HMX Jelly vs. TTC Neptune
An in-depth look at the HMX Jelly and the TTC Neptune switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, enthusiasts often find themselves torn between options like the HMX Jelly and the TTC Neptune, both of which are linear switches delivering smooth typing experiences. The HMX Jelly is celebrated for its low-pitched, thocky sound and remarkably lightweight actuation force of just 42g, complemented by excellent factory lubrication that ensures a silky-smooth keystroke. On the other hand, the TTC Neptune switch boasts an innovative internal structure that creates a frictionless glide while providing a delightful chewy resistance, akin to the texture of mochi or tapioca pearls. This switch, too, produces a muted yet thocky sound profile and is ultralight for effortless typing. Both the Jelly and Neptune cater to different preferences within the linear switch category—whether you gravitate towards the Jelly's distinctly deep and thocky resonance or the Neptune's unique tactile experience. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
When comparing the housing materials of the HMX Jelly and the TTC Neptune, we see distinct differences that contribute to their overall sound profiles and tactile experiences. The Jelly employs nylon for both its top and bottom housings. Nylon is known for its softer texture, which helps to create a deeper and fuller sound profile that is rounded and muted. This characteristic allows for a typing experience that minimizes harsh sounds, making it ideal for those who prefer a more subdued auditory feedback while typing or gaming. The Jelly’s consistent use of nylon in both the top and bottom enhances this effect, ensuring a cohesive sound experience as both components contribute to the overall sound.
In contrast, the TTC Neptune utilizes POM for its top housing and polycarbonate for the bottom housing. POM is a type of plastic renowned for its durability and pleasant acoustics, contributing to a unique and deeper sound profile, albeit with a slightly different texture compared to nylon. The Neptune’s bottom housing, made of polycarbonate, introduces a sharper and crisper sound, leading to a more resonant typing experience. This dual-material approach allows the Neptune to create a differentiated auditory feedback where the top housing provides a muted sound while the bottom housing offers a more pronounced, clearer resonance. Such variations may appeal to users seeking a dynamic auditory experience influenced by the different acoustic properties of the materials used.
Despite these differences, both switches will produce satisfying results tailored to distinct preferences. While the Jelly leans towards a softer, warm sound due to its homogeneous nylon construction, the Neptune offers a more pronounced, multi-faceted sound experience with its combination of POM and polycarbonate. Users looking for a vibrant, engaging typing experience may prefer the Neptune, while those desiring a milder and more contained sound might find the Jelly more appealing. Regardless of the differences in material, enthusiasts can appreciate the nuanced ways in which each switch's unique housing contributes to the soundscape of their keyboard experience.
Weight
When comparing the HMX Jelly linear switch and the TTC Neptune linear switch, both exhibit light actuation and bottom out forces, making them suitable for extended typing sessions or gaming. The Jelly switch features an actuation force of 42 grams and a bottom out force of 48 grams, while the Neptune switch has a slightly lighter actuation force of 41 grams and a slightly heavier bottom out force of 50 grams. Although both switches are light, the Jelly is marginally heavier in terms of actuation force, whereas the Neptune is heavier at bottoming out. Users seeking a more cushioned feel may prefer the Neptune for its slightly lower actuation force, while those looking for a more substantial feedback when bottoming out may lean towards the Jelly. Overall, these switches provide different tactile experiences while remaining within the light force category, appealing to a broad range of preferences among typists and gamers alike.
Travel distance
Both the HMX Jelly linear switch and the TTC Neptune linear switch have a travel distance of 3.8 mm, resulting in a similar feel when pressing down on a key. Since both switches share this exact travel distance, users can expect equivalent tactile feedback and actuation depth during use. This similarity in travel distance ensures that performance in terms of key responsiveness will be comparable, making either switch a suitable choice for those who prefer a consistent linear key experience.

Typing experience
In terms of sound, the HMX Jelly linear switch produces a low-pitched, deep, thocky sound signature that is notably satisfying and rich, making it appealing for users who enjoy a substantial auditory feedback with each keystroke. In comparison, the TTC Neptune switch also delivers a muted, thocky sound, which maintains that deep, rich quality while being softer and more subdued than more traditional mechanical switches. This makes both the Jelly and Neptune switches favorable for those seeking a quieter typing experience without compromising on sound richness, although the Jelly’s thocky sound may have a more pronounced depth.
When considering the feel, the Jelly switch is characterized by its super smooth keystrokes, aided by excellent factory lube, alongside a lightweight actuation force of 42g that allows for effortless typing. On the other hand, the TTC Neptune features an innovative internal design that promotes a frictionless glide, resembling a springy, chewy sensation akin to mochi. This results in a fluid typing experience that feels polished and buttery. While the Jelly gives a more traditional smoothness, the Neptune offers a unique tactile experience with its gummy, springy feedback, catering to those who might enjoy a different kind of tactile stimulation when typing.
Overall, both the HMX Jelly and TTC Neptune linear switches cater to users who value smoothness and satisfying sound profiles in their typing experience. While the Jelly excels in its deep thock and fluid keystrokes, the Neptune offers a lighter, more playful feel with its frictionless and gummy qualities, yet still maintains a muted thocky sound. Ultimately, choosing between these switches will depend on personal preference regarding sound depth and the specific typing sensation desired, as both will deliver a high-quality experience in their own right.
Conclusion
To conclude, your choice between the HMX Jelly linear switch and the TTC Neptune linear switch largely depends on your personal typing preferences and intended use case. If you prioritize a lighter touch and seek a super smooth keystroke experience, the HMX Jelly, with its 42g actuation force and low-pitched, thocky sound signature, might be the ideal switch for you. This makes it particularly suitable for those who enjoy a satisfying yet effortless typing experience, whether for long writing sessions or gaming where rapid key presses are essential. On the other hand, if you prefer a slightly heavier feel with a chewy, springy resistance and a muted sound, then the TTC Neptune could be your better choice. Its unique internal structure offers a buttery typing experience that many find enjoyable, allowing for a plush-feeling feedback with every keystroke. Ultimately, consider whether you want a more lightweight and unobtrusive typing sensation or prefer the slightly more weighty and textured experience of the Neptune, as both switches have their own unique character that can significantly impact your day-to-day usage.
