HMX FJ400 vs. KTT Vanilla Ice Cream

Overview

When it comes to mechanical keyboard switches, the HMX FJ400 and the KTT Vanilla Ice Cream are two linear options that appeal to both casual typists and gamers alike, each with its unique characteristics. The FJ400 is celebrated for its balanced sound profile, making it a versatile choice for those who prefer a predictable keystroke without excessive noise. It's especially suited for users who seek a solid middle ground in typing experience and acoustic performance. In contrast, the KTT Vanilla Ice Cream switch distinguishes itself with its innovative use of POK material in both the stem and bottom housing, offering a remarkably smooth and creamy touch reminiscent of its namesake dessert. This switch produces a high-pitched and clacky sound signature, which can be a delightful experience for those who enjoy a more resonant typing feel. While both switches provide linear action, the choice ultimately hinges on personal preference for sound and tactile feedback. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials

When examining the housing materials of the HMX FJ400 and the KTT Vanilla Ice Cream, noticeable differences emerge primarily from the compositions of their top and bottom housings. The FJ400 boasts a POM top housing known for its unique capacity to produce a sound profile that leans towards deeper and more muted tones. Conversely, the Vanilla Ice Cream features a proprietary KTT blend for its top housing, which incorporates "special mixed materials" and delivers a sound signature that is high-pitched and clacky. These contrasting sound profiles indicate that while both switches aim to offer distinct auditory experiences, the FJ400 leans towards a softer resonance, while the Vanilla Ice Cream prioritizes a sharper sound signature.

The bottom housings also reflect a contrast in material choice, with the FJ400 employing a nylon housing and the Vanilla Ice Cream using a POK material. Nylon, recognized for its classic use in switch construction, contributes to a deeper, fuller sound profile by absorbing more sound due to its relatively softer nature. This results in a duller, rounder auditory sensation when typing. On the other hand, POK material enhances durability and smoothness, with exceptional resistance and a relatively high coefficient of friction compared to nylon. This difference in material properties influences the tactile feel and acoustic output, with nylon favoring warmth and fullness, while POK emphasizes clarity and resilience.

The performance of these switches can be predicted based on the materials used in both housings; despite their differences, similar auditory outcomes can be achieved when considering the effects of each material. The bottom housing in both switches has a dominant influence on the bottom-out sound and tactile response, whereas the top housing governs the sound generated when a key is released. Thus, if sound profiles can overlap, the FJ400’s depth may harmoniously blend with the Vanilla Ice Cream’s clarity, leading to a richly nuanced typing experience. In scenarios where the top and bottom materials differ, an understanding of how they interact helps in achieving desired auditory and tactile sensations tailored to user preferences.

Weight

When comparing the HMX FJ400 linear switch and the KTT Vanilla Ice Cream linear switch, a notable difference in actuation and bottom out forces can be observed. The FJ400 features a heavier actuation force of 50 grams and a bottom out force of 58 grams, placing it in the medium range. In contrast, the Vanilla Ice Cream has a lighter actuation force of 43 grams and a bottom out force of 48 grams, categorizing it as a light switch. This distinction means that users looking for a more relaxed typing experience might prefer the Vanilla Ice Cream for extended sessions, while those desiring a more substantial feel in their keystrokes might lean towards the FJ400. In summary, the FJ400 is the heavier option, making it suitable for those who appreciate a stronger push, whereas the Vanilla Ice Cream, being lighter, is ideal for long typing or gaming periods.

Travel distance

The HMX FJ400 linear switch features a travel distance of 3.8 mm, while the KTT Vanilla Ice Cream linear switch has a slightly shorter travel distance of 3.5 mm. This makes the FJ400 the longer option, providing a deeper keypress that some users may prefer for a more substantial feel. In contrast, the Vanilla Ice Cream's shorter travel distance may appeal to gamers or users who prioritize responsiveness and quicker actuation times. Thus, if you favor a more tactile and hearty experience, the FJ400 would be the better choice, whereas the Vanilla Ice Cream suits those seeking speed and efficiency in their keystrokes.

Price comparison

Typing experience

In terms of sound, the HMX FJ400 linear switch offers a balanced sound profile that sits comfortably between a full-bodied and muted acoustic experience. Its sound is non-intrusive, making it suitable for environments where noise levels need to be kept in check. On the other hand, the KTT Vanilla Ice Cream linear switch delivers a high-pitched and clacky sound signature, characterized by its marbly and resonant qualities. This creates a sharp and crisp auditory experience that is engaging for typists who appreciate a pronounced sound, reminiscent of tapping on a marble surface or hearing two billiard balls collide. This distinct sound profile, however, may not appeal to everyone, especially those who prefer deeper, more subdued acoustics.

When considering the feel of each switch, the FJ400 is positioned as an excellent middle ground within the HMX Film switch lineup, appealing to users seeking an all-around experience. Although specific descriptions of its tactile feedback are not provided, one can infer that its balanced nature suggests a competence in delivering a pleasant typing journey. In contrast, the KTT Vanilla Ice Cream switch is recognized for its remarkable buttery and creamy feel, with an emphasis on a smooth and fluid keystroke experience. This sensation is not just a result of its design and construction materials but may also be enhanced by factory-applied lubrication, leading to a silky typing experience that feels effortless and luxurious.

In conclusion, while the FJ400 is celebrated for its balanced sound profile and likely commendable feel, the KTT Vanilla Ice Cream switch differentiates itself with a high-pitched, clacky sound and a uniquely smooth typing experience. For users seeking a harmonious blend of auditory and tactile qualities, both switches offer their own advantages. If you appreciate a more pronounced sound with creamy tactile feedback, you'll likely find the Vanilla Ice Cream switch preferable, while those who prioritize a more subdued auditory profile may prefer the FJ400. Ultimately, your choice will depend on your individual preferences regarding sound and feel.

Conclusion

To conclude, when deciding between the HMX FJ400 and the KTT Vanilla Ice Cream linear switches, your choice should hinge on your personal preferences and typing needs. If you prefer a medium bottom-out force and a balanced sound profile, the FJ400 may suit you well, especially if you like a more subdued auditory experience that still maintains a satisfying tactile sensation. On the other hand, if you gravitate towards a lighter bottom-out force with a fun and vibrant feel, the Vanilla Ice Cream is an excellent option. Its buttery and creamy keystrokes deliver a smooth typing experience, while the high-pitched, resonant sound makes it an engaging choice for those who appreciate auditory feedback. In essence, if you are looking for versatility and a balanced feel, the FJ400 is your switch. However, if you want an expressive and delightful typing experience, the Vanilla Ice Cream will likely bring you joy. Consider what aspects matter most to you—force, sound, or feel—to make the best decision for your mechanical keyboard setup.
