Kailh NovelKeys Blueberry vs. Gazzew U4Tx

Overview

When it comes to choosing the perfect mechanical keyboard switch, two popular options to consider are the Kailh NovelKeys Blueberry and the Gazzew U4Tx. The Blueberry switches are renowned for their sharp tactile bump, which appeals to those who prefer a more pronounced and satisfying typing feel. These switches have a lower-than-average sound frequency, resulting in a deeper but not overly "thocky" sound. On the other hand, the U4Tx switches offer the best of both worlds, combining the deep and resonant "thock" when bottoming out with the whisper-quiet stealth when topping out. They provide a sharp and satisfying tactile bump, ensuring a luxurious typing experience that is both acoustically pleasing and tactile. However, let's dive in a bit deeper beyond these generalities so you can make the best decision according to your preferences.

Housing materials

The Kailh NovelKeys Blueberry and the Gazzew U4Tx feature different housing materials that contribute to their unique sound profiles. The NovelKeys Blueberry utilizes POM (polyoxymethylene) for both its top and bottom housing. This material creates a pleasing and distinct sound that is deeper and relatively more muted. On the other hand, the Gazzew U4Tx employs a proprietary plastic blend referred to as "boba plastic" for its top and bottom housing. This blend delivers a rich and deep sound profile due to its softness.

While the NovelKeys Blueberry and the Gazzew U4Tx have different housing materials, they both result in a deep and rich sound profile. The POM top housing of the Blueberry and the "boba plastic" top housing of the U4Tx contribute to the overall sound when you release a key. The softness of the Gazzew blend and the characteristics of POM create a satisfying sound experience that is distinct to each switch.

The bottom housing, on the other hand, has a greater impact on the bottom-out sound and feel of the switch. The POM bottom housing of the Blueberry and the "boba plastic" bottom housing of the U4Tx provide a different tactile experience when pressing down on the keys. The material properties of POM and the Gazzew blend create unique sensations upon actuation, allowing users to feel the qualities of each switch in their typing experience.

In summary, although the Kailh NovelKeys Blueberry and Gazzew U4Tx differ in their housing materials, they both offer comparable results in terms of sound profiles. The POM top and bottom housing of the Blueberry and the "boba plastic" top and bottom housing of the U4Tx contribute to the overall sound experience, with slight variations in feel and tactility. Ultimately, both switches deliver a distinct and pleasing typing experience that can be tailored to individual preferences.

Weight

Comparing the actuation force and bottom out force of the Kailh NovelKeys Blueberry tactile switch and the Gazzew U4Tx tactile switch reveals some key differences. The NovelKeys Blueberry has an actuation force of 55 grams, while the actuation force of the U4Tx is currently unavailable. In terms of the bottom out force, the Blueberry requires 80 grams, whereas the U4Tx requires 65 grams. This makes the Blueberry switch heavier overall in both actuation and bottom out forces. However, for those who prefer a lighter typing experience, the U4Tx may be a more suitable option as its actuation force is likely to be lighter than the Blueberry. On the other hand, if a more substantial typing feel is desired, the heavier actuation and bottom out forces of the Blueberry may be more appealing. Ultimately, both switches offer unique characteristics to cater to the preferences of different typists.

Travel distance

The Kailh NovelKeys Blueberry tactile switch has a travel distance of 4 mm, which is considered the more traditional option. On the other hand, the Gazzew U4Tx tactile switch has a slightly shorter travel distance of 3.6 mm. This makes the U4Tx the shorter option compared to the NovelKeys Blueberry. Shorter travel distances are often favored by gamers who prioritize faster response times. If you prefer a more responsive typing experience, the U4Tx would be a suitable choice. However, some individuals may find shorter travel distances to feel too abrupt. For those who prefer a deeper typing sensation, the NovelKeys Blueberry and its longer travel distance would be the recommended option. In conclusion, while both switches offer tactile feedback, the NovelKeys Blueberry has a longer travel distance compared to the Gazzew U4Tx.
