HMX Blue Topaz vs. HMX Gravel

Overview

When it comes to choosing the right mechanical keyboard switch, the HMX Blue Topaz and HMX Gravel present two distinct yet appealing options, both categorized as linear switches but differing in their feel and auditory feedback. The Blue Topaz is characterized by its super smooth actuation and lightweight design, providing an effortless typing experience complemented by a clacky sound profile that adds a playful touch to each keystroke, along with striking visual appeal due to its glittery housing. On the other hand, the HMX Gravel offers a refined typing feel with a medium-light actuation force, prioritizing a smooth and responsive experience while eliminating any clackiness, making it perfect for those who prefer a quieter typing environment. While the Blue Topaz is ideal for users seeking both auditory delight and a tactile experience, the Gravel shines for individuals who value a seamless and understated feel. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials

Both the HMX Blue Topaz and the HMX Gravel utilize polycarbonate for their top housing, resulting in a sound profile that is notably sharp, high-pitched, and crisp. The stiffer nature of polycarbonate allows for a clear and resonant auditory experience that heightens the responsiveness of key presses. This common material choice effectively enhances the overall typing experience, particularly when RGB lighting is included, as the translucence of polycarbonate optimizes the aesthetic appeal of illuminated switches. Thus, users can expect similar auditory feedback from both models when typing, thanks to the inherent qualities of polycarbonate.

Conversely, while the top housings of both the Blue Topaz and Gravel share the same polycarbonate material, they both employ nylon for their bottom housing, introducing an important contrast in the acoustic characteristics of each switch. Nylon, regarded as a classic switch housing material, brings a deeper and fuller sound profile to the typing experience. This material is notably softer than polycarbonate, causing it to absorb more sound and create a duller and rounder profile. Consequently, the bottom housing significantly influences the bottom-out sound and feel of the key, leading to a richer auditory experience during key presses, which both models will provide.

Overall, although the HMX Blue Topaz and HMX Gravel have distinct sound qualities stemming from their differing bottom housings, the commonality of polycarbonate in their top housings ensures a crisp and clear sound profile. This synergy allows users to enjoy the best of both worlds: the invigorating resonance from the polycarbonate tops and the rich, fuller sounds from the nylon bottoms. Hence, despite their differences, typing on either switch will yield a cohesive and satisfying auditory experience driven by the merits of both housing materials.

Weight

The HMX Blue Topaz and HMX Gravel linear switches both offer a relatively light typing experience, but they do differ in their actuation and bottom out forces. The Blue Topaz has an actuation force of 40 grams and a bottom out force of 48 grams, while the Gravel has slightly higher values, with an actuation force of 45 grams and a bottom out force of 50 grams. This indicates that the Blue Topaz is the lighter switch, making it potentially more suitable for users who prefer a softer touch for longer typing sessions or extended gaming. Conversely, the Gravel, with its heavier forces, may appeal more to those who enjoy a more substantial typing feel. Overall, while both switches are categorized as light, the difference in their actuation and bottom out forces could influence user preference based on desired typing experience.

Travel distance

When comparing the travel distances of the HMX Blue Topaz linear switch and the HMX Gravel linear switch, the Blue Topaz features a travel distance of 3.9 mm, while the Gravel measures at 3.5 mm. This makes the Gravel the shorter option, potentially making it more appealing to gamers and those who prioritize faster response times. On the other hand, the Blue Topaz, with its longer travel distance, may be favored by users who appreciate a more substantial tactile experience while typing. While both switches have their unique advantages, the difference in travel distance indicates that users looking for responsiveness should lean towards the Gravel, while those seeking a deeper press should opt for the Blue Topaz.

Typing experience

When it comes to sound, the HMX Blue Topaz linear switch produces a distinctive clacky sound signature. This characteristic offers a crisp, bright, and percussive auditory experience, making it particularly appealing for users who enjoy the feedback that accompanies their typing actions. On the other hand, the sound profile of the HMX Gravel switch is currently unknown, meaning that its acoustics remain a mystery. However, sound can greatly depend on individual preferences and additional factors like the keyboard's construction and keycap material, which may affect how either switch performs in practice.

Regarding feel, the HMX Blue Topaz excels with its easy-to-press design, requiring minimal force to actuate, which translates to an effortless and comfortable typing experience. The lightweight actuation a makes it less taxing on the fingers, allowing for extended typing sessions without discomfort. The HMX Gravel switch, while also designed for a smooth experience, leans towards a medium-light actuation force, suggesting that it too offers a responsive typing feel that requires some gentle resistance. This lightly tactile resistance can enhance typing precision while still facilitating a comfortable and enjoyable experience, although specific descriptors for the Gravel's tactile feedback are not provided.

In summary, the HMX Blue Topaz and HMX Gravel switches both provide a satisfying typing experience, though they do so in slightly different ways. The Blue Topaz stands out with its engaging clacky sound and ultra-light actuation, making it suitable for those who enjoy auditory feedback. Meanwhile, the Gravel's medium-light actuation is geared towards users who prefer a slightly more grounded typing experience, though its sound quality remains unestablished. Whether you prioritize sound or feel, both switches aim to enhance your overall keyboard experience with their emphasis on smoothness and responsiveness. For the most cohesive typing experience with either switch, consider your choice of keyboard construction and keycap material, as these factors will undoubtedly influence the final results.

Conclusion

To sum up, when deciding between the HMX Blue Topaz and the HMX Gravel linear switches, it ultimately comes down to your personal preferences and intended use. If you seek an ultra-smooth typing experience coupled with a lightweight feel, the Blue Topaz is your best bet. Its clacky sound signature and distinctive glittery appearance provide not just functionality but also a delightful sensory experience, making it especially great for those who enjoy tactile feedback and a bit more character in their setup. On the other hand, if you prefer a more refined and straightforward typing experience, the Gravel switches are an excellent choice. They offer a responsive feel with a slightly firmer actuation, making them suitable for longer typing sessions or for users who prefer a more muted sound profile without sacrificing smoothness. In essence, if you want a playful and engaging keyboard experience, opt for the Blue Topaz; if you seek elegance and comfort in a quieter environment, the HMX Gravel is the way to go.
