HMX Blue Topaz vs. HMX EVA
An in-depth look at the HMX Blue Topaz and the HMX EVA switches—which one is the best fit for you?
Overview
When it comes to selecting the ideal mechanical keyboard switch, the HMX Blue Topaz and HMX EVA offer intriguing options, each with its unique characteristics that cater to different preferences. The HMX Blue Topaz distinguishes itself with its super smooth actuation and lightweight feel, ensuring that every keystroke feels effortless and fluid. Its eye-catching glittery housing is complemented by a clacky sound signature, making it not only a joy to type on but also a visual treat. On the other hand, the HMX EVA, drawing inspiration from the iconic Evangelion Unit-01, boasts a resonant sound signature and a silky smooth typing experience, perfect for those who appreciate a more subdued auditory feedback while retaining a comfortable keystroke feel. While the Blue Topaz appeals to users who enjoy a lively typing experience with a strong tactile presence, the EVA caters to those who prefer a smoother, quieter approach. However, let's dive in a bit deeper beyond generalities so you can best decide on the ideal switch for you.

Housing materials
The HMX Blue Topaz and HMX EVA exhibit notable differences in their top housing materials, which significantly influence their sound profiles and overall typing experience. The Blue Topaz features a polycarbonate top housing that is recognized for producing a sharp, higher-pitched, and crisper sound due to its stiffer nature. This material's translucency not only enhances the aesthetics, especially for RGB lighting effects, but also contributes to a more resonant sound profile. In contrast, the EVA utilizes a nylon top housing that creates a deeper, fuller sound. The nylon's softer composition absorbs sound more effectively than the harder polycarbonate, resulting in a rounder and more subdued auditory profile. Thus, while both housings play critical roles in the typing experience, the materials used distinctly shape the character of the sound produced.
When examining the bottom housings, both the Blue Topaz and EVA utilize nylon material, ensuring consistency in the sound generated when bottoming out. As noted, nylon is a classic switch housing material that helps create a deeper and fuller sound profile. This shared characteristic allows both switches to produce a duller, rounder sound as the softness of nylon significantly dampens vibrations compared to harder plastics. In this aspect, each switch benefits from the advantages of nylon, leading to a more comfortable typing experience with less harshness during impact. Ultimately, this means that while the top housings differ in their sound signatures, the bottom housings marry their acoustic properties, lending a cohesive quality to the overall experience.
In summary, the combination of polycarbonate in the Blue Topaz's top housing and nylon in both the Blue Topaz’s and EVA's bottom housings creates a unique contrast between the two switch types. The polycarbonate top housing elevates the sound profile with bright clarity, while the nylon bottom housing ensures a fuller sound experience when the keys are pressed down. Conversely, the EVA's consistent application of nylon in both housings results in a universally softer and rounder sound profile. Despite the difference in top housing materials, users can expect a degree of similarity in overall performance with both switches, primarily dictated by the nylon's influence in the bottom housing design. Therefore, while the tactile experience may vary, users can achieve desirable results with both switches based on their intended use and personal sound preferences.
Weight
When comparing the HMX Blue Topaz linear switch and the HMX EVA linear switch, both exhibit relatively light weights, making them favorable for prolonged typing sessions or gaming marathons. The Blue Topaz has an actuation force of 40 grams and a bottom out force of 48 grams, while the EVA requires a slightly heavier actuation force of 42 grams, with the same bottom out force of 48 grams. This means that while both switches bottom out at the same force, the EVA provides a marginally heavier feel during the actuation, which may appeal to users who prefer a more substantial typing experience. Consequently, the Blue Topaz can be seen as the lighter option overall, making it suitable for those who prioritize ease and comfort over tactile resistance.
Travel distance
The HMX Blue Topaz linear switch features a travel distance of 3.9 mm, while the HMX EVA linear switch has a shorter travel distance of 3.6 mm. This means that when pressing down on a key, the Blue Topaz offers a more pronounced depth compared to the EVA switch. For those who favor a more responsive feel, the EVA's shorter travel distance might be appealing, as it allows for quicker actuation, which can enhance performance in fast-paced gaming scenarios. Conversely, the Blue Topaz provides a more substantial travel experience, which some users might prefer for its tactile feedback and stability. Therefore, if you prioritize rapid response times, the EVA is the better choice, while the Blue Topaz caters to those who enjoy a deeper keypress.

Typing experience
When it comes to sound, the HMX Blue Topaz linear switch stands out with its distinctive clacky sound signature. This produces a sharp, snappy sound upon actuation, giving users an auditory experience that is both crisp and percussive. The clacky nature can add a layer of enjoyment for those who appreciate an acoustically lively keyboard. In contrast, the HMX EVA’s sound signature is resonant but lacks specific descriptors; thus, while it may also be pleasant, its exact auditory qualities remain unknown. The sound of both switches can vary based on the keyboard construction and keycap choice, but the Blue Topaz provides a clear expectation of a lively auditory response.
In terms of feel, the HMX Blue Topaz clearly excels with its easy-to-press characteristics. This switch requires minimal force to activate, allowing for effortless typing and reducing the risk of finger fatigue, especially during long typing sessions. Its lightweight actuation not only enhances comfort but also contributes to a more enjoyable overall typing experience. The feel of the HMX EVA, however, remains unspecified. Currently, there's no user feedback or specific descriptors available for its tactile quality, making it difficult to provide a direct comparison in feel.
In summary, while the HMX Blue Topaz linear switch presents a delightful combination of a clacky sound and an easy-to-press feel, the characteristics of the HMX EVA remain more nebulous. If you're leaning towards a fun and engaging auditory experience along with comfort during typing, the Blue Topaz emerges as a clear choice. However, if you're interested in trying out the EVA, you may still achieve a pleasurable experience, albeit with less certainty regarding its specific sound and feel qualities.
Conclusion
To wrap up, your choice between the HMX Blue Topaz and the HMX EVA linear switches will ultimately depend on your personal preferences regarding sound, aesthetics, and tactile experience. If you favor a unique visual appeal combined with a clacky sound signature that offers an engaging auditory experience while typing, the Blue Topaz is the perfect fit for you. Its lightweight actuation provides a comfortable and effortless typing experience, making it an excellent choice for long hours at the keyboard without finger fatigue. On the other hand, if you are drawn to a more subdued aesthetic and a silky smooth feel while still enjoying a resonant sound, the HMX EVA is worth considering. While it shares a similar actuation force with the Blue Topaz, the EVA promises a different auditory profile and design inspired by a beloved pop culture icon. In summary, choose the Blue Topaz for a lively, dynamic typing experience, or go for the EVA for a sleek, smooth affair with a hint of nostalgia.
