HMX Blue Topaz vs. HMX Xinhai
An in-depth look at the HMX Blue Topaz and the HMX Xinhai switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, the HMX Blue Topaz and HMX Xinhai both offer unique features that cater to different preferences. The Blue Topaz is a linear switch that stands out for its smooth actuation and lightweight feel, resulting in a comfortable typing experience with a clacky sound signature. On the other hand, the Xinhai, also a linear switch, boasts a softer acoustics profile and a distinctively crisp, higher-pitched resonance due to its unique PA12 top housing and POM stem. While the Blue Topaz is best suited for those who prefer easy-to-press keys with a clacky sound, the Xinhai offers a bouncy and creamy typing experience with a touch of sophistication. 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 Blue Topaz and HMX Xinhai both utilize polycarbonate for their top housing, which creates a sharper, higher-pitched, and crisper sound profile. This is because polycarbonate is a relatively stiffer plastic, leading to a more clear and resonant sound. Aesthetically, the translucent nature of polycarbonate is ideal for switches with RGB lighting. However, the main difference lies in their bottom housing material. The Blue Topaz features a nylon bottom housing, which produces a deeper and fuller sound due to nylon's softer nature that absorbs more sound, creating a duller and rounder sound profile.
In comparison, the HMX Xinhai also incorporates a polycarbonate top housing for similar sound characteristics and aesthetic benefits. However, the Xinhai also utilizes a nylon bottom housing, mirroring the Blue Topaz in this aspect. Both switches offer a mix of qualities from their housing materials, with the bottom housing impacting the bottom-out sound and feel when the switch is pressed, while the top housing influences the sound when a key is released. This dual housing design allows for a more balanced and nuanced typing experience, combining the strengths of both polycarbonate and nylon in each switch.
Overall, the HMX Blue Topaz and HMX Xinhai showcase the versatility and impact of different housing materials on the sound profile and typing experience of a switch. While both switches share the benefits of polycarbonate in their top housing, their use of nylon in the bottom housing offers distinct characteristics in terms of sound depth and resonance. Whether one prefers a sharper, crisper sound or a deeper, fuller tone, these switches provide options to cater to different preferences and typing styles. Ultimately, the choice between the Blue Topaz and Xinhai may come down to personal preference in sound profile and typing feel.
Weight
The actuation force and bottom out force of the HMX Blue Topaz linear switch and the HMX Xinhai linear switch are both relatively light compared to other switches on the market. The Blue Topaz has an actuation force of 40 grams and a bottom out force of 48 grams, while the Xinhai has an actuation force of 37 grams and a bottom out force of 45 grams. Both switches provide a smooth and lightweight typing experience, making them suitable for extended typing sessions or gaming. Users who prefer a lighter touch may find either of these switches to be a good fit, as they offer a gentle actuation and bottom out force. However, individuals who prefer a more substantial typing experience may find the Blue Topaz to be slightly heavier than the Xinhai. Ultimately, the decision between the two switches will come down to personal preference in terms of actuation and bottom out force.
Travel distance
The HMX Blue Topaz linear switch has a travel distance of 3.9 mm, while the HMX Xinhai linear switch has a travel distance of 3.4 mm. In this case, the Xinhai has a shorter travel distance compared to the Blue Topaz. The shorter travel distance of the Xinhai may appeal to gamers looking for faster response times, while the longer travel distance of the Blue Topaz may be preferred by those who enjoy a more substantial keypress feeling. Both switches offer a different typing experience due to their respective travel distances, allowing users to choose based on their preference for responsiveness or key depth.

Typing experience
When it comes to sound, both the HMX Blue Topaz and HMX Xinhai linear switches are described as having a "clacky" sound profile. This means that both switches produce a sharp and snappy sound when pressed, characterized by a crisp, bright, and percussive tone. However, it's important to note that the sound of a switch is also influenced by other factors such as the keyboard's construction and the keycaps used.
In terms of feel, the Blue Topaz switch is known for its easy-to-press nature, offering gentle resistance during key presses and requiring minimal force to activate. This light actuation force makes typing effortless and comfortable, reducing finger fatigue during long typing sessions. On the other hand, the Xinhai switch is described as bouncy, providing a spring-like or elastic feedback sensation. Additionally, it offers a creamy typing experience, with a smooth and buttery feel that allows for effortless keystrokes. These qualities make the Xinhai switch perfect for users looking for a lively and tactile typing experience.
Overall, while both the HMX Blue Topaz and HMX Xinhai linear switches have similarities in terms of sound, they offer distinct differences in feel. The Blue Topaz excels in providing an easy and lightweight typing experience, while the Xinhai offers a bouncy and creamy feel that enhances tactile feedback. Depending on individual preferences and typing habits, users can choose between the two switches for a customized typing experience that suits their needs.
Conclusion
To wrap up, when deciding between the HMX Blue Topaz linear switch and the HMX Xinhai linear switch, consider the specific characteristics that align with your preferences and needs. If you are looking for a keyboard switch with a super smooth actuation and lightweight feel, perfect for effortless keystrokes and a clacky sound signature, then the Blue Topaz would be an excellent choice for you. On the other hand, if you prefer a switch with a softer acoustics profile, distinctively crisp resonance, and a blend of subtle sophistication and precise performance, the Xinhai switch would be more suitable for your typing style. Ultimately, the decision comes down to personal preference in terms of sound, feel, and overall typing experience.
