HMX EVA vs. Haimu Viola Tricolor
An in-depth look at the HMX EVA and the Haimu Viola Tricolor switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboards, the choice of switch can significantly affect your typing experience, and two standout options are the HMX EVA and the Haimu Viola Tricolor. The HMX EVA, inspired by the iconic colors of Evangelion Unit-01, is a linear switch renowned for its silky smooth feel and resonant sound signature, making it an excellent choice for those who prioritize a fluid typing experience without interruption. On the other hand, the Haimu Viola Tricolor offers a tactile experience characterized by a thuddy, punchy sound profile and a pronounced tactility that provides satisfying feedback while avoiding overwhelming sensation. While both switches have their own allure—whether you prefer the seamless glide of the EVA or the engaging tactile feedback of the Viola Tricolor—your preference may ultimately depend on how you value smoothness versus tactile engagement in your daily typing tasks. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
When comparing the housing materials of the HMX EVA and the Haimu Viola Tricolor, a stark contrast emerges in their respective top housings. The EVA utilizes nylon for its top housing, a classic material known for its sound-dampening properties. Nylon, being a softer plastic, absorbs sound efficiently, resulting in a deeper and fuller sound profile when typing. In contrast, the Viola Tricolor sports a polycarbonate top housing, which is stiffer and produces a sharper, higher-pitched sound. The clarity and resonance provided by polycarbonate contribute to a more pronounced audible experience, especially when paired with RGB lighting, due to its inherent translucency. Therefore, while the EVA’s nylon top can create a rounded sound, the Viola Tricolor delivers a crisper auditory feedback, reflecting their distinctive material compositions.
Interestingly, both switches share the same bottom housing material: nylon. This similarity is significant because it allows for uniformity in the sound profile produced by both switches at the lower end. The nylon bottom housing generates that familiar deep and full sound, mitigating some of the sharper characteristics introduced by the polycarbonate top housing of the Viola Tricolor. Thus, while users may experience the contrasting sound profiles on the upward stroke of each switch due to the different top materials, the bottom-out sound and feel will resonate similarly across both switches thanks to their shared nylon bottom.
Ultimately, the combination of distinct top housings with a common bottom housing material influences the overall typing experience. With the EVA relying on nylon for both its top and bottom housing, users can expect a cohesive and rounded sound throughout their interactions. In comparison, the Haimu Viola Tricolor's construction allows for a more defined auditory experience on the keystroke but maintains the depth in sound on the bottom-out due to the nylon bottom housing. This layered approach to sound—flavored by unique materials—demonstrates how the distinctive characteristics of the top and bottom housings contribute to the overall tactile experience while still providing certain similarities in sound output.
Weight
When comparing the HMX EVA linear switch and the Haimu Viola Tricolor tactile switch, there are noticeable differences in both actuation and bottom out forces. The EVA switch features a light actuation force of 42 grams and a bottom out force of 48 grams, making it suitable for users who prefer a softer touch and longer typing sessions without fatigue. In contrast, the Viola Tricolor has a medium-heavy bottom out force of 63.5 grams, with its actuation force being unknown. This suggests that the Viola Tricolor may provide a more substantial feel during typing. Consequently, users who enjoy that heavier push experience will gravitate towards the Viola Tricolor, while those seeking a lighter option will find the EVA more appealing. Thus, the EVA is the lighter switch, favoring comfort over longer periods of use, while the Viola Tricolor caters to those who prefer a stronger tactile feedback.
Travel distance
The travel distance of the HMX EVA linear switch is 3.6 mm, while the Haimu Viola Tricolor tactile switch has a slightly longer travel distance of 3.8 mm. This difference of 0.2 mm makes the EVA the shorter option, appealing to those who prefer quicker key presses for faster response times, such as gamers. In contrast, the Viola Tricolor's longer travel distance offers a more substantial feel, which may appeal to users who appreciate a deeper keypress experience. Ultimately, the choice between these two switches hinges on personal preference: if you favor responsiveness and speed, the EVA would be the better choice; however, if you lean towards a more tactile and robust feel, the Viola Tricolor could be more to your liking.

Typing experience
When it comes to sound, the HMX EVA linear switch is renowned for its resonant sound signature, which creates a harmonious blend of acoustic depth and smoothness during typing. This results in a sound profile that is likely softer and more fluid, allowing for a less intrusive auditory experience. In contrast, the Haimu Viola Tricolor tactile switch produces a thuddy and punchy sound profile, characterized as bassy and low-pitched. The deeper tones of the Viola can provide a more engaging or pronounced auditory experience, which may appeal to those who enjoy a richer sound while typing. Ultimately, both switches offer distinctly different sound profiles that cater to varying preferences—where the EVA aims for smoothness, the Viola ensures an impactful auditory presence.
In terms of feel, the HMX EVA definitely stands out with its silky smooth typing experience, allowing for effortless keystrokes that minimize friction. This linear switch offers a seamlessly fluid actuation, making it ideal for users who prefer a gentle touch without any tactile feedback. On the other hand, the Haimu Viola Tricolor introduces an invigorating experience, offering medium tactile feedback that strikes a balance between pronounced and subtle. With its accented nature, the Viola enables a firm yet responsive typing feel, providing engaging feedback without overwhelming the user. Thus, while the EVA excels in smoothness, the Viola caters to those who relish a tactile sensation that enhances the typing experience.
In summary, both the HMX EVA linear switch and the Haimu Viola Tricolor tactile switch encapsulate unique auditory and tactile qualities that cater to differing preferences among keyboard enthusiasts. The EVA leans towards a smooth and resonant sound, creating a tranquil typing environment, while the Viola brings forth a deeper, more characterful auditory experience complemented by a satisfying tactile response. Your choice between the two will ultimately depend on whether you prioritize a seamless feel or enjoy a more pronounced reactiveness in your typing experience.
Conclusion
To conclude, your choice between the HMX EVA linear switch and the Haimu Viola Tricolor tactile switch ultimately hinges on your personal preferences and typing style. If you gravitate towards a smoother typing experience and enjoy a lighter touch, the HMX EVA, with its 48-gram bottom out force, is likely your best bet. Its unique resonant sound signature delivers a pleasant auditory experience, making it ideal for those who appreciate a more subtle yet refined sound while typing. This switch is particularly appealing for extended typing sessions or gamers who prefer quick, fluid keystrokes without the distraction of heavy tactile feedback.
Conversely, if you seek a more tactile sensation with each keystroke that adds character to your typing and gaming, the Haimu Viola Tricolor's medium-heavy bottom out force of 63.5 grams will be more suited to your needs. Its "thuddy" and "punchy" sound profile, combined with its invigorating tactical feel, allows for a satisfying feedback mechanism that isn't overly pronounced. This makes it a great choice for users who desire a more engaging typing experience that balances tactile sensation with auditory response. In summation, choose the EVA for its silky smoothness and lighter feel, while opting for the Viola Tricolor if you're looking for that extra tactile engagement and deeper sound.
