Bsun Chiikawa - 28g vs. Gazzew U4
An in-depth look at the Bsun Chiikawa - 28g and the Gazzew U4 switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, the choice often boils down to personal preference in feel and sound. On one side, the Bsun Chiikawa - 28g switch stands out as a linear option that delivers an exceptionally light actuation force of just 28 grams. This characteristic results in a highly responsive typing experience combined with a bright, high-pitched sound that many users find enjoyable and engaging. Conversely, the Gazzew U4 switch presents a tactile alternative, known for its sharp tactile bump and plush, felt-like bottom-out sensation, which can make typing feel more deliberate and satisfying. The U4 operates quietly, boasting a muted, low-pitched sound profile that many users appreciate in quieter environments. Ultimately, the choice between the Chiikawa and the U4 hinges on whether you prefer the light and fast feel of a linear switch or the tactile feedback and subtle sound design of a tactile switch. However, let's dive in a bit deeper beyond generalities so you can best decide on the right switch for you.

Housing materials
The Bsun Chiikawa - 28g and the Gazzew U4 switches exhibit notable differences in their housing materials, which distinctly influence their sound profiles. The Chiikawa - 28g features a polycarbonate top housing, recognized for its stiffer properties, which results in a sharper, higher-pitched sound. This quality is particularly beneficial for users who prioritize clarity and resonance in their switch experience. In contrast, the Gazzew U4 employs a proprietary Gazzew blend, often referred to as "boba plastic," for its top housing. This softer material leads to a warmer and richer sound profile, emphasizing deeper tones rather than the crisp highs associated with polycarbonate. Consequently, users can expect different auditory experiences when using these switches, influenced largely by the nature of the materials used in their top housings.
When examining the bottom housings, both the Chiikawa - 28g and the Gazzew U4 utilize softer plastics to achieve a more rounded and fuller sound. The Chiikawa - 28g's nylon bottom housing contributes to this depth, as nylon absorbs sound more effectively than harder alternatives, creating a more muted auditory feedback. The U4's bottom housing, made from the same proprietary Gazzew blend as its top housing, similarly enhances the sound profile by producing softness and richness. This shared characteristic in bottom housing materials suggests that, despite the differing top housings, both switches aim to achieve a satisfying sound experience rooted in deep audio feedback. Therefore, users can expect enhanced sound fullness, particularly during the bottom-out phase, resulting from the bottom housing's influence.
In summary, while the top housings of the Bsun Chiikawa - 28g and the Gazzew U4 differ in terms of material properties—polycarbonate versus a proprietary blend—the bottom housings for both switches align in their focus on achieving a richer auditory experience through softness. This complementary design helps to draw a connection between the two switches, as the top and bottom materials interact to create distinct sound profiles. Users who favor specific sound characteristics may navigate their preferences based not just on the top housing's material, but also on how the bottom housing contributes to the overall switch experience. Therefore, while the distinct upper housings create a divergence in sound profile sharpness, the similarity in the softer bottom housings ensures a foundational richness in sound that is a hallmark of both switches.
Weight
When comparing the Bsun Chiikawa - 28g linear switch and the Gazzew U4 tactile switch, significant differences in their actuation and bottom out forces are evident. The Chiikawa switch boasts a lighter actuation force of 28 grams, along with a bottom out force of 34 grams, making it suitable for users who prefer a softer touch and can type for extended periods without fatigue. In contrast, the U4 features a heavier actuation force of 45 grams and a bottom out force of 62 grams, catering to those who enjoy a more substantial and tactile typing experience. This means that the Chiikawa is the lighter option, while the U4 is on the heavier side. Users seeking a lighter and more accommodating switch for frequent use might favor the Chiikawa, whereas those who appreciate a firmer key feel should opt for the Gazzew U4. Overall, the differences in actuation and bottom out forces suggest distinct user experiences based on typing preferences and tactile feedback.
Travel distance
Both the Bsun Chiikawa - 28g linear switch and the Gazzew U4 tactile switch share the same travel distance of 3.6 mm, indicating that both switches will provide a similar experience in terms of the distance felt when pressing down on a key. Since they have identical travel distances, users can expect comparable performance and tactile feedback, making either switch a suitable choice depending on personal preference for linear versus tactile response.

This auditory quality lends itself well to a lively typing experience, making it perfect for those who enjoy the lively feedback of a light linear switch. In contrast, the Gazzew U4 tactile switch offers a more muted sound profile characterized by low-pitched tones. It minimizes the typical noise associated with mechanical keyboards, leading to a softer acoustical presence. This whisper-quiet operation makes the U4 ideal for environments where discretion is essential.
When considering how these switches feel, the Chiikawa - 28g's characteristics remain less defined in available information, but it is known for its very light actuation force, which contributes to a quick and effortless keystroke. In contrast, the Gazzew U4 features a prominent and sharp tactile bump that delivers high feedback intensity. Users will feel a distinct tactile response with every keypress, providing a satisfying typing experience. Combined with a plush bottom-out sensation, the U4 offers a cushioned feel that balances firmness with comfort, enhancing the overall typing experience.
In conclusion, both the Bsun Chiikawa - 28g and Gazzew U4 switches cater to different preferences within the mechanical keyboard community. The Chiikawa - 28g shines with its bright auditory experience and lightweight actuation, lending to a lively, responsive feel. Meanwhile, the Gazzew U4 excels in providing a muted sound profile alongside a sharp tactile feedback, paired with a plush bottom-out feel. Ultimately, the choice between these switches will depend on whether one prefers a more expressive and light switch versus a tactile, quieter option. Both types can cater to distinct typing experiences based on individual preference and typing style.
Conclusion
To conclude, your choice between the Bsun Chiikawa - 28g linear switch and the Gazzew U4 tactile switch ultimately depends on your individual typing preferences and the typing experience you seek. If you gravitate towards a lighter touch and a more vibrant acoustic feedback, the Chiikawa - 28g is the way to go. With its low actuation force and bright, high-pitched sound profile, this switch is perfect for fast-paced typing and those who appreciate a more responsive key feel, particularly suited for gaming or casual typing sessions. On the other hand, if you prefer a more pronounced tactile experience combined with a quieter environment, the Gazzew U4 is an excellent choice. Its medium bottom-out force and distinctive yet muted tactile bump offer a plush feel that many typists find satisfying, especially in office settings or when shared spaces require noise consideration. Thus, assessing your typing style, sound preferences, and desired feedback will guide you in selecting the switch that enhances your overall experience on your mechanical keyboard.
