HMX EVA vs. TTC Neptune
An in-depth look at the HMX EVA and the TTC Neptune switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, enthusiasts often weigh their choices based on tactile feel and sound signature, among other factors. The HMX EVA switch stands out with its vibrant design inspired by the iconic Evangelion Unit-01, providing a resonant sound and a silky smooth typing experience. This switch is perfect for those who appreciate a visually striking keyboard paired with a satisfying acoustic feedback. On the other hand, the TTC Neptune offers a unique typing experience characterized by an innovative internal structure that promotes a smooth, almost frictionless glide. Its lightweight build and springy resistance deliver a typing feel likened to chewy mochi or tapioca pearls, making it an ideal choice for users who prioritize swift and effortless keystrokes. While both switches offer distinct advantages for different preferences, the choice ultimately depends on your typing style and aesthetic values. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The HMX EVA and the TTC Neptune each utilize distinct materials for their switch housings, leading to notable differences in the sound profiles they produce. The EVA features nylon in both its top and bottom housings, known for its softer properties that contribute to a deeper and fuller sound. This material is designed to absorb sound effectively, making it ideal for users seeking a muffled yet rich auditory experience when typing. The overall result creates a rounder sound profile, which is conducive for a satisfying typing experience, especially in quieter environments. Conversely, the Neptune employs POM (for the top housing) and polycarbonate (for the bottom housing), giving it a unique sonic character that is both deeper and more muted than traditional nylon options.
While the EVA's nylon top and bottom housings produce a fuller sound quality consistently across the switch, the TTC Neptune's POM and polycarbonate combination yields a more varied auditory experience. POM’s softer characteristics in the top housing slightly resemble nylon's performance, but with a distinctive richness that enhances user engagement. On the other hand, the polycarbonate bottom housing introduces higher-pitched elements that could create a crisper sound. This contrast means that while both switches can deliver a satisfying sound when pressed or released, the EVA maintains uniformity with its nylon components, whereas the Neptune’s acoustic profile is influenced differently by the materials used in both the top and bottom housings.
Despite their differences, some qualities may lead to similar results in sound perception for users. The EVA, with its fully nylon composition, ensures a consistent experience in terms of sound from both the upstroke and bottom-out phases. The Neptune, while it offers a distinct blend of POM and polycarbonate, can nonetheless achieve a pleasing sound experience, thanks to POM's ability to maintain some of the characteristics found in nylon. Ultimately, the choice between the two hinges on personal sound preference; users aiming for a more muted, deep typing experience may lean towards the EVA, whereas those who appreciate a mix of clarity and depth might find the Neptune to be just as enjoyable in practice.
Weight
When comparing the HMX EVA linear switch and the TTC Neptune linear switch, both options are relatively light in actuation and bottom out forces. The EVA features an actuation force of 42 grams and a bottom out force of 48 grams, while the Neptune has an actuation force of 41 grams and a bottom out force of 50 grams. This means that the Neptune requires slightly less force to initiate a keystroke compared to the EVA, making it marginally easier to type on. However, the Neptune also has a slightly higher bottom out force. Overall, both switches provide a smoother typing experience suitable for long sessions, but users who prefer a more substantial feel may lean towards the TTC Neptune due to its higher bottom out force, while those who prioritize ease of actuation may favor the HMX EVA.
Travel distance
When comparing the travel distance of the HMX EVA linear switch and the TTC Neptune linear switch, the EVA features a travel distance of 3.6 mm, while the Neptune has a slightly longer travel distance of 3.8 mm. This indicates that the EVA switch offers a shorter travel experience, which may be beneficial for those who prioritize quick response times, such as gamers. On the other hand, the Neptune's travel distance provides a deeper feel, which some users might prefer for a more satisfying typing experience. Ultimately, choosing between these two switches comes down to personal preference regarding the depth and responsiveness of the keypress, with the EVA being the shorter option and the Neptune being the longer one.

Typing experience
When it comes to sound, the HMX EVA offers a resonant signature that potentially provides a rich auditory experience, although specific descriptors are not provided. In contrast, the TTC Neptune is characterized by a sound profile that is low-pitched, muted, and thocky. This means it produces a softer and more subdued sound compared to traditional clacky switches, akin to a deep "thud" or a soft "knock." Such a sound signature can be particularly appealing in environments where noise reduction is appreciated, giving users a satisfying auditory cue without being disruptive.
In terms of feel, the EVA is celebrated for its silky smooth typing experience, yet it lacks detailed descriptors to fully understand its unique qualities. The TTC Neptune, however, boasts a plethora of feel characteristics. It provides a buttery and frictionless typing sensation, underscoring an effortless keystroke experience. Users will also notice that the Neptune incorporates a gummy quality, which produces a unique bottoming-out sensation reminiscent of trampoline-like softness. The overall mild and polished sensations contribute to a smooth, user-friendly typing experience, making it approachable for newcomers and experienced typists alike.
In summary, both the HMX EVA and TTC Neptune linear switches have their own charm, with the EVA excelling in a silky smooth typing experience and a resonant sound signature. The Neptune, while offering a sound profile rich in thocky qualities and a muted presence, provides a superior feel with its buttery, frictionless, and gummy characteristics. Ultimately, while both switches cater to distinct preferences, users can anticipate a satisfying experience from either, particularly if they appreciate smoothness and effective sound profiles in their mechanical keyboard setup.
Conclusion
To conclude, your choice between the HMX EVA linear switch and the TTC Neptune linear switch ultimately hinges on your personal preferences and typing style. If you favor a lighter touch with a vibrant aesthetic inspired by popular culture, the EVA switch, with its 48 grams of bottom-out force and resonant sound signature, could be your ideal choice. Its smooth keystroke offers an enjoyable typing experience, particularly if you appreciate a more animated yet subtle aesthetic in your mechanical keyboard. On the other hand, if you're looking for an exceptionally smooth typing experience with a tactile sensation reminiscent of mochi and a sound profile that is muted and thocky, the Neptune switch might be more up your alley. With its slightly higher bottom-out force of 50 grams and buttery glide, the Neptune caters well to those who desire a balanced, almost frictionless typing experience that doesn't disrupt the environment around them. Both switches are designed for distinct typing experiences, so consider your priorities—whether it's visual appeal, sound, or a particular tactile feedback—before making your final decision.
