HMX EVA vs. Bsun Taichi
An in-depth look at the HMX EVA and the Bsun Taichi switches—which one is the best fit for you?
Overview
When it comes to choosing mechanical keyboard switches, many factors come into play, including sound, feel, and overall typing experience. The HMX EVA switch stands out with its unique resonance, inspired by the iconic colors of Evangelion Unit-01, and offers a silky smooth typing experience that many users seek for both gaming and productivity. In contrast, the Bsun Taichi switch captivates users with its enchanting high-pitched bottom-out sound, which is complemented by a long-pole stem and extended springs that promise unparalleled smoothness and stability. Both switches serve linear preferences, appealing to those who enjoy a consistent keypress without tactile feedback, yet they offer distinct auditory and tactile experiences that cater to different stylistic choices. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The HMX EVA and Bsun Taichi switches exemplify contrasting approaches to housing materials that ultimately influence their acoustic profiles. The EVA features a nylon top housing, which is known for producing a deeper, fuller sound due to its softer composition. This material absorbs sound more effectively than harder plastics, providing users with a rounder auditory experience. In contrast, the Taichi uses a polycarbonate top housing, which offers a sharper, higher-pitched sound profile. The stiffer nature of polycarbonate enhances the resonance of each keystroke, leading to a clearer and crisper sound. This fundamental difference highlights how the choice of material can dramatically alter the typist's auditory feedback.
When examining the bottom housings of these switches, both the EVA and Taichi utilize nylon, leading to similarities in the acoustic properties of this part. The nylon bottom housing contributes to the deep, rounded sound characteristic of both switches, ensuring that the tactile experience is reinforced across different types. Given that the bottom housing significantly impacts the bottom-out sound and feel, users will find a consistency in sound quality when pressing down on either switch. This shared material choice allows for a cohesive bottoming experience, despite the contrasting profiles brought by the top housings.
In summary, while the HMX EVA and Bsun Taichi switches display differing top housing materials—nylon versus polycarbonate—both switches share the benefits of nylon in their bottom housings. This combination of materials results in a unique sound profile for each switch, allowing typists to experience a rich blend of auditory feedback. While those seeking a fuller sound may prefer the EVA, others who favor a sharper acoustic profile might gravitate toward the Taichi. Nevertheless, the similarity in bottom housing material ensures that both switches provide a satisfying, deep sound sensation, creating a well-rounded typing experience regardless of the choice of top housing.
Weight
When comparing the HMX EVA linear switch to the Bsun Taichi linear switch, the actuation and bottom out forces present some interesting differences. The EVA switch features a light actuation force of 42 grams and a bottom out force of 48 grams, providing a gentle typing experience that is ideal for extended use, such as during work or long gaming sessions. In contrast, the Taichi switch has a slightly lighter actuation force of 40 grams, although its bottom out force is unknown. This means that while the Taichi may offer a lighter feel in terms of actuation, without a specified bottom out force, it's difficult to ascertain how substantial the overall typing experience might be. In terms of weight, the EVA is heavier, making it potentially less suited for extended typing sessions for those who prefer lighter switches. Ultimately, the choice between these switches may hinge on personal preference regarding actuation force and the tactile feedback of bottoming out, with the EVA delivering a more defined experience due to its known bottom out force.
Travel distance
The HMX EVA linear switch and the Bsun Taichi linear switch both exhibit the same travel distance of 3.6 mm. This similarity means that users can expect a comparable feel when pressing down on the keys of devices utilizing either switch, resulting in a consistent typing experience where the travel distance does not impede the performance. Since both switches have equal travel distances, they should deliver similar results in terms of key actuation and overall feedback during use.

Typing experience
In terms of sound, the HMX EVA linear switch is characterized by a resonant sound signature that adds a unique auditory element to each keystroke, while the Bsun Taichi linear switch is known for its enchanting high-pitched bottom-out sound, thanks to its long-pole stem and extended springs. Both switches offer distinct acoustic experiences, but the EVA's sound may provide a deeper, more resonant tone, while the Taichi's higher pitch contributes to a brighter overall sound. It's important to note that the actual sound profile can vary significantly based on the keyboard's construction and the keycap material used, which can affect how these switches perform in practice.
When it comes to feel, the HMX EVA is praised for its silky smooth typing experience that ensures fluid and seamless keystrokes, making it a popular choice for those who prioritize a pleasant typing sensation. Conversely, the Bsun Taichi linear switch boasts unparalleled smoothness and stability facilitated by its long-pole stem and structural design. Both switches are engineered to deliver a smooth typing experience, contributing to a comfortable and enjoyable interaction with the keyboard. Overall, users can expect a similar level of quality and satisfaction in their typing experience from both switches.
In conclusion, while the HMX EVA linear switch offers a resonant sound and a silky smooth feel, the Bsun Taichi linear switch presents a high-pitched audible feedback and a focus on smoothness and stability. Both switches provide enjoyable sound and tactile experiences, though they may cater to slightly different auditory preferences. Ultimately, the choice between these switches could come down to individual taste, particularly regarding sound characteristics, but either switch promises similar levels of smoothness and comfort.
Conclusion
To conclude, choosing between the HMX EVA linear switch and the Bsun Taichi linear switch largely depends on your personal preferences for tactile experience and sound profile. If you prefer a lighter bottom-out force with a smooth typing feel and a unique resonant sound signature inspired by the iconic colors of Evangelion, then the HMX EVA would be an excellent choice for you. Its 48-gram actuation provides a softer touch, making it ideal for long typing sessions or casual gaming where comfort is paramount. On the other hand, if you're seeking a more enchanting auditory experience with a high-pitched bottom-out sound and a smooth feel, the Bsun Taichi linear switch may be the better option. Its long-pole stem and extended springs deliver unrivaled stability and smoothness, making it suitable for competitive gaming where responsiveness is key. Ultimately, your decision should reflect your preferences for sound and feel, as each switch offers a distinct experience tailored to different typing styles and habits.
