HMX EVA vs. Gazzew U4T

An in-depth look at the HMX EVA and the Gazzew U4T switches—which one is the best fit for you?

Overview

When choosing the right mechanical keyboard switch, two compelling options to consider are the HMX EVA and the Gazzew U4T. The HMX EVA, inspired by the iconic colors of Evangelion Unit-01, is a linear switch that offers a silky smooth typing experience complemented by a resonant sound signature. This switch is ideal for users who prioritize a quiet, seamless keystroke and enjoy the fluidity of linear actuation, making it perfect for gaming or prolonged typing sessions. In contrast, the Gazzew U4T is a tactile switch that delivers a delightful blend of thockiness and sharp tactility, featuring a bassy 'thock' sound profile that provides both auditory and tactile satisfaction. This switch is favored by typists and gamers alike who appreciate the pronounced feedback and satisfying sound with each keystroke. Both switches have their unique appeals—whether it’s the smooth grace of the EVA or the responsive character of the U4T. 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 EVA and Gazzew U4T offer intriguing comparisons in their housing materials, specifically regarding the top and bottom components. The EVA utilizes a traditional nylon for its top housing, which is praised for its softer texture that provides a deeper and fuller sound profile. This is notable because nylon effectively absorbs sound, leading to a more muted auditory experience, which many typists find desirable. In contrast, the U4T employs a proprietary Gazzew blend, often referred to as "boba plastic." Despite being a different formulation, this blend shares a commonality with nylon in that its softness contributes to a rich and deep sound profile, suggesting that both materials foster a more pleasant typing experience through sound absorption.

Delving deeper into the bottom housing components, both switches maintain a consistent theme in the use of softer materials. Like the top housing, the bottom housing of the EVA is also crafted from nylon, ensuring that the deeper sound characteristics are preserved through the actuation. Meanwhile, the U4T’s use of its proprietary blend for the bottom housing continues to emphasize a similar theme of sound richness and cushioning upon bottoming out. While the materials differ, the outcome remains fairly aligned: both switches offer an auditory experience that is gratifying and resonant, which is a significant aspect of typing comfort and functionality.

Ultimately, the differences in material primarily lie in the characteristics of the plastics used—nylon versus a proprietary blend. Nevertheless, since both switches engage soft materials in both top and bottom housings, users can expect comparable auditory feedback and a satisfying typing experience overall. The EVA's nylon and the U4T's Gazzew blend may each contribute distinctively to their respective sound profiles, but both are designed to minimize harshness and maximize depth. Thus, whether one opts for the classic feel of nylon or the innovative Gazzew formulation, both switches share the ability to deliver a similar pleasurable typing experience through their inherent sound-absorbing qualities.

Weight

When comparing the HMX EVA linear switch and the Gazzew U4T tactile switch, there are notable differences in their actuation and bottom out forces. The EVA features a lighter actuation force of 42 grams and a bottom out force of 48 grams, making it suitable for users who prefer a less strenuous typing experience, ideal for prolonged use during work or gaming sessions. In contrast, the U4T's actuation force is unspecified, while its bottom out force is significantly higher at 65 grams, indicating a medium-heavy resistance that caters to those who enjoy a more tactile and substantial typing feel. As a result, users seeking a lighter switch should opt for the HMX EVA, while those who appreciate weightier feedback in their keystrokes would prefer the Gazzew U4T. Overall, this comparison illustrates how each switch targets different preferences based on actuation and bottom out forces.

Travel distance

When comparing the travel distances of the HMX EVA linear switch and the Gazzew U4T tactile switch, the EVA measures 3.6 mm, while the U4T has a slightly longer travel distance of 4 mm. This means that the EVA provides a shorter actuation distance, making it more responsive for tasks that require quick keystrokes, such as gaming. On the other hand, the U4T's longer travel distance offers a more pronounced feel and depth, which some users may prefer for a more tactile typing experience. Thus, if responsiveness is a priority, the EVA is the way to go, while those seeking a more substantial feel may gravitate toward the U4T. Overall, the EVA's 3.6 mm travel distance positions it as the shorter option, in contrast to the U4T's 4 mm length.

Typing experience

In terms of sound, the HMX EVA switch is characterized by a resonant sound signature that enhances the overall typing experience. Although specific descriptors for its sound are not provided, it is generally recognized for its smooth and pleasant auditory feedback that complements its silky typing feel. On the other hand, the Gazzew U4T switch offers a bassy and thocky profile, producing a deep, resonant thud with each keystroke. This sound contributes to a rich auditory environment, akin to the satisfaction that comes from a well-tuned instrument, making it highly appealing for enthusiasts who enjoy sharper, more pronounced auditory feedback.

When it comes to feel, the EVA switch is known for its silky smooth typing experience, allowing for effortless keystrokes that glide without resistance. This makes it a suitable option for those who prioritize a frictionless typing experience. Conversely, the U4T switch is famed for its sharp tactile feedback, providing a distinct and assertive bump with every keystroke. This type of tactile response gives the user clear confirmation of activation, engaging those who appreciate the tactile sensation while typing or gaming.

In summary, while the HMX EVA and Gazzew U4T switches differ significantly in both sound and feel, they each cater to distinct preferences. The EVA switch provides a smooth and resonant auditory experience, ideal for users seeking a gentle typing sensation, whereas the U4T excels with its pronounced thocky sound and sharp tactile feedback, perfect for those who enjoy dynamic auditory and tactile stimulation. When choosing between these two, consider your personal preference for either a smooth or an assertive typing experience, as well as the type of sound profile you find most satisfying.

Conclusion

To conclude, when deciding between the HMX EVA linear switch and the Gazzew U4T tactile switch, you'll want to consider your personal preferences and usage scenarios. If you prioritize a lighter feel and smoother keystrokes, particularly for fast typists or gamers, the EVA is an excellent choice. Its 48 gram bottom-out force allows for effortless key presses, making it well-suited for long typing sessions and gaming marathons where speed is a priority. Additionally, the EVA’s resonant sound signature enhances the typing experience without overwhelming it, appealing to those who enjoy a more understated audio profile. Conversely, if you're someone who values tactile feedback and a more pronounced auditory experience, the Gazzew U4T will serve you well. With a heavier resistance of 65 grams, this switch offers a satisfying thocky sound and sharp tactile bump, providing a blend of auditory enjoyment and physical feedback that can enhance your typing precision and satisfaction. Ultimately, your choice should reflect whether you lean towards a smoother, lighter switch for speed or a more tactile, audible switch for feedback and pleasure in your keystrokes.
