HMX FJ400 vs. PH Studio Jacaranda
An in-depth look at the HMX FJ400 and the PH Studio Jacaranda switches—which one is the best fit for you?
Overview
When it comes to selecting the perfect mechanical keyboard switch, the choice often narrows down to personal preference, typing feel, and sound profile. The HMX FJ400 switch is revered for its balanced sound signature, striking a middle ground in the HMX Film switch lineup, making it an excellent choice for typists who seek a harmonious blend of tactile feedback and auditory experience. On the other hand, the PH Studio Jacaranda, produced by KTT, is distinguished by its light and gentle bottom-out of 43.5g, providing a fatigue-free typing experience that caters to those who type for extended periods. With a clacky and high-pitched sound profile, the Jacaranda not only delivers a satisfying auditory feedback but also features a bouncy action thanks to its extended 22mm spring, creating a uniquely engaging tactile experience. Both switches offer compelling benefits tailored to different user preferences, but the nuances in their design and sound will significantly influence your choice. However, let's dive in a bit deeper beyond generalities so you can best decide on the ideal switch for you.

Housing materials
The HMX FJ400 and the PH Studio Jacaranda present a fascinating study in contrasting housing materials that significantly influence their sound profiles and overall typing experiences. The FJ400 features a top housing made from POM (polyoxymethylene), which is known for its ability to create a unique sound that tends towards the deeper and more muted side. This characteristic allows for a pleasant auditory experience, particularly appealing to users who prefer subtler sound while typing. In contrast, the Jacaranda uses polycarbonate for its top housing, which contributes to a sharper, higher-pitched, and more resonant sound profile. The inherent stiffness of polycarbonate not only enhances clarity but also makes it ideal for RGB lighting due to its translucency, offering visual and auditory appeal that differs from the more nuanced hue of the FJ400.
On the bottom housing front, both models utilize nylon, a traditional choice for switch construction. Nylon’s softer properties contribute to a deeper and fuller sound profile regardless of the model. The material effectively absorbs sound, providing a duller and rounder auditory experience that can make typing feel satisfying and comfortable. As both switches share nylon in their bottom housings, the resonance and feel during bottoming out will be nearly identical, creating a consistent experience in this regard. This similarity emphasizes that while the top housings diverge in acoustic characteristics, the shared nylon bottom ensures a stable foundation for sound quality.
When pressing down on either switch, users will appreciate the complementary qualities of both top and bottom housings. The POM top of the FJ400 dampens higher frequencies contributing to the overall muted acoustic experience, while the polycarbonate of the Jacaranda sharpens them, creating a distinctive clarity. Despite the difference in top housing materials, the nylon bottom ensures that the overall typing experience remains comfortable and full-bodied. Therefore, while the two switches may offer markedly different sound profiles due to their top housings, the commonality in the nylon bottom contributes to consistent sound absorption and pleasing feedback across both models.
Weight
When comparing the actuation and bottom out forces of the HMX FJ400 linear switch and the PH Studio Jacaranda linear switch, notable differences emerge. The FJ400 has an actuation force of 50 grams and a bottom out force of 58 grams, categorizing it as a medium-weight switch. In contrast, the Jacaranda features a lighter actuation force of 39 grams and a bottom out force of 45 grams. This suggests that the Jacaranda is more suitable for users who prefer a lighter touch, facilitating extended typing sessions without fatigue. Meanwhile, the FJ400’s heavier actuation and bottom out forces provide a more substantial typing experience, appealing to those who enjoy a firmer keystroke. Therefore, while both switches offer unique advantages depending on user preference, the FJ400 is the heavier option, whereas the Jacaranda is the lighter choice, making it ideal for long-duration use.
Travel distance
The HMX FJ400 linear switch features a travel distance of 3.8 mm, while the PH Studio Jacaranda linear switch has a slightly shorter travel distance of 3.5 mm. This difference indicates that the FJ400 provides a more pronounced feel during key presses, potentially offering a deeper tactile experience—ideal for users who prefer a more substantial keystroke. In contrast, the Jacaranda's 3.5 mm travel distance gives it an advantage for those favoring quicker response times, as shorter distances often facilitate faster actuation, making it appealing to gamers and users who prioritize speed. Ultimately, individuals looking for a more responsive feel may opt for the Jacaranda, while those who enjoy a more heartily felt keystroke may gravitate toward the FJ400.

Typing experience
When it comes to sound, the HMX FJ400 linear switch strikes a balanced profile, likely making it versatile for a variety of typing environments. In contrast, the PH Studio Jacaranda switch produces a more distinct auditory experience, characterized as clacky and resonant. With its high-pitched, crisp feedback, each keystroke delivers a sharp, percussive response that many users find satisfying. While the FJ400 maintains a more subdued sound, the Jacaranda's pronounced acoustics ensures that it stands out in any setup, although sound will still largely depend on the keyboard board and keycaps used.
In terms of feel, the FJ400 is not elaborated upon in the provided information, but the PH Studio Jacaranda shines with its silky smoothness, making it a pleasure to type on. The Jacaranda’s extended 22mm spring contributes to a bouncy sensation that many typists appreciate. This smooth experience minimizes resistance during both pressing and releasing keys, enhancing comfort and reducing fatigue during long typing sessions.
In summary, the FJ400 offers a balanced sound suitable for diverse scenarios, while the Jacaranda excels with a clacky and crisp sound profile alongside a notably smooth and bouncy feel. While both switches promise a quality typing experience, those seeking a distinctive auditory cue may lean towards the Jacaranda, while the FJ400 would suit those who prefer a more understated sound. Ultimately, your choice might depend on whether you prioritize sound or feel in your typing experience.
Conclusion
In conclusion, when choosing between the HMX FJ400 linear switch and the PH Studio Jacaranda linear switch, it's essential to consider your typing preferences and the overall experience you desire from your mechanical keyboard. If you prefer a medium actuation force of 58 grams and appreciate a balanced sound profile that doesn't overwhelm your auditory senses, the FJ400 is a solid choice, offering a more subdued acoustic footprint that may be ideal for a professional or quieter environment. On the other hand, if you enjoy a lighter touch with a gentle bottom-out force of just 45 grams, the Jacaranda's bouncy, silky feel and clacky sound profile could greatly enhance your typing pleasure, especially if you enjoy a tactile feedback experience with each key press. Ultimately, your decision should hinge on your comfort levels and whether you favor a more refined auditory experience or a more dynamic and pronounced sound with a smoother typing sensation. Note your specific use cases—be it for gaming, casual typing, or professional work—as these factors will guide you in selecting the switch that best complements your needs.
