HMX EVA vs. Bsun Olive

Overview

When it comes to choosing the right mechanical keyboard switch, the HMX EVA and Bsun Olive offer distinctly different experiences that cater to various preferences. The HMX EVA, inspired by the iconic colors of Evangelion Unit-01, is a linear switch known for its silky smooth typing feel and resonant sound signature, making it an excellent choice for those who prioritize a fluid and quiet keystroke. On the other hand, the Bsun Olive is a tactile switch that impresses with its medium weight and pronounced tactile feedback; its all-POM housing and long pole stem produce a deep, resonant sound and a satisfying, crisp bottom-out that appeals to users who crave a more pronounced typing sensation. Both switches provide unique auditory and tactile experiences, allowing users to tailor their keyboard feel to their liking. 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 Bsun Olive, one can observe both similarities and differences that significantly affect their sound profiles and overall typing experiences. The EVA switch features a nylon housing for both the top and bottom, which is well-regarded for its softer and more absorbent qualities. This material contributes to a deeper and fuller sound profile, creating a characteristically duller and rounder auditory experience as it effectively dampens vibrations. Conversely, the Olive employs POM material for its top and bottom housings, known for generating a unique and pleasing sound. While the Olive's sound is also on the deeper side, it possesses a more muted quality, differentiating it from the EVA's pronounced auditory depth.

What makes the comparison even more intriguing is how the differences in housing materials translate to the typing experience. Both switches aim for a rich sound profile, yet their approaches vary. The EVA's nylon offers a consistent acoustic quality throughout both housings, emphasizing the full sound experience when pressing down and releasing the keys. In contrast, the Olive's POM component splits the sound characteristics, providing a unique tonal shift between the top and bottom housing. This division allows for a different tactile sensation and sound profile during keystrokes depending on which part of the switch engages more—where the bottom housing contributes significantly to the bottom-out sound, while the top housing accentuates the release.

Ultimately, despite the differences in material composition, users of both switches can achieve similarly enjoyable sound experiences. While the EVA relies on uniform nylon properties to produce its distinct sounds, the Olive's POM materials create a nuanced variation that still results in a pleasant typing experience. The underlying principle is that each housing's contribution influences the overall sound and feel of the keypress, meaning that whether through the EVA's consistent nylon acoustics or the Olive's layered POM characteristics, both switches can provide a satisfying auditory feedback that satisfies enthusiasts’ demands for quality in keyboard switches.

Weight

When comparing the HMX EVA linear switch and the Bsun Olive tactile switch, there are notable differences in terms of actuation and bottom out forces. The EVA switch has a lighter actuation force of 42 grams and a bottom out force of 48 grams, making it suitable for longer typing sessions without fatigue. In contrast, the Olive switch features a medium-heavy actuation force of 45 grams and a significantly heavier bottom out force of 65 grams, which can provide a more substantial feel for those who prefer a firmer typing experience. Thus, the EVA switch is lighter overall, while the Olive switch is heavier. If you were to use both switches, you would experience different typing sensations due to the differences in bottom out force, with the EVA providing a softer overall feedback compared to the more pronounced resistance of the Olive.

Travel distance

When comparing the travel distances of the HMX EVA linear switch and the Bsun Olive tactile switch, there is a slight yet noteworthy difference. The EVA features a travel distance of 3.6 mm, while the Olive measures 3.4 mm. This makes the Olive the shorter of the two switches, catering to gamers or users who prefer quicker actuation for faster response times. On the other hand, the EVA, with its longer travel distance, may provide a more tactile experience that some users find satisfying, especially those who enjoy a deeper keystroke. Thus, if you value a rapid response, the Olive might be the better choice, but for a more substantial feel, the EVA would be preferable.

Typing experience

In terms of sound, the HMX EVA linear switch produces a resonant sound signature that contributes to its appeal, enabling a harmonious and pleasant auditory experience while typing. The sound signature is designed to complement the smooth typing experience the switch offers. On the other hand, the Bsun Olive tactile switch delivers a deep, resonant sound that distinguishes it from others in its category. This difference in auditory character gives users distinct auditory cues during use, enhancing the tactile experience. However, it’s important to note that the overall sound profile can be influenced by the keyboard's construction, the material of the keycaps, and other factors.

When it comes to feel, the HMX EVA switch is characterized by its silky smooth typing sensation, providing a seamless and fluid experience for the fingertips. This feature makes it ideal for those who prefer a straightforward linear feel without any tactile bumps. Conversely, the Bsun Olive switch offers a more pronounced tactile feedback thanks to its unique design and long pole stem. This results in an invigorating typing experience, with a medium-weight feel that incorporates sharp and snappy feedback, making each stroke feel responsive and alive. The tactile quality of the Olive can be described as medium tactile, giving you a substantial bump without overwhelming the user, making it a satisfying option for typing.

In conclusion, both the HMX EVA and Bsun Olive switches provide unique experiences tailored to different preferences. While the EVA switch excels with its silky smoothness and harmonious sound profile, the Olive stands out with its deep resonance and invigorating tactile feedback. Ultimately, both switches can deliver a satisfying typing experience, catering to users who may either prefer a linear feel or a more tactile engagement. Choosing between them will depend on whether you value smoothness over tactile feedback in your typing sessions, as each offers its own enjoyable characteristics.

Conclusion

To wrap up, the choice between the HMX EVA linear switch and the Bsun Olive tactile switch ultimately depends on your typing preferences and what kind of experience you seek. If you prefer a lighter touch and enjoy a smooth, uninterrupted typing feel, the HMX EVA might be the right choice for you. Its bottom-out force of 48 grams makes it ideal for extended typing sessions where fatigue can be a concern, all while delivering a uniquely resonant sound signature inspired by the iconic Evangelion aesthetic. On the other hand, if you appreciate tactile feedback during your key presses and want a switch that provides a distinct, invigorating sensation, the Bsun Olive would be a better fit. With a heavier bottom-out force of 65 grams, it offers a pronounced tactile experience that is both sharp and snappy, making it satisfying to use for both typing and gaming. Ultimately, you should choose the EVA if you’re after a smooth, light feel, and opt for the Olive if you desire a more engaging and tactile feedback with a deeper sound.
