HMX EVA vs. SP-Star RedBlue
An in-depth look at the HMX EVA and the SP-Star RedBlue switches—which one is the best fit for you?
Overview
When choosing the perfect mechanical keyboard switch for your typing or gaming needs, the HMX EVA and the SP-Star RedBlue present two intriguing options, both classified as linear switches but with distinctive traits. The HMX EVA is inspired by the vibrant colors of Evangelion Unit-01, boasting a resonant sound signature that contributes to a unique auditory experience, paired with a silky smooth typing feel that many users find satisfying. In contrast, the SP-Star RedBlue offers a medium-light typing experience and is characterized by its low-pitched, neutral sound profile, making it a popular choice for those who seek a more understated auditory feedback. While both switches provide linear smoothness ideal for fast-paced typing and gaming, their distinctive sound characteristics and tactile experiences cater to different preferences. 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 SP-Star RedBlue switches, it is evident that both utilize distinct types of plastics that influence the auditory and tactile feedback offered by each switch. The HMX EVA features a nylon top and bottom housing, yielding a deeper, fuller sound profile characterized by warmth and resonance. This is attributable to nylon's softer composition, which helps absorb sound, resulting in a more rounded auditory experience. In contrast, the SP-Star RedBlue employs polycarbonate for both its top and bottom housings, producing a sharper and more resonant sound. Polycarbonate's rigidity contributes to a crisp auditory profile, making each keystroke feel and sound more precise and clear.
Despite the differences in the materials used, both switches can achieve similar results in terms of overall performance, depending on user preferences and typing styles. While users of the EVA may appreciate the softer, muffled tones for a more subdued typing experience, those favoring the RedBlue might lean towards its sharper sounds that complement RGB lighting setups effectively thanks to the material's translucency. Ultimately, the choice between the two would depend on whether one prioritizes a warm, deep sound versus a striking, high-pitched auditory response.
In addition, it's essential to consider how the unique attributes of each material will affect the overall experience. The nylon housings of the EVA contribute to a comforting and muted typing experience that many might find suitable for extended usage or quieter environments. Conversely, the polycarbonate of the RedBlue excels in settings where clarity and definition are paramount or where aesthetic lighting effects are desired. As both switches offer a distinct sound profile and feel due to their materials, users can find satisfaction in either choice based on individual auditory preferences and functional requirements, albeit expressed through different sensory experiences.
Weight
When comparing the HMX EVA linear switch and the SP-Star RedBlue linear switch, significant differences in their actuation and bottom out forces emerge. The HMX EVA features a light actuation force of 42 grams and a bottom out force of 48 grams, making it an excellent choice for users who prefer a lighter typing experience, suitable for extended use during long typing sessions or gaming marathons. In contrast, the SP-Star RedBlue switch has an unspecified actuation force but possesses a higher bottom out force of 57 grams, categorizing it as medium-light. This implies that while the bottoming-out experience may feel more substantial than the EVA, the lack of specified actuation force hinders a direct comparison. Overall, the EVA switch is the lighter option, while the RedBlue offers a heavier bottom out feel, catering to different user preferences in typing dynamics.
Travel distance
The HMX EVA linear switch features a travel distance of 3.6 mm, while the SP-Star RedBlue linear switch has a slightly longer travel distance of 4 mm. This means that the EVA offers a shorter actuation distance compared to the RedBlue, which can be advantageous for users who prioritize responsiveness, such as gamers, as it allows for quicker key presses. On the other hand, the RedBlue's longer travel distance may appeal to those who prefer a more substantial feel while typing, as it provides a deeper and more pronounced actuation experience. Ultimately, if you opt for the EVA switch, you'll likely experience a quicker actuation, while the RedBlue will offer a more traditional feel with its greater travel distance.

Typing experience
The sound profile of the HMX EVA linear switch is characterized by a resonant quality that may appeal to those who enjoy a more dynamic auditory experience while typing. This resonant signature can add a unique character to keystrokes, likely enhancing the overall typing atmosphere. In contrast, the SP-Star RedBlue linear switch presents a low-pitched sound, offering a mellow and deep tone that is generally described as thocky. This quality contributes to a satisfying auditory feedback, making it a solid choice for users who appreciate a more subdued yet rich soundscape. Both switches provide auditory feedback that can be influenced by their accompanying keycaps and keyboard design, but each has its distinct characteristics; the EVA’s resonance versus the RedBlue's bass-heavy thock.
When it comes to the feel, the HMX EVA linear switch is known for its silky smooth typing experience, which suggests a seamless key travel devoid of any hindrances. This refined touch can lead to a pleasurable and efficient typing experience, especially for those who prioritize a smooth keystroke. On the other hand, the SP-Star RedBlue switch delivers a mild and polished feel. The mildness makes it accessible to a wider range of users, while the polished finish ensures a fluid and smooth interaction with each keystroke. In essence, while the EVA’s smoothness provides an extraordinary silk-like sensation, the RedBlue's gentle and polished characteristics make it approachable for all types of typists.
In summary, both the HMX EVA and SP-Star RedBlue linear switches offer distinct qualities that cater to different user preferences. The EVA switch stands out with its resonant sound and silky smooth feel, appealing to those seeking a more vibrant and fluid typing experience. Conversely, the RedBlue excels in providing a low-pitched, thocky sound coupled with a mild and polished feel, making it a versatile choice for those who appreciate a balanced and refined typing performance. Ultimately, your choice will depend on whether you lean towards a more dynamic auditory and tactile sensation or a subdued, approachable typing experience.
Conclusion
To sum up, choosing between the HMX EVA linear switch and the SP-Star RedBlue linear switch ultimately depends on your personal preferences and typing needs. If you appreciate a lighter touch with a force of 48 grams and desire a silky smooth typing experience accompanied by a resonant sound, the EVA would be your best option. It's particularly well-suited for those who enjoy a more playful aesthetic, as its design is inspired by iconic pop culture. On the other hand, if you prefer a slightly heftier feel at 57 grams along with a more neutral and low-pitched sound profile, the RedBlue switch would be more to your liking. Its polished and mild characteristics make it an excellent choice for both beginners and experienced typists looking for a consistent and pleasant tactile experience. In essence, if you're after a vibrant sound and a lightweight feel, go for the EVA; however, if you favor a balanced typing experience with a bit more resistance, the RedBlue will serve you well.
