Housing materials

The housing materials of the Kailh NovelKeys Blueberry and the Gazzew U4 switches offer distinct characteristics, while also sharing some similarities. The POM top housing of the Blueberry switch creates a unique and pleasing sound profile that is deeper and more muted. Similarly, the U4 switch features a proprietary Gazzew blend top housing, sometimes referred to as "boba plastic," which delivers a rich and deep sound profile due to its softness. In terms of sound, both switches offer a similar experience with their deep and muffled tones when pressing down on a key.

In addition to their top housings, both switches also have POM bottom housings for the Blueberry and Gazzew's proprietary blend bottom housing for the U4. The bottom housing material plays a significant role in the switch's bottom-out sound and feel. While the Blueberry switch's POM bottom housing contributes to its deeper and more muted sound profile, the Gazzew U4's proprietary blend bottom housing enhances the switch's overall richness and depth of sound. Therefore, although they differ in terms of specific materials, both switches offer a satisfying experience when pressing down keys due to their respective bottom housing qualities.

When it comes to the sound generated upon releasing a key, the top housing material becomes more influential. The POM top housing of the Blueberry switch and the proprietary Gazzew blend top housing of the U4 switch both contribute to the sound profile when a key is released. While the Blueberry switch's POM top housing produces a deeper and more muted sound, the U4 switch's "boba plastic" top housing delivers a similarly rich and deep sound. Therefore, although they may have different top housing materials, both switches offer a comparable sound experience when keys are released.

Overall, the Kailh NovelKeys Blueberry and Gazzew U4 switches showcase some similarities and differences in their housing materials. While the Blueberry switch features POM materials for both the top and bottom housings, the U4 switch utilizes a proprietary Gazzew blend for both as well. Both switches offer unique and pleasing sound profiles, characterized by deep and muted tones. The distinction between the two lies in the specific qualities each housing material brings to the switch. The bottom housing influences the bottom-out sound and feel, while the top housing plays a pivotal role in the sound when keys are released. Regardless of these differences, both switches provide a satisfying typing experience with their respective housing materials.

Weight

When comparing the actuation force and bottom out force of the Kailh NovelKeys Blueberry tactile switch and the Gazzew U4 tactile switch, we can see some key differences. The NovelKeys Blueberry has a heavier actuation force of 55 grams, while the U4 has a lighter actuation force of 43 grams. This means that the Blueberry switch requires more force to trigger a keystroke compared to the U4. Similarly, in terms of bottom out force, the Blueberry switch is heavier with 80 grams, whereas the U4 is lighter with 62 grams.

These contrasting force measurements can greatly impact the typing experience for users. Some individuals may prefer a lighter actuation force, such as that offered by the U4 switch, as it allows for longer periods of comfortable typing, making it an ideal choice for work or gaming sessions. On the other hand, those seeking a more substantial and solid typing experience might opt for the heavier actuation and bottom out forces provided by the Blueberry switch.

While the specific forces for the Kailh NovelKeys Blueberry and Gazzew U4 tactile switches differ, it is important to note that both switches cater to different preferences. If a user desires a lighter typing experience, they would likely prefer the U4 switch due to its lighter actuation and bottom out forces. Conversely, those who prefer a heavier touch would gravitate towards the Blueberry switch. Regardless of the choice, users can expect tactile feedback from both switches, albeit with different levels of force required.

Travel distance

In comparing the travel distance of the Kailh NovelKeys Blueberry tactile switch and the Gazzew U4 tactile switch, we can see that the NovelKeys Blueberry has a travel distance of 4 mm, while the Gazzew U4 has a travel distance of 3.6 mm. The 4.0 mm travel distance of the NovelKeys Blueberry is considered more traditional, offering a deeper press for those who prefer a hearty depth in their typing experience. On the other hand, the 3.6 mm travel distance of the Gazzew U4 is slightly shorter, making it a popular choice among gamers who prioritize faster response times. Those who prefer a more responsive feel may opt for the shorter travel distance of the Gazzew U4, while others who enjoy a deeper press may favor the longer travel distance of the NovelKeys Blueberry. Overall, the choice between the two switches ultimately comes down to personal preference and the desired typing experience.

Typing experience

The sound profile of the Kailh NovelKeys Blueberry switch is best described as low-pitched and resonant. The low-pitched sound provides a bass-heavy and mellow tone, while the resonant nature of the switch creates a clean and sharp auditory experience. On the other hand, the Gazzew U4 switch has a muted sound profile. This means that it produces a softer and quieter sound compared to regular mechanical switches. Both switches have a low-pitched tone, which gives them a more bass-heavy and mellow sound. However, the Blueberry switch has a slightly lower frequency, while the U4 switch is whisper quiet. It's important to note that the sound of a switch can also be influenced by other factors such as the keyboard board and keycaps used.

When it comes to feel, the NovelKeys Blueberry switch offers a snappy, buttery, textured, invigorating, and stiff typing experience. The snappy nature of the switch makes it super responsive, providing a lively typing experience. The buttery feel ensures a smooth and fluid keystroke, creating a seamless and effortless typing sensation. The switch also has a textured feature, which means there is noticeable friction when pressing the keys. Some users may prefer this subtle texture, while others might prefer a smoother and friction-free typing experience. Additionally, the switch offers an invigorating feel with pronounced feedback and a moderate to firm actuation force. It provides a snappy and reactive feel, resulting in an immersive typing sensation. Lastly, the switch has a stiff characteristic, meaning it requires a higher amount of force to actuate and bottom-out compared to other switches.

On the other hand, the Gazzew U4 switch is best described as having a sharp tactile feel. This means that it offers high feedback intensity, with a strong and crisp tactile bump that can be distinctly felt with each keypress. Unfortunately, more information about the U4's feel is not provided, so it is difficult to make a detailed comparison to the Blueberry switch in terms of feel.

In conclusion, the Kailh NovelKeys Blueberry and Gazzew U4 switches offer different subjective qualities in terms of sound and feel. The Blueberry switch has a lower-than-average sound frequency with a clean and sharp resonant sound profile. It offers a snappy, buttery, textured, invigorating, and stiff typing experience.
