HMX Xinhai vs. SP-Star Yanyu
An in-depth look at the HMX Xinhai and the SP-Star Yanyu switches—which one is the best fit for you?
Overview
We are excited to showcase the HMX Xinhai and the SP-Star Yanyu, two exceptional linear mechanical keyboard switches. The Xinhai switch is crafted with a unique PA12 top housing and a POM stem, resulting in a softer acoustics profile with a distinctively crisp, higher-pitched resonance. Categorized as bouncy, clacky, and creamy, the Xinhai offers a perfect blend of subtle sophistication and precise performance. On the other hand, the Yanyu switch is known for providing a more delicate typing experience, making it ideal for long typing sessions. With a material blend that produces a crisp sound profile, the Yanyu is categorized as neutral, mild, thocky, feathery, subtle, and polished. Both switches have their unique features and benefits, offering users different qualities to consider based on their preferences. However, let’s dive in a bit deeper beyond generalities so you can decide on the best switch for you.

Housing materials
The HMX Xinhai and SP-Star Yanyu both have unique housing materials that contribute to their overall sound profiles. The Xinhai features a polycarbonate top housing, which creates a sharper and crisper sound profile due to its stiffness. In comparison, the Yanyu's Polymer nylon and UHMWPE blend top housing offers a more pleasant and brighter sound. While both provide distinct sound profiles, the Xinhai's polycarbonate top housing is better suited for RGB lighting due to its translucency, providing an added aesthetic appeal.
When it comes to the bottom housing, the Xinhai utilizes nylon, which produces a deeper and fuller sound profile as a result of its softer nature. On the other hand, the Yanyu's Polymer nylon and UHMWPE blend bottom housing also offers a unique sound profile that is pleasant and brighter. Despite their differences, both bottom housings contribute to the overall typing experience by absorbing sound and creating a duller or more rounded sound. Additionally, the impact of the bottom housing is felt more when pressing down on a key, while the top housing has a greater impact on the sound when releasing the key.
Overall, while the housing materials of the HMX Xinhai and SP-Star Yanyu differ in composition and sound profiles, they both bring unique qualities to the switches. The Xinhai's polycarbonate top housing offers a sharper and crisper sound, ideal for those who prefer a more defined typing experience, especially when coupled with RGB lighting. In contrast, the Yanyu's Polymer nylon and UHMWPE blend top housing provides a more pleasant and brighter sound. Both switches demonstrate how different housing materials can impact the overall sound and feel of a typing experience, catering to a variety of preferences.
Weight
When comparing the actuation force and bottom out force of the HMX Xinhai linear switch and the SP-Star Yanyu linear switch, it is clear that the Xinhai is the lighter of the two. The Xinhai has an actuation force of 37 grams and a bottom out force of 45 grams, while the Yanyu's actuation force is unknown and bottom out force is 43 grams. Both switches can be considered light in terms of actuation force, as they require relatively low force to trigger a keystroke. However, the Xinhai requires slightly more force to bottom out compared to the Yanyu. For those who prefer a lighter typing experience, either switch would be suitable. Ultimately, the choice between the two switches may come down to personal preference for typing feel and weight.
Travel distance
The HMX Xinhai linear switch has a travel distance of 3.4 mm, making it a shorter travel distance compared to the SP-Star Yanyu linear switch, which has a travel distance of 4 mm. The Xinhai's shorter travel distance may be preferred by gamers looking for faster response times, while the Yanyu's longer travel distance may appeal to those who enjoy a more substantial keystroke feel. Both switches offer different experiences based on their travel distance, with the Xinhai providing a quicker and snappier response, while the Yanyu offers a more deliberate and pronounced keystroke. Ultimately, the choice between the two switches will depend on personal preference and the type of typing or gaming experience desired.
