Bsun Chiikawa - 28g vs. HMX EVA
An in-depth look at the Bsun Chiikawa - 28g and the HMX EVA switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, the Bsun Chiikawa - 28g and the HMX EVA are two notable options, each exhibiting unique characteristics that cater to different typing preferences. The Chiikawa - 28g is celebrated for its light 28g actuation force, delivering a highly responsive typing experience accompanied by a bright and crisp high-pitched sound profile. This makes it an excellent choice for those who favor a nimble and lively feel, perfect for fast typists or gamers looking for quick keystrokes. In contrast, the HMX EVA, inspired by the iconic colors of Evangelion Unit-01, offers a resonant sound signature that complements a silky smooth typing feel. This switch is ideal for users who appreciate a more immersive auditory experience alongside a comfortable, fluid action. While both switches share the linear attribute, highlighting the absence of tactile bumps, their distinct sound profiles and actuation forces cater to varied preferences. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The Bsun Chiikawa - 28g and the HMX EVA switches utilize different materials for their top housings, which fundamentally affects their acoustic properties. The Chiikawa - 28g features a polycarbonate top housing, known for its rigidity and translucence. This material produces a sharper and crisper sound profile, making it particularly suitable for configurations that include RGB lighting, as its transparency enhances the light's diffusion. In contrast, the HMX EVA is equipped with a nylon top housing, which is softer and absorbs sound more effectively. This results in a deeper and fuller acoustic experience. Therefore, when it comes to the sound generated during keypresses, the Chiikawa - 28g may provide a more vibrant sound suitable for gamers or users seeking precision, while the HMX EVA appeals to those preferring a warmer and more muted auditory feedback.
Both the Chiikawa - 28g and the HMX EVA share nylon for their bottom housings, which is a classic choice in switch design. Nylon is known for its ability to dampen sound, contributing to the overall auditory profile of the switch by providing a rounder and softer bottom-out sound. This shared material means that, despite the different top housing materials, both switches will still exhibit a similar sound profile when bottoming out, as they leverage the properties of nylon. Therefore, while the Chiikawa - 28g's sharper top adds vibrancy during the release phase, the deeper qualities of nylon in both bottom housings ensure that the bottom-out feel and auditory experience remain comparable.
In summary, the key contrast between the Bsun Chiikawa - 28g and the HMX EVA lies in their top housing materials: polycarbonate vs. nylon. The former supports a more resonant and treble-oriented sound profile, while the latter yields a warmer tone with dulled resonance. However, the incorporation of nylon in both bottom housings effectively bridges the acoustic differences between the two switches, allowing users to enjoy a satisfying bottom-out sound that is consistent across both options. Therefore, despite the varying top housings, users can expect a harmonious tactile feedback experience when pressing down on either switch, while the auditory properties can differ significantly based on the top materials used.
Weight
When comparing the Bsun Chiikawa - 28g linear switch with the HMX EVA linear switch, there are notable differences in both actuation force and bottom out force. The Chiikawa switch features a light actuation force of 28 grams and a bottom out force of 34 grams, making it ideal for those who prefer a softer touch, especially beneficial for extended typing sessions or gaming marathons. In contrast, the HMX EVA switch has a significantly heavier actuation force of 42 grams and a bottom out force of 48 grams, appealing to users who enjoy a more substantial feel when typing. This difference in weight indicates that the Chiikawa switch is the lighter option, while the EVA switch is heavier. Consequently, individuals seeking a gentler keypress will find the Chiikawa switch more suitable, whereas those desiring a firmer keystroke experience should opt for the EVA switch.
Travel distance
Both the Bsun Chiikawa - 28g linear switch and the HMX EVA linear switch have an identical travel distance of 3.6 mm, meaning that when pressing down on a key with either switch, the distance you feel is the same. This matched travel distance indicates that users can expect a similar tactile experience when using these switches, providing consistent feedback and performance during typing or gaming. Since both switches feature this equal travel distance, they are likely to deliver comparable results in terms of actuation and overall feel.

Typing experience
In terms of sound, the Bsun Chiikawa - 28g linear switch is known for its bright sound profile, producing a crisp, high-pitched sound that resonates with a lively character. This quality, combined with its very light actuation force, makes the typing experience feel responsive and engaging. On the other hand, the HMX EVA linear switch features a more resonant sound signature that enhances its auditory appeal. While the EVA's sound may not be as high-pitched as the Chiikawa’s, it is designed to provide a satisfying acoustical experience that contributes to a more immersive typing environment. Both switches will deliver an enjoyable auditory experience, though the Chiikawa may have a brighter edge while the EVA's overall character emphasizes resonance.
When it comes to feel, the Chiikawa - 28g offers an incredibly light and responsive tactile threshold, allowing for quick and effortless keystrokes that appeal to typists who prefer a featherlight touch. Its design encourages agile typing without any noticeable resistance, making it ideal for those who prioritize speed and precision. Conversely, the HMX EVA linear switch is celebrated for its silky smooth typing experience, promoting an exceptionally fluid and seamless transition between keystrokes. While the Chiikawa emphasizes light actuation for rapid input, the EVA maintains a luxurious feel that ensures comfort during extended typing sessions, catering to users who appreciate smoothness in their keypresses. Although the Chiikawa and EVA may have varying characteristics, both are designed to enhance the typing experience in their own unique ways.
In conclusion, both the Bsun Chiikawa - 28g linear switch and the HMX EVA linear switch offer distinct yet appealing auditory and tactile qualities. The Chiikawa stands out with its bright sound and lightweight feel, making it ideal for those seeking a responsive typing experience. In contrast, the EVA captivates with its resonant sound and silky smoothness, appealing to users who prefer a more luxurious keypress. While their characteristics differ, both switches will provide satisfying results based on their unique designs, allowing newcomers to explore different preferences and find a switch that best fits their typing style.
Conclusion
To conclude, your choice between the Bsun Chiikawa - 28g linear switch and the HMX EVA linear switch should be guided by your personal preferences in sound, feel, and actuation force. If you're looking for a switch with a super light actuation force that allows for quick and effortless typing, the Chiikawa - 28g is an excellent choice. Its bright sound profile and crisp response make it particularly appealing for users who enjoy fast-paced typing or gaming, and it can be a delightful experience, especially for those who appreciate a higher pitch in their keystrokes. Conversely, if you prefer a bit more weight in your switches, the HMX EVA might be better suited for you. With a bottom out force of 48 grams and a silky smooth feel, it offers a more substantial typing experience while still maintaining a resonant sound that could remind you of its inspiring design influences. Ultimately, your decision should reflect not just the specifications but also how each switch feels during everyday use, ensuring you choose the perfect switch that aligns with your typing style and auditory preferences.
