Kailh Plum vs. Gazzew U4Tx
An in-depth look at the Kailh Plum and the Gazzew U4Tx switches—which one is the best fit for you?
Overview
When it comes to choosing a mechanical keyboard switch, two options that stand out are the Kailh Plum and the Gazzew U4Tx, both of which are tactile switches. The Plum is known for its unique combination of weightiness and a moderate tactile bump. Unlike many other tactile switches, the Plum's tactility and weight are not directly correlated. Additionally, it offers a neutral and enjoyable sound profile. On the other hand, the Gazzew U4Tx switches marry the best of both worlds, providing a refined sound profile that combines the deep, resonant "thock" when bottoming out with the whisper-quiet stealth when topping out. These switches offer a sharp, satisfying tactile bump for a luxurious typing experience that is both acoustically pleasing and tactile. However, let's dive in a bit deeper beyond these generalities so that you can make the best choice based on your preferences.

Housing materials
The housing materials of the Kailh Plum and the Gazzew U4Tx differ in terms of the top housing. The Plum utilizes a polycarbonate top housing, which provides a sharper, higher-pitched, and crisper sound profile. This is due to polycarbonate's rigidity, resulting in a clear and resonant sound. Additionally, the translucent nature of polycarbonate makes it ideal for switches with RGB lighting. On the other hand, the U4Tx's proprietary Gazzew blend top housing, often referred to as "boba plastic," offers a rich and deep sound profile because of its softness. This unique plastic blend delivers a more mellow and soothing auditory experience.
In terms of the bottom housing, both switches utilize different materials. The Plum relies on a nylon bottom housing, a classic material known for its ability to elicit a deeper and fuller sound profile. Nylon absorbs more sound compared to harder plastics, resulting in a duller and rounder sound. Similarly, the U4Tx incorporates Gazzew's proprietary blend for its bottom housing, which provides a rich and deep sound profile due to its softness. This material, also known as "boba plastic," contributes to the overall auditory experience by offering a softer and more satisfying bottom-out sound.
It is important to note that the top and bottom housings of both switches play different roles in the overall sound and feel of the switch. The bottom housing predominantly affects the bottom-out sound and feel when the key is pressed, while the top housing has a greater impact on the sound when the key is released. Despite their differences, the contrasting housing materials of the Kailh Plum and the Gazzew U4Tx offer their own unique sound profiles, with the Plum emphasizing clarity and resonance through its polycarbonate top housing and nylon bottom housing, and the U4Tx emphasizing richness and depth with its "boba plastic" blend for both the top and bottom housings.
Weight
When comparing the actuation force and bottom out force of the Kailh Plum tactile switch and the Gazzew U4Tx tactile switch, it is important to note that the specific actuation forces for both switches are unavailable. However, in terms of bottom out force, the Plum is slightly heavier with a measurement of 70 grams, which falls into the medium-heavy category. On the other hand, the U4Tx has a slightly lighter bottom out force of 65 grams, also categorized as medium-heavy.
Weight becomes a significant factor to consider when choosing between these switches. Those who prefer a lighter typing experience may lean towards the U4Tx, as it allows for longer periods of typing without causing fatigue. This would be ideal for individuals using the keyboard for extended periods, whether for work or gaming purposes.
However, for those seeking a more substantial and forceful push feel, the Plum may be the preferred option. The slightly heavier bottom out force of 70 grams can provide a more satisfying tactile feedback during typing, resulting in a more substantial typing experience.
Although the actuation force for both switches is unknown, it can be assumed that they would be in a similar range considering the medium-heavy bottom out forces. Therefore, users can expect comparable results in terms of actuation force regardless of which switch they choose. Ultimately, the decision between the two switches will depend on individual preferences for typing feel and the desired weight of keystrokes.
Travel distance
The travel distance of both the Kailh Plum tactile switch and the Gazzew U4Tx tactile switch is 3.6 mm. This means that when you press down on a key with either switch, you will experience the same distance of travel. Both switches provide a consistent tactile feel during use and offer the same level of keypress feedback. Therefore, whether you choose the Plum or the U4Tx, you can expect a similar typing experience in terms of travel distance.

Typing experience
When it comes to sound, the Kailh Plum tactile switch is known for its neutral profile. This means that it has a moderate sound that is suitable for most purposes, whether you are a beginner or an advanced user and whether you are using it at home or at work. On the other hand, the Gazzew U4Tx tactile switch offers a different sound experience. It is described as bassy, providing a deeper and richer sound profile during key presses. Additionally, it is muted, which means it produces a softer and quieter sound compared to a regular switch. This combination of a deep "thock" when bottoming out and a whisper-quiet sound when topping out creates a unique and luxurious typing experience.
In terms of feel, the Kailh Plum tactile switch is described as mild and stepped. The mild characteristic offers a gentle typing experience that is approachable to most users. It doesn't have a huge tactile bump like many other tactile switches, but it still provides a satisfying feel. The stepped characteristic means that there is some pre-travel and/or post-travel, giving the switch a more mild feel compared to hypertactile switches. On the other hand, the Gazzew U4Tx tactile switch offers a sharp and intense tactile bump. With each and every keypress, users can feel a strong and crisp tactile response that is distinct and satisfying.
Taking all the available information into account, the Plum tactile switch and the Gazzew U4Tx tactile switch offer different subjective qualities. The Plum has a unique combination of a hefty feel without a huge tactile bump, along with a neutral and enjoyable sound profile. On the other hand, the U4Tx features a refined sound profile with a deep "thock" when bottoming out and a whisper-quiet topping out sound. It also provides a sharp and intense tactile bump, ensuring a luxurious typing experience. Depending on your personal preferences, you can choose either switch to achieve a different typing experience. However, it's important to note that the sound and feel of a switch can also be influenced by other factors such as the keyboard board and keycaps used.
Conclusion
In closing, when deciding between the Kailh Plum tactile switch and the Gazzew U4Tx tactile switch, it ultimately depends on your preferences for sound and feel. If you prioritize a unique switch with a moderate actuation force and a neutral sound profile, then the Plum may be the better option for you. It offers a hefty feel without a pronounced tactile bump, making it quite distinctive. On the other hand, if you value a refined sound profile that combines a deep, resonant "thock" when bottoming out with a whisper-quiet topping out sound, the U4Tx is the way to go. It provides a sharp, satisfying tactile bump, creating a luxurious typing experience. Additionally, the U4Tx is known for its sharp and intense tactile feedback, making each keypress distinct. Overall, these switches cater to different preferences, and your decision should be based on whether you prefer a unique, neutral switch or a refined, bassy switch with strong tactile feedback.
