HMX KD200 vs. TTC Neptune
An in-depth look at the HMX KD200 and the TTC Neptune switches—which one is the best fit for you?
Overview
When it comes to choosing a mechanical keyboard switch, the HMX KD200 and the TTC Neptune stand out as two compelling options for fans of linear switches, each offering a unique typing experience. The KD200 is renowned for its pronounced clackiness, making it a delightful choice for those who appreciate a more audible feedback while typing. This switch is not only characterized by its distinct sound but also provides a smooth keypress that many gamers and typists enjoy for its satisfying tactile response. In contrast, the TTC Neptune features an innovative internal design that delivers a remarkably smooth, frictionless glide paired with a springy resistance, evoking the enjoyable chewiness of mochi or tapioca pearls. Its ultralight weight allows for effortless typing, and the muted, thocky sound signature creates a more subtle auditory experience. While both switches cater to those who prefer linear feedback, the KD200 leans towards a more vibrant sound profile, whereas the Neptune offers a subtle yet rich tactile experience. However, let’s dive in a bit deeper beyond generalities so you can best decide on the right switch for you.

Housing materials
The HMX KD200 and TTC Neptune switches utilize different materials for their top and bottom housings, leading to distinct sound profiles while also sharing some similarities in their acoustic characteristics. The KD200's top and bottom housings are made of nylon, known for its ability to produce a deeper and fuller sound due to its softer properties that absorb more sound waves. This results in a duller and rounder audio output, which enhances the typing experience by delivering a smooth and muted sound profile. In contrast, the TTC Neptune features a POM top housing, which provides a unique sound that is also on the deeper side but comparatively more muted. The differences in materials imply that while both switches may achieve a full sound, the means by which they do so varies significantly.
On the bottom housing front, the KD200 maintains its consistent use of nylon, further emphasizing its overall sound qualities. By allowing the softer plastic to absorb sound, the KD200 creates a cohesive and harmonious sound signature that contributes to a muted auditory experience. The Neptune’s polycarbonate bottom housing, on the other hand, introduces a sharper and crisper sound profile. Polycarbonate is typically known for its rigidity, which creates a more clear and resonant sound, differing greatly from the muted effect of nylon. Although the KD200 aims for a uniform sound experience from top to bottom, the Neptune’s combination of a POM top and polycarbonate bottom creates a dynamic contrast, allowing for varied auditory feedback depending on which part of the switch is being engaged.
Ultimately, even with their differing materials and the resulting effects, both the HMX KD200 and the TTC Neptune can still deliver satisfying typing experiences. Users who prefer a softer sound might gravitate towards the KD200, while those seeking a sharper and brighter auditory feedback might prefer the Neptune. However, if one were to harmonize the effects, the KD200's cohesive nylon materials would yield a consistently muted profile, while the Neptune's hybrid nature provides a more innovative approach by blending characteristics of different plastics. Consequently, although the switches differ in construction, they can still lead to enjoyable typing experiences through carefully balanced sound qualities and tactile feedback tied to the individual transitions of each housing material.
Weight
When comparing the HMX KD200 linear switch and the TTC Neptune linear switch, both offer light actuation and bottom out forces, making them suitable for extended typing sessions. The KD200 has an actuation force of 45 grams and a bottom out force of 50 grams, while the Neptune features a lighter actuation force of 41 grams, also bottoming out at 50 grams. While both switches share the same bottom out force, the Neptune provides a lighter feel upon actuation, which can enhance comfort and reduce finger fatigue during long periods of use. Conversely, those who prefer a more substantial typing experience might lean towards the slightly heavier KD200 switch for its stronger actuation force. Ultimately, both switches deliver similar bottom-out experiences, but the KD200 may appeal more to individuals favoring a firmer tactile sensation.
Travel distance
When comparing the travel distance of the HMX KD200 linear switch and the TTC Neptune linear switch, a notable difference emerges: the KD200 features a travel distance of 3.5 mm, while the Neptune has a slightly longer travel distance of 3.8 mm. This means that users of the KD200 may experience a quicker response time, making it ideal for gamers who favor faster actuation. On the other hand, the Neptune, with its longer 3.8 mm travel distance, may provide a more substantial feel, catering to those who prefer a more deliberate and hearty keypress. Ultimately, the choice between these two switches will depend on personal preference; the KD200 offers a shorter and potentially more responsive option, while the Neptune provides a longer throw for a more pronounced typing experience.

Typing experience
The sound profile of the HMX KD200 linear switch is defined by its clackiness, making it one of the more pronounced options available. It generates a sharp and bright acoustic response that can be quite satisfying for those who enjoy auditory feedback while typing. In contrast, the TTC Neptune switch presents a more muted and subdued sound with its low-pitched and thocky characteristics, resulting in a deep, rich tone that feels more inviting for quieter environments. This low-key resonance is ideal for users who prefer typing without drawing too much attention, as the Neptune minimizes the noise typically associated with mechanical keys, offering a more mellow auditory experience.
When considering the feel of each switch, the KD200's tactile response isn't explicitly detailed in this context, leaving some room for interpretation. The Neptune switch, however, is notably defined by its buttery and frictionless qualities, which contribute to a remarkably smooth typing experience. Users will appreciate the gummy sensation that accompanies the bottoming out, offering a unique experience akin to tapping on a trampoline. The Neptune's characteristics provide an effortless glide while typing, resulting in minimal resistance at every keystroke, making it ideal for prolonged typing sessions.
In summary, while the HMX KD200 linear switch is geared towards those who enjoy a more auditory and lively typing experience, the TTC Neptune linear switch caters to individuals seeking a quieter and smoother interaction with their keyboard. The contrast between the clackiness and thockiness of the two switches underscores the diverse preferences among users, with the Neptune’s unique feel enhancing its appeal for effortless typing. Ultimately, each switch brings its own charm to the table, allowing users to choose based on their auditory and tactile preferences for an optimal typing environment.
Conclusion
To conclude, your choice between the HMX KD200 linear switch and the TTC Neptune linear switch will largely depend on your personal preferences regarding sound and typing feel. If you appreciate a more clacky typing experience and enjoy the vibrant auditory feedback that can energize your typing sessions, the KD200 may be the ideal choice for you. Its light actuation force ensures easy keystrokes, making it suitable for fast typists or those who enjoy a more expressive keystroke. On the other hand, if you prefer a typing experience that is smooth and refined, similar to the gentle bounce of mochi or the soft glide of tapioca pearls, the TTC Neptune should be your go-to switch. Its muted and thocky sound signature, combined with its frictionless feel, creates a satisfying yet subtle experience—perfect if you work in shared spaces or simply prefer a quieter environment. Ultimately, your decision hinges on whether you prioritize a fun and lively sound or a more serene and polished typing experience.
