HMX Xinhai vs. TTC Yunhai
An in-depth look at the HMX Xinhai and the TTC Yunhai switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, the choice often boils down to personal preference, and two compelling options are the HMX Xinhai and the TTC Yunhai, both linear switches that cater to different typist desires. The Xinhai switch is celebrated for its unique PA12 top housing, resulting in softer acoustics and a POM stem that produces a crisp, higher-pitched resonance. This switch embodies a blend of subtle sophistication with performance, characterized by its bouncy, clacky, and creamy tactile feedback. On the other hand, the Yunhai excels in delivering a unique typing experience, featuring a deep, rounded sound profile that is complemented by its incredibly light actuation force, making it ideal for users who enjoy a gentler, almost feathery touch. While both switches offer distinct advantages catered to specific typing preferences, the Xinhai may appeal more to those seeking specific auditory feedback, while the Yunhai caters to those who favor effortless keystrokes. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The HMX Xinhai and TTC Yunhai switch housings utilize nylon for both their top and bottom components, reflecting a shared standard in materials that contributes to their sound and tactile performance. Nylon is reputed for its softer texture compared to harder plastics, leading to a deeper and fuller sound profile in keyboard switches. This quality is particularly notable in both models, where the material effectively absorbs sound waves, resulting in a sound that is not only quieter but also mellower. As a result, users of both switches can expect a similar auditory experience marked by a duller and rounder sound compared to other materials, making nylon a classic choice among enthusiasts seeking a certain acoustic character in their typing experience.
Despite their shared use of nylon, the HMX Xinhai and TTC Yunhai may differ subtly in how they achieve their full potential due to potential variations in other design aspects. The bottom housing has a significant impact on the bottom-out sound and feel of a switch, while the top housing primarily influences the sound produced when the key is released. If there were distinctions between the two models, such as differences in the design or configuration of these housings, users could experience varying acoustic signatures or tactile feedback. However, since both models use nylon throughout, the overall sound quality remains remarkably consistent, reinforcing the notion that the material plays a vital role in shaping the experiences of users across both switch types.
Overall, both the HMX Xinhai and TTC Yunhai stands out in the keyboard market as exemplars of nylon's capabilities in switch design, delivering on sound quality and tactile response perceived by users. The uniform use of nylon ensures that both models offer a satisfying experience characterized by that characteristic deep sound profiling which many enthusiasts cherish. Thus, even in the presence of subtle divergences in design or manufacturing nuances, the fundamental acoustic attributes stemming from nylon’s composition create a cohesive auditory experience, allowing a potential user to enjoy a similar typing sensation with either switch.
Weight
The HMX Xinhai linear switch and the TTC Yunhai linear switch, while both categorized as light switches, exhibit differences in their actuation and bottom out forces. The Xinhai features an actuation force of 37 grams and a bottom out force of 45 grams, whereas the Yunhai has slightly higher specifications with an actuation force of 42 grams and a bottom out force of 50 grams. This indicates that the Xinhai is the lighter option, offering a softer keystroke for those who prefer a more effortless typing experience. In contrast, the Yunhai, being heavier, provides a more substantial push feel, which some typists may favor for improved feedback during typing. While both switches are light, the distinction in their actuation and bottom out forces allows users to select a switch that aligns more closely with their typing preferences, whether they prioritize a lighter touch to reduce fatigue during long sessions or a stronger feedback to enhance their typing experience.
Travel distance
The HMX Xinhai linear switch features a travel distance of 3.4 mm, while the TTC Yunhai linear switch has a slightly longer travel distance of 3.6 mm. This means that the Xinhai is the shorter option, making it ideal for users who prefer faster response times, such as gamers. In contrast, the Yunhai, with its longer travel distance, may provide a more substantial tactile experience that some users find preferable for typing, as it feels less abrupt compared to shorter switches. If you're seeking a balance between speed and depth, understanding the differences in travel distance may help you choose the switch that best suits your preferences.

Typing experience
When comparing the sound of the HMX Xinhai and TTC Yunhai linear switches, the Xinhai is characterized by a clacky sound profile, producing sharp and snappy auditory feedback that is crisp, bright, and percussive. This clackiness contributes to an engaging typing experience and can make each keystroke feel more pronounced. In contrast, the sound profile of the Yunhai is not explicitly detailed; however, given that it's designed to provide a unique typing experience, one might expect it to lean towards a softer and calmer sound, consistent with its description of offering a deep, rounded sound profile. Ultimately, the Xinhai's sharpness and the Yunhai's unspecified sound quality suggest that they could deliver quite different auditory experiences, although it's important to note that results can also vary based on other factors such as the keyboard build and keycap choice.
When examining the feel of these two switches, the HMX Xinhai provides a notably bouncy and creamy typing experience. The bouncy feedback offers a lively and spring-like sensation, while the creamy element ensures a smooth and buttery transition between keystrokes, making for an enjoyable typing experience that feels effortless. In contrast, the TTC Yunhai is characterized by its feathery touch, requiring minimal force to actuate. This light feel reduces finger fatigue during extended typing, making it ideal for those who value comfort over long sessions. While both switches aim to enhance the typing experience, the Xinhai leans towards a rich and responsive feedback, while the Yunhai prioritizes ease and lightness.
In summary, both the HMX Xinhai and TTC Yunhai linear switches present distinct qualities tailored to different user preferences. The Xinhai stands out with its clacky sound and a combination of bouncy and creamy feel, making it suitable for those who enjoy an active and engaging typing experience. On the other hand, the Yunhai caters to typists seeking a gentle, light touch with a rounded sound profile. While the switches may have differing characteristics, choosing either will certainly result in a satisfying typing experience tailored to individual tastes.
Conclusion
To conclude, your choice between the HMX Xinhai linear switch and the TTC Yunhai linear switch will largely depend on your personal preferences for sound and tactile feel. If you lean towards a lighter bottoming out force and prefer a more vibrant typing experience, the Xinhai's clacky sound, bouncy feedback, and creamy sensation might be ideal for you. This switch excels in providing a lively, sharp sound that many find satisfying, especially in a lively office or gaming environment. On the other hand, if you prioritize a gentler and more effortless typing experience, the Yunhai linear switch stands out with its deep, rounded sound profile and feathery key press, making it a fantastic choice for lengthy typing sessions where comfort is paramount. Its smooth actuation helps reduce finger fatigue, making it well-suited for students or professionals who spend long hours at their keyboards. Ultimately, consider your typing habits and preferences in sound and feel to decide which switch aligns best with your needs in your mechanical keyboard journey.
