Gazzew U4T vs. HMX Xinhai
An in-depth look at the Gazzew U4T and the HMX Xinhai switches—which one is the best fit for you?
Overview
When it comes to the world of mechanical keyboards, switch choice can greatly influence your typing experience, and two popular options are the Gazzew U4T and the HMX Xinhai. The Gazzew U4T is celebrated for its distinct 'thocky' sound and sharp tactile feedback, providing an immersive experience that offers a satisfying auditory sensation with every keystroke. Its bassy characteristics make it a favorite among typists who appreciate a profound tactile connection while typing. In contrast, the HMX Xinhai is a linear switch that features a unique PA12 top housing and a POM stem, delivering a softer acoustic profile and a crisp, higher-pitched resonance. This switch is ideal for those who prefer a smooth, uninterrupted keystroke with a bouncy and creamy feel, perfect for rapid typing or gaming without the distraction of tactile bumps. With these key differences—sound and feel—both switches cater to different preferences and needs, making them suitable for various applications. However, let's dive in a bit deeper beyond generalities so you can best decide on the right switch for you.

Housing materials
When comparing the housing materials of the Gazzew U4T and the HMX Xinhai, there are notable similarities and differences that affect their overall auditory performance and tactile experience. Both the U4T and Xinhai leverage softer plastic materials—specifically, the U4T employs a proprietary blend known as "boba plastic," while the Xinhai utilizes traditional nylon. These materials contribute to a deeper and fuller sound profile when typing, as their softness allows for greater sound absorption compared to harder plastics. Thus, both switches promote a rich auditory experience, making them suitable for users seeking a satisfying acoustic response.
Delving into the specific impacts of the housings, the Gazzew blend in the U4T's top and bottom housings creates a uniform softness that enhances the switch's overall sound quality. Similarly, the nylon used in the Xinhai's housings also focuses on sound dampening, fostering a soundscape characterized by its duller and rounder tone. Although the materials differ in composition, the result is fundamentally analogous; both switches are designed to minimize high-pitched noises and harsh sounds, resulting in a more pleasant typing environment. This convergence in acoustic characteristics illustrates how different materials can yield comparable performances when effectively designed.
However, the impact of each housing material is not entirely equal and can influence how users perceive the switches during actual usage. While both the U4T and Xinhai utilize softer materials to enhance sound quality, the properties of the proprietary Gazzew blend can impart a unique tactile sensation that may differ slightly from that of nylon. With the U4T, the qualities of the top housing can enhance the feel upon releasing a key, whereas the nylon construction in the Xinhai may lend a slightly different tactile feedback. Ultimately, while both types of housing offer advantages in sound and feel, the nuanced differences in material composition could lead to varied typing experiences, though the overall rich sound profile remains a unifying feature of both switches.
Weight
When comparing the Gazzew U4T tactile switch and the HMX Xinhai linear switch, we see a notable difference in both actuation force and bottom out force. The U4T's actuation force is unspecified, but it has a bottom out force of 65 grams, categorizing it as medium-heavy. In contrast, the Xinhai switch features a light actuation force of 37 grams and a bottom out force of 45 grams. This distinction means that the U4T provides a substantial physical resistance that some users might prefer for a more engaging typing experience, while the Xinhai's lighter feel is more suitable for extended typing sessions and gaming, as it requires less effort to actuate and bottom out. Therefore, if you're looking for a lighter switch for prolonged use, the Xinhai would be the better choice, whereas those who enjoy a heavier touch might lean towards the U4T. Overall, the response of these switches can be quite different, aligning with the distinct preferences users may have regarding typing feel and effort.
Travel distance
The Gazzew U4T tactile switch features a travel distance of 4 mm, while the HMX Xinhai linear switch has a shorter travel distance of 3.4 mm. This means that the U4T offers a more pronounced depth when pressed, which can be preferable for those who enjoy a more tactile experience while typing or gaming. In contrast, the Xinhai's shorter 3.4 mm travel distance caters to users who prioritize responsiveness and quicker actuation, often favored by gamers looking for faster response times. Ultimately, if you prefer a hearty depth and a more noticeable travel experience, the Gazzew U4T would be the better choice, while the HMX Xinhai would suit those who appreciate a more rapid and shallow keystroke.

Typing experience
When it comes to sound, the Gazzew U4T tactile switch delivers a deep and rich auditory experience characterized by its bassy and thocky tones. Each keystroke provides a resonant thock that contributes to an overall satisfying acoustic profile, reminiscent of a deep "thud" or a soft "knock." In contrast, the HMX Xinhai linear switch showcases a clacky sound, producing a sharp and snappy auditory feedback with a bright and crisp resonance. This is often associated with a more percussive feel as you type, leading to a distinct sound profile that leans towards higher frequencies. Overall, if you prefer a richer and more profound sound, the U4T would be more to your liking, while the Xinhai offers a brighter, crisper acoustic experience.
In terms of feel, the U4T excels with its sharp tactile feedback, providing a highly pronounced tactile bump that is accessible and easy to discern with every keystroke. This makes for a more engaging typing experience, especially for those who appreciate a strong tactile sensation. The HMX Xinhai switch, on the other hand, is designed to offer a bouncy and creamy feel, which is characterized by a spring-like responsiveness that encourages a lively typing experience. Its creamy nature contributes to a buttery smoothness, allowing for glidable keystrokes that can feel incredibly satisfying. The U4T caters to those who favor clear tactile feedback, whereas the Xinhai appeals to users looking for a more fluid and comfortable typing experience.
Ultimately, both switches have their unique auditory and tactile qualities, making them suited for different preferences in the mechanical keyboard community. The U4T is ideal for users who enjoy a solid tactile response accompanied by a bassy sound, creating a satisfying and engaging typing experience. Conversely, the HMX Xinhai linear switch caters to those who prefer a fluid, creamy typing sensation coupled with brighter and sharper acoustics. Depending on your typing style, you can choose between the assertive feedback of the U4T or the smooth performance of the Xinhai, each providing an enjoyable experience in its own right.
Conclusion
To conclude, when choosing between the Gazzew U4T tactile switch and the HMX Xinhai linear switch, your decision ultimately depends on your specific typing style and preferences. If you enjoy a more substantial typing experience with satisfying auditory feedback, the U4T is an excellent choice, thanks to its heavier bottom-out force of 65 grams, rich thocky sound, and sharp tactile feedback. This makes it ideal for users who prefer a dynamic typing environment that provides both tactile and auditory satisfaction, enhancing focus and engagement during extended typing sessions. On the other hand, if you favor a lighter, more fluid typing experience—perhaps for fast-paced gaming or extensive typing without fatigue—the Xinhai's lighter 45 grams bottom-out force, combined with its bouncy and creamy feel, will likely suit you better. The Xinhai's crisp clacky sound profile adds a level of excitement to each keystroke, making it perfect for those who appreciate a lively acoustic signature. Ultimately, weigh your preferences for sound, feel, and actuation force to determine which switch aligns best with your personal style.
