Gateron CJ vs. HMX FJ400
An in-depth look at the Gateron CJ and the HMX FJ400 switches—which one is the best fit for you?
Overview
When considering which mechanical keyboard switch to choose, the Gateron CJ and the HMX FJ400 both offer unique experiences despite being linear switches. The Gateron CJ stands out with its signature higher-pitched clacks and impressively smooth actuation, creating a typing experience that many enthusiasts find delightful. This switch is renowned for its chirpy and thocky sound profile, making it an appealing option for those who enjoy auditory feedback without the tactile bump associated with other switch types. In contrast, the HMX FJ400 occupies a more balanced position within its lineup, providing a sound profile that aligns well with users seeking a neutral yet satisfying typing experience. While the FJ400 lacks the distinct sound characteristics of the CJ, its smoothness and overall versatility can cater to a wide range of typing preferences. Ultimately, both switches have their merits depending on what type of feedback and sound you prioritize while typing. However, let's dive in a bit deeper beyond generalities so you can best decide on the switch that suits your needs.

Housing materials
When comparing the housing materials of the Gateron CJ switches and the HMX FJ400 switches, notable differences in sound profiles emerge from their respective components. The Gateron CJ features a proprietary INK blend top housing, which is designed to produce a higher-pitched and clacky sound. This sound is distinguished by its sharpness, making it an appealing option for users who prefer a more pronounced auditory feedback during typing. In contrast, the FJ400 employs a POM top housing that generates a deeper and more muted sound. The difference in material characteristics contributes to the overall sound profile when the key is released, with the CJ's top housing lending itself to a brighter noise while the FJ400's top housing offers a more subdued auditory experience.
Digging deeper into the bottom housings reveals another key contrast between these two switches. The Gateron CJ bottom housing, constructed from POM, shares a similar sound quality with its top housing as it contributes to a distinctly deep and muted sound. This allows for a consistent auditory experience throughout the keystroke, making it less jarring for users who favor a particular sound profile. On the other hand, the FJ400’s nylon bottom housing provides a deeper and fuller sound due to nylon’s relatively softer nature, which absorbs more sound waves compared to harder plastics. This characteristic ensures that the bottom-out sound feels rounder and softer, offering a contrasting tactile sensation to the Gateron CJ’s qualities.
The differences in material composition between the Gateron CJ and HMX FJ400 switches ultimately create a dichotomy in tactile feedback and auditory profiling. While both switches feature unique attributes that cater to diverse user preferences, their variances also imply that an ideal typing experience can be achieved through intentional mixing of key components. A user who appreciates a bright sound can find a semblance of it with the Gateron CJ's INK blend top housing while enjoying the deeper resonance of the nylon bottom housing in the FJ400. Hence, those seeking a balanced auditory experience can explore these switches through strategic combination, leveraging the unique qualities of each housing material to achieve desired outcomes in sound and performance.
Weight
When comparing the Gateron CJ linear switch to the HMX FJ400 linear switch, both switches exhibit the same actuation force of 50 grams, indicating that users will require the same amount of force to register a keystroke with either switch. This similarity ensures that typists and gamers looking for a comfortable typing experience will find comparable performance in terms of actuation. However, the bottom out force differs slightly, with the CJ switch featuring a bottom out force of 60 grams, while the FJ400 has a slightly lighter bottom out force of 58 grams. Consequently, the Gateron CJ has a heavier overall feel due to its higher bottom out force, which may appeal to those who prefer a more substantial typing experience. In contrast, the HMX FJ400's lighter bottom out force could be more suitable for users seeking a less strenuous typing experience, especially during extended use.
Travel distance
When comparing the travel distances of the Gateron CJ linear switch and the HMX FJ400 linear switch, we find a notable distinction. The Gateron CJ features a travel distance of 4 mm, while the HMX FJ400 has a slightly shorter travel distance of 3.8 mm. This means that the Gateron CJ switch provides a deeper keypress, which some users may prefer for its more substantial feel, while the HMX FJ400's shorter travel distance may appeal to gamers seeking quicker response times. Ultimately, those who favor a more pronounced keystroke may gravitate towards the Gateron CJ, whereas those who enjoy a snappier feel might opt for the HMX FJ400, making each switch suitable for different preferences and use cases.

Typing experience
When examining the sound profiles of the Gateron CJ and the HMX FJ400 linear switches, a clear distinction arises. The CJ is characterized by its chirpy quality, which adds a unique brightness to the typing experience, making it stand out with higher-pitched clacks. Additionally, it presents a noteworthy contrast in sound with options described as low-pitched or thocky, although the introduction of a chirpy element differentiates it from other switches. On the other hand, the FJ400 has a balanced sound profile but lacks specific descriptors, which suggests its sound may be less distinctive than the CJ. The inherent acoustic qualities could change based on the keyboard and keycap combinations used, but the CJ's engaging and pronounced sound makes it a popular choice for those looking for auditory enjoyment while typing.
When considering the feel of these switches, the Gateron CJ offers a mild experience that ensures a gentle and approachable typing sensation. This smooth and pleasant response can accommodate a wide range of typists, whether they are beginners or seasoned veterans. There's no specific feel description provided for the FJ400, which leaves its tactile feedback open to speculation. However, if the FJ400 aligns with the general reputation of HMX switches, it could offer its unique smoothness and consistency. The CJ’s mild nature makes it likely to be more universally appealing, while the FJ400's tactile experience remains unknown.
In summary, the Gateron CJ linear switch presents a vibrant sound profile with its chirpy quality and thocky options, coupled with a mild feel that makes it suitable for a diverse audience. In contrast, the HMX FJ400 linear switch holds a balanced sound profile but lacks detailed descriptors, leaving its auditory identity somewhat ambiguous. While both switches will likely provide a smooth typing experience, the CJ’s engaging and enjoyable sound, combined with its approachable feel, renders it a compelling choice for anyone new to the mechanical keyboard scene. If you prioritize sound variety and a gentle touch, the CJ would be a solid choice, but those looking for a more neutral sound may find value in the FJ400 once its characteristics become clearer.
Conclusion
In conclusion, choosing between the Gateron CJ linear switch and the HMX FJ400 linear switch ultimately depends on your personal preferences and typing habits. If you’re someone who enjoys a unique and enjoyable typing experience, the Gateron CJ might be more suited to you, especially if you appreciate the chirpy sound and the smooth push feel that sets these switches apart. The CJ's bottom-out force of 60 grams offers a satisfying resistance that adds to the overall typing enjoyment, making it a great choice for both casual and enthusiastic typists. On the other hand, if you prefer a more balanced sound profile and a switch that caters well to both personal and professional environments, the HMX FJ400 may be the right pick. With a slightly lower bottom-out force of 58 grams and a neutral feel, the FJ400 excels in versatility and can suit a range of typing styles without overwhelming your auditory senses. Ultimately, it comes down to whether you prioritize a distinctive acoustic signature and tactile feel with the CJ or seek the reliable, middle-ground experience of the FJ400.
