Kailh Box Royal vs. HMX EVA

An in-depth look at the Kailh Box Royal and the HMX EVA switches—which one is the best fit for you?

Overview

When it comes to mechanical keyboards, the choice of switch can drastically influence both your typing experience and overall satisfaction. The Kailh Box Royal switch stands out for its exceptionally sharp and aggressive tactile feedback, making it ideal for users who crave a pronounced sense of actuation with each keystroke. This high-pitched sound profile adds an engaging auditory element, perfect for those who appreciate a more dynamic typing environment. In contrast, the HMX EVA switch offers a smoother, linear feel that eliminates any tactile bumps, allowing for fluid keystrokes that are inspired by the vibrant aesthetics of the Evangelion Unit-01. This makes the EVA an appealing choice for gamers and typists who prefer a quiet and seamless typing experience. Both switches cater to different preferences: the Box Royal for tactile enthusiasts and the EVA for those who enjoy uninterrupted flow. However, let's dive in a bit deeper beyond generalities so you can best decide on the switch that suits you.

Housing materials

Both the Kailh Box Royal and the HMX EVA utilize nylon as their housing material for both the top and bottom sections, which leads to several similarities in the typing experience and sound profile produced by these switches. Nylon is known for its softer plastic qualities, which contribute to a deeper, fuller sound when typing. This material's ability to absorb sound results in a rounder and less harsh auditory feedback compared to switches made from harder plastics. Thus, users who opt for either the Box Royal or the HMX EVA will likely experience a tactile and auditory pleasure, characterized by a softer landing and a more muted sound when the keys are bottomed out or released.

Despite the same nylon material being used in both the Kailh Box Royal and HMX EVA switches, there could still be nuanced differences arising from design choices each manufacturer has made, potentially impacting the switches' feel or sound characteristics. For instance, if there were any variations in the switch design or if one had different spring tensions, users might notice slight differences in typing feedback or sound dynamics even though the underlying material remains the same. If the mechanical components, such as the switch stems or the orientation of housing parts, differ, it could alter how the nylon's sound-absorbing properties manifest during use.

Overall, typing on both the Kailh Box Royal and the HMX EVA would yield comparable results primarily due to the shared nylon housing. The deeper and fuller sound profiles, along with the softer tactile feedback, will be consistently present across the two models. Therefore, for users seeking that classic nylon sound and feel, both options present an appealing choice, solidifying the notion that while there may be minute differences in design, the foundational qualities brought forth by the nylon material provide a satisfying and harmonious typing experience irrespective of the switch brand.

Weight

The Kailh Box Royal tactile switch and the HMX EVA linear switch present distinct characteristics in terms of actuation and bottom out forces that cater to different user preferences. The Box Royal features an actuation force of 45 grams and a bottom out force of 70 grams, classifying it as medium-heavy. In contrast, the EVA switch has a lighter actuation force of 42 grams and a significantly lower bottom out force of 48 grams. This difference indicates that the EVA switch requires less pressure to actuate and bottom out, making it more suitable for users seeking a lighter typing experience for prolonged use, such as at work or during long gaming sessions. Conversely, the Box Royal's heavier feel may appeal to those who prefer a more substantial typing experience. Thus, while both switches have unique advantages, the Box Royal is the heavier option, while the EVA is lighter, leading to different tactile and ergonomic benefits for users.

Travel distance

The Kailh Box Royal tactile switch and the HMX EVA linear switch both have a travel distance of 3.6 mm, making their travel requirements identical. Consequently, users will experience similar feedback and response when pressing down on the keys of either switch. Since both switches have the same travel distance, typing or gaming on either option should yield comparable results in terms of key actuation and tactile responses, allowing for a consistent experience across both switch types.

Price comparison

Which switch is more bang for your buck?

In other words, finding something perfect for you is, in our view, the most important criteria.

Typing experience

When it comes to sound, the Kailh Box Royal tactile switch produces a high-pitched sound, characterized by a sharp and crisp auditory feedback during keypresses. This sound profile is ideal for users who prefer a lighter, less bassy auditory experience, making it suitable for those who want to avoid the richer tones associated with certain other switches. On the other hand, the HMX EVA linear switch has a resonant sound signature, although specific characteristics are not detailed. However, given its designation as "linear," one might anticipate a smoother, quieter operation compared to the Box Royal, which emits a more pronounced sound due to its tactile nature.

In terms of feel, the Box Royal switch excels with its sharp tactile feedback, providing a pronounced tactile bump that is both aggressive and binary. This intense feedback allows typists and gamers alike to experience a clear indication of actuation with every keystroke. In contrast, the HMX EVA is noted for its silky smooth typing feel, which suggests a very different user experience. While the tactile feedback from the Box Royal might enhance precision in gameplay or typing, the EVA's smoothness indicates that it’s designed for seamless input without the interruption of tactile bumps, appealing to those who prefer a more fluid typing motion.

In conclusion, if you're in the market for switches that cater to different preferences, the Kailh Box Royal tactile switch and the HMX EVA linear switch offer distinct auditory and tactile experiences. The Box Royal is ideal for those who appreciate sharp feedback and a prominent sound profile, while the EVA caters to users looking for a smooth typing experience with a softer auditory signature. The differences in feel and sound will guide your choice depending on your personal preference for typing or gaming, ensuring that you can select switches that align closely with your desired keyboard dynamics.

Conclusion

To conclude, the choice between the Kailh Box Royal tactile switch and the HMX EVA linear switch largely boils down to your typing preferences and the type of experience you want from your keyboard. If you crave a pronounced tactile feedback with each keystroke, then the Box Royal is the right switch for you. Its medium-heavy bottom out force of 70 grams provides a satisfying and sharp tactile response, making it ideal for those who enjoy a more aggressive typing sensation, particularly in typing or gaming scenarios where feedback is crucial. On the other hand, if you prefer a smoother, lighter touch, the HMX EVA with its 48-gram bottom out force would be a better fit. The EVA's linear design ensures a seamless keypress without tactile bumps, perfect for long typing sessions or rapid gameplay where speed is essential. Additionally, the EVA sports a resonant sound profile, contributing to a unique typing experience that contrasts with the higher-pitched auditory feedback of the Box Royal. Ultimately, your choice should reflect how you want your keyboard to feel and sound, so consider these factors carefully to ensure your next mechanical keyboard switch enhances your overall experience.
