Gazzew U4T vs. SP-Star Yanyu
An in-depth look at the Gazzew U4T and the SP-Star Yanyu switches—which one is the best fit for you?
Overview
If you're in the market for a mechanical keyboard switch that offers a satisfying tactile feedback and a deep, bassy sound profile, the Gazzew U4T may be the perfect fit for you. Known for its harmonious fusion of thockiness and sharp tactility, the U4Ts provide a truly immersive typing experience. On the other hand, if you prefer a more delicate typing experience or find yourself typing for long periods of time, the SP-Star Yanyu switch should be on your radar. With its material blend that gives it a crisp sound profile, the Yanyu offers a subtle yet satisfying typing experience. However, let's dive in a bit deeper beyond these generalities so you can best decide on the best switch for you.

Housing materials
The Gazzew U4T and the SP-Star Yanyu differ in terms of their housing materials. The U4T features a proprietary Gazzew blend top and bottom housing, sometimes known as "boba plastic," which offers a rich and deep sound profile thanks to its softness. In contrast, the Yanyu utilizes a Polymer nylon and UHMWPE blend top and bottom housing. This blend is highly unique, providing a pleasant sound profile that leans towards the brighter side without being overly sharp. While both switches aim to deliver a satisfying typing experience, their housing materials contribute distinct characteristics to the overall feel and sound.
When it comes to the Gazzew U4T, the softness of the proprietary plastic blend in both the top and bottom housing plays a significant role. This softness translates into a rich and deep sound profile, providing a more mellow and immersive typing experience. In comparison, the Yanyu's housing materials add their own twist. The Polymer nylon and UHMWPE blend result in a slightly brighter sound, introducing a crispness to the keystrokes without sacrificing overall pleasantness. Thus, although the two switches offer different sound profiles, they strive to deliver an enjoyable typing experience through their respective housing materials.
While the U4T and Yanyu vary in their housing materials, the impact of these materials on typing can be observed in similarities as well. When it comes to the bottom housing, both switches benefit from the qualities brought by their respective materials. The Gazzew U4T's soft bottom housing contributes to a rich and deep sound upon bottoming out a key, while the Yanyu's Polymer nylon and UHMWPE blend offers a unique sound profile that strikes a balance between sharpness and pleasantness. On the other hand, when you release a key, the impact of the top housing becomes more apparent. The U4T's proprietary blend contributes to a distinct sound when a key is released, while the Yanyu's blend adds its own touch of brightness. Hence, the top housing materials bring their own unique influences to the sound profile of each switch.
In summary, the Gazzew U4T and the SP-Star Yanyu feature different housing materials that contribute to their sound profiles. The U4T's proprietary Gazzew blend offers a softness that results in a rich and deep sound, while the Yanyu's Polymer nylon and UHMWPE blend adds a pleasant brightness. However, both switches share similarities in their bottom housing characteristics, providing a satisfying bottom-out sound. Additionally, the impact of the top housing becomes more noticeable when releasing a key, with each switch possessing its own distinct sound. Ultimately, both switches aim to enhance the typing experience through their unique housing materials and resulting sound profiles.
Weight
When comparing the actuation force and bottom out force of the Gazzew U4T tactile switch and the SP-Star Yanyu linear switch, there are some notable differences. The actuation force of both switches is listed as unavailable, meaning that we do not have specific numerical values to compare. However, it can be assumed that the actuation forces are relatively similar since they are not mentioned as being significantly different.
In terms of the bottom out force, we can see that the U4T has a higher force requirement with 62 grams, which can be considered medium in comparison. On the other hand, the Yanyu has a lighter bottom out force of 43 grams, classifying it as a light switch.
Weight is an important factor to consider when choosing a switch, as it can greatly impact typing comfort and endurance. Those who prefer a lighter weight switch may opt for the Yanyu, as it requires less force to bottom out and allows for extended typing sessions without excessive fatigue. This makes it a suitable choice for situations like using a keyboard at work or engaging in long gaming sessions.
On the contrary, individuals who desire a more solid and substantial typing experience may lean towards the U4T. With its higher bottom out force, it offers a stronger push feel, providing a more substantial tactile feedback. This can be favorable for those who prefer a more assertive typing experience.
Although the specific actuation forces are unknown, it can be assumed that both switches provide similar results in terms of actuation, as they are not mentioned to be significantly different. Ultimately, the choice between the two switches will depend on personal preference and the desired typing experience – whether it be a lighter and more effortless keystroke with the Yanyu or a more robust and firm feel with the U4T.
Travel distance
The travel distance of the Gazzew U4T tactile switch and the SP-Star Yanyu linear switch is the same, with both switches having a travel distance of 4 mm. This means that when you press down on a key with either switch, you will experience the same distance of movement. Therefore, whether you choose the U4T or the Yanyu, you can expect similar tactile feedback and key travel distance.

Typing experience
The Gazzew U4T tactile switch is best known for its harmonious fusion of thockiness and sharp tactility, resulting in a satisfying auditory and tactile experience. The switch produces a bassy 'thock' sound profile, characterized by a deeper and richer sound during key presses. This is coupled with an assertive tactile feedback, with a strong and crisp tactile bump that can be distinctly felt with each keypress. The sound and feel of the U4T switches make them ideal for those who enjoy a deeper, more pronounced typing experience.
On the other hand, the SP-Star Yanyu linear switch offers a more delicate typing experience, making it suitable for prolonged typing sessions. The Yanyu switch has a material blend that provides a crisp sound profile, although it is described as neutral in terms of sound. The switch falls into a safe, middle-ground zone, making it approachable for most users. Its mild and feathery qualities make it exceptionally light to press and reduce finger fatigue, allowing for comfortable extended typing sessions.
Overall, the Gazzew U4T tactile switch and the SP-Star Yanyu linear switch offer different subjective qualities in terms of sound and feel. The U4T provides a bassy 'thock' sound profile and sharp tactile feedback, while the Yanyu offers a more delicate typing experience with a crisp sound. The U4T is best suited for users who prefer a deeper, richer sound and a prominent tactile feel, whereas the Yanyu is suitable for those looking for a gentler typing experience or for extended typing sessions. Although they offer different qualities, both switches are capable of providing a satisfying and enjoyable typing experience. The choice between the two ultimately depends on the user's personal preferences and typing style.
Conclusion
In closing, if you are someone who prioritizes a deep and satisfying sound profile accompanied by a strong and crisp tactile feedback, the Gazzew U4T switches would be an excellent choice for you. With its medium bottom out force of 62 grams, these switches offer a distinct thockiness and sharp tactility that can provide both auditory and tactile satisfaction. Additionally, if you are someone who prefers a switch with a more assertive tactile feel, the U4T's sharp tactile bump will give you that intense feedback with each and every keystroke.
On the other hand, if you are seeking a more delicate and gentle typing experience, especially for long periods of time, the SP-Star Yanyu switches would be more suitable for you.
