Outemu Crystal vs. HMX Xinhai
An in-depth look at the Outemu Crystal and the HMX Xinhai switches—which one is the best fit for you?
Overview
When considering mechanical keyboard switches, the Outemu Crystal and the HMX Xinhai both offer unique benefits for different typing preferences. The Crystal provides a linear typing experience with a fairly elastic feel and medium-light weight, resulting in a smooth and consistent keystroke. Its neutral sound profile makes it ideal for those who prefer a quieter typing experience. On the other hand, the Xinhai switch boasts a softer acoustics profile with a distinctively crisp, higher-pitched resonance thanks to its unique PA12 top housing and POM stem. This switch offers a blend of subtle sophistication and precise performance, making it a great choice for those who enjoy a bouncier and clackier typing feel. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The Outemu Crystal and HMX Xinhai both feature polycarbonate top housings, which offer a sharper, higher-pitched, and crisper sound profile due to the relatively stiffer nature of polycarbonate. This material is ideal for switches that incorporate RGB lighting, as the translucency of polycarbonate allows for vibrant light to shine through. In contrast, the Xinhai's nylon bottom housing provides a deeper and fuller sound profile, absorbing more sound than polycarbonate to create a duller and rounder sound. It is interesting to note how the choice of housing material can impact the overall typing experience, with the top and bottom housings each contributing distinct qualities to the sound and feel of the switch.
While both the Crystal and Xinhai utilize polycarbonate in their top housings, the Xinhai stands out with its nylon bottom housing. This contrast in materials results in a unique typing experience for each switch, with the Crystal offering a sharper sound profile while the Xinhai delivers a deeper and fuller sound. The stiffer nature of polycarbonate in the top housing of both switches creates a clear and resonant sound profile, making them suitable choices for users looking for a crisp typing experience. On the other hand, the softer nature of nylon in the Xinhai's bottom housing absorbs more sound, resulting in a rounder and duller sound that may appeal to those seeking a quieter typing experience.
Overall, the choice of housing materials in the Outemu Crystal and HMX Xinhai highlights the importance of considering the impact of polycarbonate and nylon on sound profiles and typing feel. While both switches offer unique qualities, such as the sharpness of polycarbonate and the depth of nylon, users can tailor their typing experience based on their preferences for sound and feel. Whether opting for the sharper and crisper sound of the Crystal or the deeper and fuller sound of the Xinhai, each switch provides a distinct typing experience that caters to different preferences in terms of sound profile and feel.
Weight
When comparing the actuation force and bottom out force of the Outemu Crystal linear switch and the HMX Xinhai linear switch, it is evident that the Xinhai is lighter in both aspects. The Crystal has an actuation force of 45 grams and a bottom out force of 55 grams, making it medium-light in comparison to the Xinhai, which has an actuation force of 37 grams and a bottom out force of 45 grams, categorizing it as light. The lighter weight of the Xinhai may appeal to users looking for a smoother and more effortless typing experience, allowing for extended use without fatigue. On the other hand, the slightly heavier actuation and bottom out force of the Crystal may provide users with a more substantial and tactile typing feedback. Ultimately, the choice between the two switches will depend on individual preference for typing feel and desired level of force required for keystrokes.
Travel distance
When comparing the travel distance of the Outemu Crystal linear switch and the HMX Xinhai linear switch, it is evident that the Crystal has a longer travel distance of 4 mm compared to the Xinhai's 3.4 mm. The difference of 0.6 mm may not seem significant, but it can have a noticeable impact on the typing experience. If you prefer a deeper key press with more travel distance, the Outemu Crystal switch would be the better option. On the other hand, if you prefer a shallower key press for faster response times, the HMX Xinhai switch would be the preferred choice. Both switches offer different tactile experiences, so it ultimately comes down to personal preference.

Both switches offer distinct sound profiles that can enhance the overall typing experience, depending on personal preference and the accompanying keyboard and keycaps.
Moving on to feel, the Outemu Crystal switch is known for its polished finish, resulting in a smooth and refined typing experience with reduced friction and smooth key travel. In contrast, the HMX Xinhai switch offers a bouncy and creamy sensation, providing a spring-like or elastic feedback along with a smooth and buttery feel when typing. These different tactile attributes can cater to individual preferences for typing feel, offering a variety of sensations to choose from.
In conclusion, while the Outemu Crystal and HMX Xinhai linear switches offer different sound and feel profiles, both switches provide a unique typing experience with their respective qualities. Whether you prefer a chirpy and polished typing experience with the Crystal switch or a clacky and bouncy feel with the Xinhai switch, both options offer a range of subjective qualities that can cater to various typing preferences. Ultimately, choosing between these switches will depend on personal preference in terms of sound, feel, and overall typing experience.
Conclusion
Therefore, when choosing between the Outemu Crystal linear switch and the HMX Xinhai linear switch, consider the factors that are most important to you. If you prefer a medium-light bottom out force and a neutral sound profile with a slightly chirpy and high-pitched tone, as well as a polished and refined feel, the Outemu Crystal switch may be the better option for you. On the other hand, if you prefer a lighter bottom out force, a unique acoustics profile with a clacky and sharp sound, and a bouncy or creamy feel with a softer touch, then the HMX Xinhai switch would be the ideal choice. Ultimately, your decision should be based on your personal preferences in typing experience.
