HMX 1989 vs. HMX Xinhai (Heavy)
An in-depth look at the HMX 1989 and the HMX Xinhai (Heavy) switches—which one is the best fit for you?
Overview
When choosing the right mechanical keyboard switch, the HMX 1989 and the HMX Xinhai (Heavy) are both excellent linear options that each offer distinct characteristics catering to different user preferences. The HMX 1989 is celebrated for its deep, thocky sound profile, making it a favorite among gamers and typists who appreciate a more pronounced auditory feedback. On the other hand, the HMX Xinhai (Heavy) boasts a heavier feel with a unique PA12 top housing that provides softer acoustics, along with a POM stem that delivers a crisp, higher-pitched resonance—ideal for those who prefer a blend of elegance and performance. While both switches offer smooth keystrokes without tactile bumps, your preference may lean towards the satisfying thock of the HMX 1989 for an immersive gaming experience, or the refined sound and weight of the HMX Xinhai (Heavy) for a more sophisticated typing experience. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The housing materials of the HMX 1989 and the HMX Xinhai (Heavy) serve distinct purposes in crafting the auditory experience of each switch, primarily due to their differing choices for the top housing. The HMX 1989 utilizes a polycarbonate top housing, which is known for producing a sharper, higher-pitched, and crisper sound profile. The stiffer nature of polycarbonate allows for clearer resonance, making it predominantly favorable for those seeking an expressive sound, especially when RGB lighting is considered, as the material's translucency enhances the visual appeal. Conversely, the Xinhai (Heavy) features a nylon top housing. Nylon’s softer composition results in a rounded, deeper sound profile, as it absorbs more sound, leading to a more muted but full auditory experience. Here, the contrast in the material directly affects the sound characteristics, with the polycarbonate resulting in a brighter, more dynamic performance compared to the warmer tones of nylon.
In terms of the bottom housing, both the HMX 1989 and the Xinhai (Heavy) utilize nylon, which serves as a commonality in achieving a deeper and fuller sound profile. The choice of nylon for the bottom housing ensures consistency in sound dampening capabilities, as both switches will create a duller sound when bottoming out. This similarity fosters a baseline of auditory quality shared between both models. While the HMX 1989 imparts its distinctive resonance through its unique polycarbonate top, the Xinhai (Heavy) leans into its softer, fuller sound experience with both housings composed of nylon. This indicates that while their tops contrast in material and sound signature, a unified element exists within their bottoms.
Ultimately, the differences and similarities in materials between the HMX 1989 and the Xinhai (Heavy) impact the overall sound experience of each switch. The top housing's material significantly influences the sound profile upon key release, while both switches share the qualities of nylon in their bottom housing, enhancing the bass quality and dampening the acoustic output. Consequently, while the auditory experiences provided by the two switches differ primarily due to the top housing material, the similar bottom housing ensures a coherent sound foundation that contributes to a rich typing experience across both designs. This allows users to derive some consistent auditory qualities even if their top housing leads to divergent acoustic characteristics.
Weight
When comparing the HMX 1989 linear switch and the HMX Xinhai (Heavy) linear switch, their actuation and bottom out forces reveal their distinct characteristics tailored to different user preferences. The HMX 1989 has an actuation force of 45 grams and a bottom out force of 53 grams, making it a medium-light option that is suited for prolonged typing sessions and gaming, as it requires less force to trigger each keystroke. In contrast, the Xinhai (Heavy) features a higher actuation force of 55 grams and a bottom out force of 62.5 grams, categorizing it as a heavier switch that provides a more substantial typing feel, appealing to users who enjoy a stronger push back. Consequently, the HMX 1989 is the lighter option, better for those who type or game for extended periods, whereas the HMX Xinhai (Heavy) offers a firmer experience that may be preferred by users seeking more tactile feedback. Both switches, while designed for different weights and forces, ultimately cater to varied typing preferences based on individual comfort levels with actuation and bottom out forces.
Travel distance
When comparing the travel distances of the HMX 1989 linear switch and the HMX Xinhai (Heavy) linear switch, there is a notable difference: the 1989 has a travel distance of 4 mm, while the Xinhai (Heavy) measures 3.4 mm. This makes the 1989 the longer option, providing a more pronounced tactile experience that some users may prefer for a satisfying key press. On the other hand, the Xinhai (Heavy) offers a shorter travel distance, which can lead to quicker response times, appealing to gamers or those who prioritize speed. Thus, if a lighter and more responsive feel is desired, the Xinhai (Heavy) would be the recommended choice. Conversely, for users who appreciate a deeper engagement with their keystrokes, the HMX 1989 would be more suitable.

Typing experience
The HMX 1989 linear switch is well-regarded for producing a deep and thocky sound profile, which is often favored by enthusiasts who enjoy a satisfying auditory feedback while typing or gaming. The richness of its sound can create an engaging atmosphere, enhancing the typing experience. In contrast, the HMX Xinhai (Heavy) switch offers a distinctively crisp and higher-pitched resonance, attributed to its unique PA12 top housing and POM stem. This combination results in a softer acoustics profile that allows for a more subtle yet refined audio experience. Both switches can create varying sound dynamics based on the board and keycap selection, but their core audio qualities are remarkably different.
When considering the feel of each switch, the HMX 1989 is celebrated for its deep and thocky response, providing a strong tactile sensation that some users find pleasing and immersive during extended typing sessions. Conversely, the HMX Xinhai (Heavy) emphasizes a blend of subtle sophistication and precise performance, likely delivering a different tactile feedback that caters to users who appreciate a more refined touch. Although both switches are linear in nature, their differing characteristics could lead to unique experiences for the typist based on personal preference.
In conclusion, both the HMX 1989 and Xinhai (Heavy) linear switches offer distinctive sound and feel qualities that cater to different user preferences. The 1989 excels in its deep, thocky acoustics and strong tactile feedback, appealing to those who favor a robust typing experience. On the other hand, the Xinhai (Heavy) provides a softer sound and a more nuanced feel, making it suitable for someone seeking a greater level of subtlety in their keystrokes. Ultimately, your choice between these switches will depend on the sound and feel that align best with your typing preferences.
Conclusion
To conclude, your choice between the HMX 1989 linear switch and the HMX Xinhai (Heavy) linear switch ultimately depends on your personal preferences regarding actuation force, sound, and overall typing experience. If you favor a lighter bottom-out force and a deeper thocky sound profile, the 1989 is likely to suit you best, especially if you're into activities that benefit from quicker actuation, such as gaming. Its medium-light pressure makes it a fantastic option for extended typing sessions, as it reduces finger fatigue. On the other hand, if you prefer a firmer tactile response and the subtlety of a higher pitch when you type, the Xinhai (Heavy) is an excellent choice. With its robust 62.5 grams of force, this switch offers a more deliberate feel that is beneficial for roles requiring precision, such as programming or writing. The unique housing design ensures a crisp acoustic signature that enhances the typing experience for users who appreciate that sound profile. Ultimately, it’s about aligning your choice with your typing style and sound preference to enhance your overall mechanical keyboard experience.
