TTC Neptune vs. HMX SU
An in-depth look at the TTC Neptune and the HMX SU switches—which one is the best fit for you?
Overview
When it comes to choosing the right mechanical keyboard switch, the TTC Neptune and the HMX SU both stand out as excellent linear options, each with its unique characteristics. The TTC Neptune switch is celebrated for its innovative internal structure, providing a smooth, almost frictionless typing experience that is complemented by a springy resistance akin to the delightful chewiness of mochi or tapioca pearls. This ultralight switch allows for rapid, effortless keystrokes while producing a muted and thocky sound signature that many users find satisfying. In contrast, the HMX SU, housed in durable PA12 material and equipped with a T5 stem, offers a subtly deeper sound profile while still delivering a smooth linear feel. The depth and solidity of the SU provide a different auditory experience, appealing to those who prefer a more pronounced acoustic feedback. Ultimately, if you value a light touch and a softer soundscape, the Neptune might be your best bet, while the SU may be ideal for those seeking a more robust and resonant typing experience. However, let's dive in a bit deeper beyond generalities so you can best decide on the switch that suits your individual preferences.

Housing materials
When comparing the housing materials of the TTC Neptune and the HMX SU, it's evident that they feature distinct compositions for the top and bottom housings, which affect their overall sound profiles. The Neptune utilizes a POM top housing that is noted for creating a more muted and deeper sound. This unique sound profile is attributed to the POM's material properties, which yield a smoother acoustic experience. In contrast, the HMX SU employs a nylon top housing, which also produces a deeper sound but with a fuller resonance. While both materials contribute to a rounded sound, the softness of nylon allows for more sound absorption, resulting in a quieter, more subdued typing experience compared to the Neptune's POM.
Examining the bottom housings reveals another contrast between the two switches. The Neptune features a polycarbonate bottom housing that delivers a sharper, higher-pitched, and crisper sound, thanks to the rigidity of the polycarbonate material. This allows for a more resonant sound profile that particularly enhances the sound for RGB lighting setups, making the switch visually appealing when illuminated. On the other hand, the HMX SU incorporates a nylon bottom housing, similar to its top housing, which ensures a consistently fuller and deeper sound signature. The use of nylon here reinforces the overall muted acoustic qualities of the SU, leading to a cohesive and enveloping sound experience while maintaining the characteristics predominantly influenced by the bottom housing.
In conclusion, while the TTC Neptune and HMX SU both aim for deeper sound profiles, their differing materials—POM and polycarbonate versus nylon—lead to unique auditory results. The layered construction allows for the individual sonic traits of each housing material to manifest distinctly during operation. Despite these differences, employers can still achieve similar overall sound characteristics in both switches. This is particularly true during typing as each switch produces a satisfying sound signature; the more muted output of the Neptune and the fuller tone of the SU complement each other, showcasing the intriguing interplay between their respective housing materials. Thus, even with varied compositions, an overlapping aesthetic and functional experience can be crafted by considering how each material affects the two phases of a keystroke.
Weight
When comparing the TTC Neptune linear switch and the HMX SU linear switch, both options are characterized by relatively light force requirements, making them suitable for prolonged typing and gaming sessions. The Neptune features an actuation force of 41 grams and a bottom out force of 50 grams, while the SU requires a slightly heavier actuation force of 45 grams while maintaining the same bottom out force of 50 grams. This means that although both switches reach the same bottom out pressure, the Neptune offers a lighter touch at the point of actuation, which may appeal to those who prefer less resistance when typing. In contrast, the HMX SU linear switch, being heavier in actuation force, may provide a more substantial feel that some users seek for feedback during typing. Ultimately, while both switches deliver similar bottom out experiences, the TTC Neptune would be more suitable for users looking for lightweight options, whereas the HMX SU caters to those who prefer a more tactile typing experience with its additional weight.
Travel distance
When comparing the travel distances of the TTC Neptune linear switch and the HMX SU linear switch, it is evident that the Neptune offers a longer travel distance of 3.8 mm, while the SU features a slightly shorter distance of 3.6 mm. This difference, albeit small, signifies that the Neptune provides a more pronounced key press experience, which some users might favor for a heartier feel, particularly those who prefer the traditional depth associated with longer travel distances. On the other hand, the HMX SU's shorter distance may appeal to gamers and those who prioritize rapid response times over tactile feedback, aligning it more with contemporary preferences for quicker actuation. Thus, if you seek a balance between responsiveness and depth, you may find value in the longer travel distance of the Neptune switch. However, if you lean towards a faster, more abrupt feel, the HMX SU would be the ideal choice.
