-rounded set of features and a visually appealing design that catches the eye.

One of the key factors contributing to the K3’s value is its versatility in connectivity options. With Bluetooth 5.1, the K3 ensures a stable and reliable wireless connection for up to three devices simultaneously. This feature enables seamless multitasking and effortless device switching, which is especially useful for professionals who work with multiple devices or users who prefer a clutter-free workspace. 

Additionally, the keyboard offers a wired mode with USB Type-C connectivity, allowing for uninterrupted performance when a wired connection is preferred or when using the keyboard for gaming purposes. The combination of wireless and wired connectivity options makes the Keychron K3 highly adaptable to different usage scenarios, catering to the needs of both productivity and gaming enthusiasts.

The compact layout of the Keychron K3 is another aspect that enhances its value. By saving valuable desk space, the K3 provides a clutter-free and efficient working environment. The 75% layout strikes a balance between functionality and portability, ensuring that essential keys are readily accessible while maintaining a compact form factor. This design makes the K3 an ideal choice for users who are frequently on the move or have limited desk space but still require the performance and comfort of a mechanical keyboard.

The low-profile Gateron Brown switches further add value to the Keychron K3. These switches deliver a delightful typing experience with their tactile feedback and smooth keystrokes, reducing finger fatigue during extended typing sessions. The low-profile design also contributes to enhanced comfort by minimizing finger travel distance. This feature is particularly beneficial for users who spend long hours typing or gaming, as it allows for increased efficiency and reduced strain on the fingers.

However, it’s worth noting that the absence of dedicated multimedia keys might be considered a drawback for users who heavily rely on such functionality. Multimedia keys provide convenient shortcuts for controlling audio playback, adjusting volume, or managing media files. The lack of dedicated multimedia keys on the Keychron K3 might require users to rely on alternative key combinations or use software-based solutions to access multimedia controls.

Comparing the value for the money of the Keychron K3 with another product, the Ducky One 2 SF Mechanical Keyboard stands out as a worthy contender. The Ducky One 2 SF offers a high-quality build, a range of switch options, and double-shot PBT keycaps, which are known for their durability and longevity. 

While the Keychron K3 provides wireless and wired connectivity options, a compact layout, and low-profile switches, the Ducky One 2 SF offers premium features such as double-shot keycaps and a wider range of switch choices. Both keyboards offer excellent value, and the choice between them ultimately depends on individual preferences and priorities.
