HMX SU vs. Gateron Zero Degree 0°
An in-depth look at the HMX SU and the Gateron Zero Degree 0° switches—which one is the best fit for you?
Overview
When it comes to choosing a mechanical keyboard switch, the HMX SU and the Gateron Zero Degree 0° linear switches offer distinct characteristics that cater to different typing preferences. The HMX SU, with its full PA12 housing and T5 stem, is known for a subtle yet relatively deep sound profile, providing a satisfying acoustic experience while you type. Its design emphasizes a smooth linear action that may appeal to gamers and typists alike who appreciate a more pronounced tactile sensation. On the other hand, the Gateron Zero Degree 0° sets a new benchmark for silent operation with its unique self-padding design and dual-rail structure, ensuring unparalleled smoothness and stability. This switch combines a muted, low-pitched sound with a soft, elastic feel, making it ideal for those seeking a quieter workspace without sacrificing performance. Both switches have their strengths—whether you value a textured sound experience or prioritizing silence and smoothness in your typing environment. 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 SU and the Gateron Zero Degree 0°, a clear distinction arises in the choice of top housing materials. The HMX SU features a nylon top housing, known for its ability to produce a deeper and fuller sound profile due to its softer plastic composition. This allows the nylon to absorb sound more effectively, leading to a more muted and rounded auditory experience when typing. In contrast, the Gateron Zero Degree 0° utilizes polycarbonate for its top housing, which is a much stiffer plastic. This leads to a sharper, higher-pitched, and more resonant sound profile, appealing to those who prefer a crisper typing experience. The translucency of polycarbonate also offers aesthetic advantages, particularly for users looking to incorporate RGB lighting in their setups, as it allows light to pass through more effectively.
On the other hand, both switches employ nylon for their bottom housing, lending them a shared characteristic that impacts their overall sound. The nylon material in the bottom housing of both the HMX SU and the Gateron Zero Degree 0° contributes to a deeper and fuller sound profile, helping to drown out sharper auditory peaks that might be introduced by their respective top housings. This means that, despite the differences in their top housing materials, users of both switches will still experience a certain level of sound consistency at the bottom of the stroke, where the nylon helps to cushion the impact and retain that richer auditory quality.
Ultimately, when considering the combined effects of the materials used in both the top and bottom housings, the HMX SU and Gateron Zero Degree 0° offer contrasting experiences primarily from the top housing. The nylon top of the SU produces a duller sound, while the polycarbonate of the Zero Degree 0° provides a pronounced crispness. However, the shared nylon composition of their bottom housings ensures that both switches maintain a certain harmony in sound and feel at the bottom-out point. This balance allows users to appreciate the unique attributes of each switch while still enjoying an overlap in auditory richness thanks to the nylon's inherent sound-dampening properties.
Weight
When comparing the HMX SU linear switch to the Gateron Zero Degree 0° linear switch, both switches exhibit the same actuation force of 45 grams, indicating that they require the same amount of pressure to trigger a keystroke. This similarity suggests that users will experience comparable responsiveness when pressing down on either switch. However, the bottom out force provides a point of differentiation; the SU switch has a defined bottom out force of 50 grams, giving it a slightly heavier overall feel once the key is fully pressed down. In contrast, the Zero Degree's bottom out force remains unknown, leaving its overall tactile experience ambiguous. Given that the SU switch is confirmed to have a heavier bottom out feel, it may appeal more to those preferring a substantial typing experience. Meanwhile, the actuation forces being the same means that both switches will support extended usage without significantly impacting fatigue—ideal for long typing sessions. Thus, while both switches share a light actuation, the HMX SU offers a heavier bottom out force, distinguishing it for users who appreciate a more robust response.
Travel distance
Both the HMX SU linear switch and the Gateron Zero Degree 0° linear switch have an identical travel distance of 3.6 mm. This means that when pressing down a key on either switch, users will experience the same distance before reaching the bottom, providing a uniform feel in terms of key actuation. Since both switches share the same travel distance, you can expect similar tactile responses and performance, making them equally compatible for users seeking a consistent typing experience.

Typing experience
When it comes to sound, the HMX SU linear switch is renowned for its subtle yet relatively deep sound profile, offering a satisfying acoustic experience tailored for users who appreciate a rich tone without being overly loud. Its full PA12 housing contributes to this acoustic depth. Conversely, the Gateron Zero Degree 0° linear switch features a design that prioritizes sound dampening. With its low-pitched, muted characteristics, the Zero Degree 0° provides a quiet typing experience, ideal for those who type in shared spaces or prefer a more subdued sound profile. This switch absorbs noise thanks to its innovative design elements, making it a sound-sensitive choice for users wanting to minimize any disruption.
In terms of feel, the HMX SU linear switch maintains a balanced tactile experience, characterized by a gentle yet noticeable resistance that allows for an enjoyable typing rhythm. Its construction includes a T5 stem, ensuring a consistent and stable feel across keystrokes. On the other hand, the Gateron Zero Degree 0° linear switch is designed with user comfort in mind, featuring a polished feel that promotes smoother key travel. The soft, elastic nature of this switch contributes to a refined typing experience while maintaining a light enough touch to prevent fatigue during extended use. Notably, the Zero Degree 0° switch’s subtle resistance allows for a more effortless interaction, favoring those who prioritize a quieter and refined typing experience.
Overall, both the HMX SU and Gateron Zero Degree 0° linear switches offer distinct auditory and tactile experiences tailored for different preferences. The SU provides a deeper, more resonant sound alongside a balanced feel, making it great for users who enjoy a little more feedback in their typing. In contrast, the Gateron Zero Degree 0° excels in delivering a muted sound and a polished, smooth sensation, appealing to users who value quiet and a luxurious touch. Depending on what aspect you prioritize—sound or feel—both switches can deliver satisfying results in their own right, ensuring that newcomers to mechanical keyboards can find an option that suits their typing needs.
Conclusion
To sum up, the choice between the HMX SU linear switch and the Gateron Zero Degree 0° linear switch ultimately depends on your personal preferences and typing environment. If you prefer a switch with a lighter actuation force of 50 grams and enjoy a subtle, deep sound profile that provides a bit of character while typing, the HMX SU may be your best option. This switch is well-suited for those who appreciate a tactile experience with a moderate sound level that won’t be overly intrusive. On the other hand, if you are looking for a switch that offers an ultra-smooth typing experience with an emphasis on silence, then the Gateron Zero Degree 0° should be your go-to. Its innovative self-padding design and dual-rail structure deliver a polished and stable feel, perfect for use in shared spaces, ensuring your keystrokes are barely heard. Ultimately, consider your typing style, sound preferences, and the environment in which you’ll be using the keyboard to make the best choice for your needs.
