Sarokeys BCP vs. HMX FJ400

An in-depth look at the Sarokeys BCP and the HMX FJ400 switches—which one is the best fit for you?

Overview

When it comes to mechanical keyboard switches, the Sarokeys BCP and the HMX FJ400 present two intriguing options for enthusiasts seeking a linear experience, each with its unique flavor. The BCP, also known as Black Cherry Pies, captivates users with its creamy tactile feel and a signature poppy, clacky sound profile that elevates the typing experience to a new auditory level. Its design showcases Sarokeys' commitment to innovation, eliminating the labor involved in traditional Frankenswitch assembly, while still delivering a bouncy, responsive action that many typists crave. In contrast, the HMX FJ400 offers a more subdued yet balanced sound profile, serving as a versatile choice for those who favor a smoother typing experience without the extra auditory flair. While the BCP leans towards a lively, dynamic feel, the FJ400 may appeal more to users looking for consistent performance without distraction. However, let's dive in a bit deeper beyond generalities so you can best decide on the ideal switch for your needs.

Housing materials

When comparing the housing materials of the Sarokeys BCP and the HMX FJ400, notable differences emerge, particularly in their top components. The BCP utilizes a nylon top housing, recognized for its softer texture which contributes to a deeper and fuller sound profile. This quality is a result of nylon’s ability to absorb sound effectively, producing a muted, round auditory experience when the switches are activated. In contrast, the FJ400 opts for a POM top housing, which offers a unique sound profile that is also deeper yet slightly more muted compared to nylon. While both materials play a crucial role in the acoustic performance of the switches, the POM material delivers a distinctive auditory experience that differs from the traditional characteristics associated with nylon.

Examining the bottom housings of both switches reveals a different story, as both the BCP and FJ400 feature nylon to construct their lower halves. This shared material results in similar sound profiles when the switches are actuated. The use of nylon in the bottom housing also means that the overall sound quality remains consistent across both models when pressed, with the characteristics of nylon contributing to a fuller and deeper sound. Since the bottom housing primarily affects the bottom-out sound and feel, the two switches will generate comparable auditory feedback during use, emphasizing the plushness inherent in nylon construction.

Ultimately, the combined effects of the top and bottom housings in each model create unique sound profiles that reflect their design choices. While the BCP exhibits a more uniform nylon sound, the FJ400’s POM top introduces a contrasting dimension that makes its auditory experience distinct. However, the shared nylon bottom ensures that both switches will produce a similar deeper sound when bottomed out. Therefore, while there are differences in sound character based on the top housing material, the similarities in the bottom housing serve to unify their performance, leading to comparable results in overall typing sound and feedback.

Weight

When comparing the Sarokeys BCP linear switch and the HMX FJ400 linear switch, there are slight differences in their actuation and bottom out forces that cater to different typing preferences. The BCP switch has an actuation force of 51 grams and a bottom out force of 57 grams, while the FJ400 features a slightly lighter actuation force of 50 grams and a heavier bottom out force of 58 grams. This indicates that users may experience a marginally lighter feel when triggering a keystroke with the FJ400 switch, making it slightly more accessible for longer typing sessions. In terms of bottom out force, the BCP requires slightly less pressure than the FJ400, offering a softer landing when bottoming out. Overall, the BCP is a bit lighter in both actuation and bottom out forces compared to the FJ400, which may appeal to those who value a more delicate touch and prolonged comfort, while the FJ400 might be more suitable for individuals who prefer a heavier and more substantial typing experience.

Travel distance

When comparing the travel distances of the Sarokeys BCP linear switch and the HMX FJ400 linear switch, we see a distinct difference. The BCP has a travel distance of 3.2 mm, while the FJ400 measures at 3.8 mm. This makes the BCP the shorter option, catering to those who prefer quicker response times, such as gamers who benefit from the reduced travel distance for faster actuation. Conversely, the FJ400's longer travel distance may appeal to users who appreciate a more substantial feel and deeper engagement when pressing down on keys, offering a less abrupt experience. Therefore, your choice between these two switches should depend on your preference for either a snappier action or a more pronounced depth in key presses.

Typing experience

When it comes to sound, the Sarokeys BCP linear switch delivers a unique auditory experience characterized by a clacky profile. This sound is sharp, crisp, and bright, evoking a percussive quality that many enthusiasts find satisfying. In contrast, the HMX FJ400 linear switch is noted for its balanced sound profile, though specifics regarding its sound characteristics are lacking. While the FJ400 may not reach the same level of acoustic excitement that the BCP provides, it could still offer a pleasant typing experience. It's essential to remember that the overall sound can be influenced by factors like the keyboard construction and keycap material, which could mitigate differences between the two.

In terms of feel, the BCP excels with its distinctive combination of a bouncy and creamy typing sensation. The bounciness provides a spring-like feedback that adds a lively dynamic to the keystrokes, while the creamy aspect ensures a smooth, buttery glide across the keys. This combination creates a truly enjoyable tactile experience, making each keystroke feel satisfying and effortless. Unfortunately, there is no detailed information available on the feel of the HMX FJ400 linear switch, leaving a gap in this comparative analysis. Without these details, one cannot fully ascertain how it feels in comparison to the engaging tactile response offered by the BCP.

In conclusion, while the Sarokeys BCP linear switch stands out with its clacky sound profile and bouncy, creamy feel, the HMX FJ400 linear switch remains somewhat of an enigma due to the lack of detailed sound and feel descriptions. Those drawn to the auditory and tactile excitement may lean towards the BCP for its invigorating characteristics, while the FJ400 could still serve as a suitable alternative, particularly for users who prefer a more neutral sound. Ultimately, both switches cater to different preferences, ensuring that newcomers can find options tailored to their typing style and auditory tastes.

Conclusion

To conclude, when deciding between the Sarokeys BCP linear switch and the HMX FJ400 linear switch, your choice largely depends on your typing preferences and what you value most in a typing experience. If you’re looking for a switch that provides an engaging acoustic profile and a delightful bounce, the BCP is the way to go. Its clacky sound and bouncy, creamy feel establish a unique character, making it suitable for typists who appreciate auditory feedback and a lively tactile experience. This switch can be particularly appealing if you enjoy a more playful typing session, whether you're gaming or composing. On the other hand, if you prefer a more subdued sound with a balanced performance, the HMX FJ400 might be the better option for you. With its medium bottom out force and balanced sound profile, the FJ400 is ideal for a versatile typing experience that doesn't distract your focus. Its design is tailored toward those who favor a straightforward, less noisy environment yet still desire a smooth and consistent key feel. Ultimately, both switches offer unique advantages, so your decision should align with your personal preferences and intended use case.
