Gazzew U4T vs. TTC Yunhai
An in-depth look at the Gazzew U4T and the TTC Yunhai switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, the choice between the Gazzew U4T and the TTC Yunhai can significantly impact your typing experience. The U4T, a tactile switch, is celebrated for its delightful balance of thockiness and an assertive tactile bump, offering a satisfying auditory 'thock' sound and a pronounced feedback that many typists crave. This makes it an excellent choice for users who enjoy a more pronounced keystroke and the accompanying sound profile that enhances their typing enjoyment. On the other hand, the TTC Yunhai, a linear switch, presents a contrasting experience with its smooth, uninterrupted keystrokes and light actuation force. Ideal for typists who favor a gentler, almost effortless feel, the Yunhai allows for rapid keystrokes without the distraction of tactile bumps or auditory noise. Each switch has its unique merits, appealing to different preferences and typing styles. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
When comparing the housing materials of the Gazzew U4T and the TTC Yunhai, both switches feature soft housing materials that contribute to their respective sound profiles. The U4T utilizes a proprietary blend referred to as "boba plastic" for both its top and bottom housings, which is known for its ability to deliver a rich and deep sound profile. Similarly, the Yunhai uses nylon for its top and bottom housing, a traditional switch material that also emphasizes a deeper and fuller sound due to its relatively soft nature. In essence, both switches share an underlying characteristic of softness in their housing materials, leading to comparable auditory experiences, such as a richer sound when typing.
Despite the similarities, the distinctive materials create slightly different sound profiles based on their specific compositions. The Gazzew U4T's proprietary blend may offer a unique tactile experience, characterized by its boba plastic, which emphasizes deep resonance and potentially adds nuances in sound that differentiate it from nylon. On the other hand, the Yunhai's nylon housing remains classic and well-regarded, likely providing a familiar yet robust sound signature. This difference in housing material can suggest that while both switches yield a rich sound, the U4T may have a slight edge in delivering a more pronounced depth due to its specialized blend.
Finally, the interaction of these housing materials with the mechanics of each switch is significant in understanding their performance. The U4T's dual "boba plastic" housings would promote a cohesive sound experience throughout the keystroke, combining effects from both the top and bottom during actuation and bottom-out. In contrast, the Yunhai's nylon housing positions it as a classic switch with sound absorption properties that create a distinct auditory experience, particularly upon releasing the key. Ultimately, both switches exhibit overlapping traits contributing to deep sound profiles, yet their unique materials introduce subtle variations in sound and tactile feedback during typing.
Weight
The Gazzew U4T tactile switch and the TTC Yunhai linear switch present a clear contrast in actuation and bottom out forces. The U4T has a bottom out force of 65 grams, which classifies it as medium-heavy, though its actuation force is unknown. In comparison, the Yunhai switch features a lighter actuation force of 42 grams and a bottom out force of 50 grams. This difference in weight may significantly affect user experience: those who type or game for extended periods may find the lighter Yunhai switch more comfortable, while users seeking a more substantial typing experience might prefer the heavier feel of the U4T. Ultimately, individuals who prefer a lighter actuation may gravitate toward the Yunhai, which gives a more responsive touch, while fans of a heavier push will likely opt for the U4T for its more robust feedback.
Travel distance
When comparing the travel distances of the Gazzew U4T tactile switch and the TTC Yunhai linear switch, it is clear that the U4T offers a longer travel distance of 4 mm, while the Yunhai features a shorter travel distance of 3.6 mm. This 0.4 mm difference may influence user preference significantly. Those who favor the Gazzew U4T may appreciate the deeper tactile feedback it provides, which some users find more satisfying for typing. On the other hand, the TTC Yunhai's shorter travel distance caters to gamers and those seeking quicker response times, making it a popular choice for fast-paced activities. Ultimately, if you prefer a more substantial feel while typing, the U4T is the better option, whereas if you’re inclined towards a snappier experience, the Yunhai would likely suit your needs better.

Typing experience
When it comes to sound, the Gazzew U4T switch stands out with its rich and deep thocky profile. This switch produces a bassy resonance that gives each keystroke a satisfying auditory experience, akin to a soft "knock" or a deep thud. This character enhances the overall typing performance by adding a layer of acoustic pleasure. In contrast, the TTC Yunhai switch offers a unique auditory experience, although the specific sound characteristics are not detailed. Regardless, the gentle and rounded nature of the Yunhai suggests a more subdued and less impactful sound compared to the robust thock of the U4T. The overall sound experience can also vary based on the keyboard build, keycap material, and other factors that influence acoustics.
In terms of feel, the U4T excels with its sharp tactile feedback. The pronounced bump provides a clear and distinct sensation with each keypress, making the typing experience highly engaging for those who appreciate tactile switches. The tactile feedback is intense and precise, ensuring that typists can feel each actuation clearly. Meanwhile, details about the feel of the TTC Yunhai switch are not provided, leaving a gap in comparison. However, the Yunhai is known for its incredibly light actuation force, which may contribute to a much different typing sensation—likely softer and more forgiving, further emphasizing ease of use rather than the tactile intensity of the U4T.
In summary, the Gazzew U4T tactile switch offers a pronounced thocky sound and a sharp, satisfying tactile feel, making it ideal for those who enjoy a more impactful typing experience. The TTC Yunhai switch provides a contrasting approach with its gentle actuation and rounded sound profile, although its tactile feel remains largely unknown. Ultimately, choosing between these switches will depend on personal preferences regarding sound and tactile feedback, with the U4T catering to those who favor a strong, immersive experience, while the Yunhai serves those seeking a softer, lighter touch. If you're looking for a unique experience, trying both could give you insight into which qualities you prefer.
Conclusion
To conclude, choosing between the Gazzew U4T tactile switch and the TTC Yunhai linear switch ultimately depends on your typing preferences and intended use. If you appreciate a medium-heavy tactile experience with a noticeable bump and a satisfying thock sound, the U4T would be the better choice for you. Its 65-gram bottom-out force pairs perfectly with the pronounced tactile feedback, making every keystroke feel intentional and rewarding, ideal for those who enjoy a more engaging typing experience or gaming sessions where feedback is key. On the other hand, if you prefer a lighter, more effortless typing experience, the TTC Yunhai switch’s 50-gram actuation force will suit you well. Its rounded sound profile and gentle feel make it perfect for extended typing sessions, where comfort and speed are your primary considerations. Therefore, think about what aspects of typing and sound are most important to you when deciding between these two switches; your choice will greatly influence your overall satisfaction with your mechanical keyboard.
