HMX Gravel vs. HMX SU

Overview

When it comes to choosing the right mechanical keyboard switch, enthusiasts often find themselves torn between options that deliver distinct experiences. The HMX Gravel and HMX SU are both linear switches designed for smooth operation, yet they cater to different preferences in typing feel and sound. The Gravel is celebrated for its exceptional smoothness and light actuation force, providing a responsive and effortless typing experience that many users find incredibly satisfying. In contrast, the HMX SU offers a full PA12 housing paired with a T5 stem, which contributes to its subtle yet relatively deep sound profile, making it an appealing choice for those who appreciate auditory feedback during their typing sessions. While both switches promise a refined experience, your choice may ultimately depend on whether you prioritize a lighter touch with the Gravel or a more acoustically rich feel with the SU. However, let’s dive in a bit deeper beyond generalities so you can best decide on the perfect switch for you.

Housing materials

When comparing the housing materials of the HMX Gravel and the HMX SU, a notable distinction lies in the composition of the top housing. The Gravel utilizes a polycarbonate top housing, renowned for its ability to produce a sharper, higher-pitched, and crisper sound profile. This is largely attributed to polycarbonate's stiffer nature, which enhances clarity and resonance. Furthermore, the translucency of polycarbonate allows for vivid RGB lighting effects, making the Gravel visually striking while delivering a sound that is distinctly articulate. In contrast, the HMX SU features a nylon top housing, a classic choice that yields a deeper and fuller sound profile. Nylon's softer characteristics promote sound absorption, resulting in a rounder and more muted auditory experience. Consequently, the differing materials used in the top housing of these switches greatly influence the overall sound quality produced during key presses, establishing a fundamental difference between the two models.

In terms of the bottom housing, both the HMX Gravel and the HMX SU employ nylon material, which produces a similar sonic profile. This shared use of nylon means that users can expect a deeper and fuller sound from the bottom housing in both switches, as nylon's sound-absorbing properties contribute to a more uniform auditory experience. Since the bottom housing significantly influences the bottom-out sound and tactile feel when a key is pressed, both switches will provide a consistent sensation that is rounded and satisfying. Here, the similarities in material ensure that despite the contrasting qualities of the top housing, the bottom housing will deliver a comparable experience across both models.

Overall, the combination of polycarbonate in the Gravel's top housing and nylon in both housings of the Gravel and SU presents a nuanced comparison of these switches. The noticeable differences in top housing material between the Gravel and SU create distinct aural effects during typing, while the uniformity of nylon in the bottom houses promotes a coherent tactile experience. Users seeking sharper, more vibrant key sounds may lean towards the Gravel, while those desiring a mellower, fuller sound might prefer the SU. However, regardless of these distinctions, the consistent impact of nylon in both bottom housings ensures that those who choose either switch will receive a satisfying typing experience, creating a bridge in performance quality that connects both models.

Weight

The HMX Gravel linear switch and the HMX SU linear switch exhibit identical specifications when it comes to both actuation and bottom out forces, with each switch requiring an actuation force of 45 grams and a bottom out force of 50 grams. This means that users can expect a consistent typing experience with easiness in actuation and a firm feedback when bottoming out, providing a light touch that is ideal for extended typing sessions or gaming. Since both switches have the same weights, users who prefer lighter options for prolonged use will find them equally suitable, while those who appreciate a stronger push feeling may not have a preference between the two. Ultimately, the similarity in actuation and bottom out forces means that performance will behave similarly, allowing users to choose either switch based on other personal preferences without sacrificing force sensitivity.

Travel distance

The HMX Gravel linear switch has a travel distance of 3.5 mm, while the HMX SU linear switch has a slightly longer travel distance of 3.6 mm. This minor difference means that the Gravel switch may provide a more responsive feel, appealing to those who prefer quicker key presses, such as gamers. In contrast, the SU switch, with its longer travel distance, could offer a more substantial feedback during key presses, which some users may find preferable for comfort and depth in typing. Ultimately, while both switches are designed for different preferences, the Gravel's shorter travel distance of 3.5 mm makes it more suitable for fast-paced activities, while the SU's 3.6 mm may cater to those who enjoy a more pronounced keystroke.

Typing experience

In terms of sound, the HMX Gravel linear switch does not have defined auditory characteristics provided, making it difficult to assess its unique sound profile compared to the HMX SU. The SU, however, is noted for its subtle yet relatively deep sound profile, which can contribute to a more satisfying auditory experience, particularly for users who appreciate a rich sound without being overly loud. Remember that the final sound output can also be influenced by factors such as the specific keyboard build, the materials of the keycaps used, and the overall environment in which the keyboard is used.

When it comes to feel, the HMX Gravel switches are celebrated for their exceptional smoothness and refined typing experience, combining a medium-light actuation force that enhances responsiveness and makes typing pleasurable. In contrast, specific details regarding the tactile feel of the HMX SU switch have not been provided, so it's difficult to compare directly. Generally, if both switches are linear, you can anticipate a relatively similar lack of tactile feedback during key presses, leading to a fluid and uninterrupted typing experience that is characteristic of linear switches.

Overall, while the HMX Gravel linear switch is highly regarded for its smooth typing feel, the HMX SU provides a unique sound signature that could appeal to users seeking a deeper auditory experience. Given that the gravel's feel is distinguished by its ease and refined touch, enthusiasts may find that both switches offer qualities that cater to different preferences. While the Gravel's sound profile remains unspecified, the SU's notable auditory characteristics can still add distinctiveness to one's typing experience. In conclusion, both switches have unique attributes that can fulfill different aesthetic and functional desires in the realm of mechanical keyboards.

Conclusion

To conclude, when deciding between the HMX Gravel linear switch and the HMX SU linear switch, your choice should be guided by your personal preferences for sound and feel. If you prioritize a smoother, more refined typing experience, the Gravel switch is an excellent option. Its light actuation force combined with an exceptional smoothness makes it perfect for extended typing sessions, particularly if you enjoy a responsive yet effortless touch. Conversely, if you’re drawn to a unique auditory experience, the HMX SU switch may serve you better with its subtly deep sound profile, which could add an enjoyable acoustic dimension to your inputs. This is especially true for those who appreciate the tactile feedback that the full PA12 housing and T5 stem provide. Consider how you type and what enhances your keyboard experience—if you crave smoothness, go for the Gravel; if you prefer a satisfying sound alongside a solid feel, the SU is the way to go. Ultimately, understanding these nuances will help you select the switch that best complements your typing style and enhances your overall enjoyment of your mechanical keyboard.
