HMX EVA vs. Jerrzi Seashell

Overview

When it comes to mechanical keyboards, the choice of switch can profoundly influence your typing experience, and two intriguing options to consider are the HMX EVA and the Jerrzi Seashell, both linear switches that offer unique characteristics. The HMX EVA stands out with its inspiration from the striking colors of Evangelion Unit-01, delivering a resonant sound signature and a silky smooth typing feel that many users find both comforting and engaging. In contrast, the Jerrzi Seashell captivates with its vibrant purple hue, combining aesthetic beauty with functionality. Known for its light and clacky response, the Seashell switch promises a typing experience that balances ease of use and prolonged comfort, appealing to keyboard enthusiasts who appreciate a joyful interaction. While both switches share the traits of being linear and approachable, they bring distinct flavors to the typing game. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials

The housing materials used in the HMX EVA and Jerrzi Seashell switches reflect distinct characteristics that impact the overall typing experience. The EVA features a nylon top housing, known for its ability to produce a deeper and fuller sound profile. As a softer plastic, nylon absorbs sound more effectively than harder materials, resulting in a muted and rounded sound effect during typing. In contrast, the Seashell utilizes polycarbonate for its top housing, which contributes to a sharper, higher-pitched, and crisper sound profile. The stiffer nature of polycarbonate allows for increased resonance and clarity, meaning that users will experience a more pronounced auditory response when typing. This difference in top housing materials directly impacts the sound quality and tactile feedback that users receive while typing on each switch.

When examining the bottom housing, both the EVA and the Seashell switches are equipped with nylon. This choice means that both switches will share similar properties in terms of sound absorption and feel. The nylon bottom housing provides a deeper and more robust sound when keys bottom out, ensuring that the tactile feedback remains consistent regardless of the differences in the top housing materials. Since both switches utilize nylon in their bottom housing, users can expect a comparable experience when it comes to the feel of the switch as they push down, further solidifying the notion that materials can interplay to create a cohesive typing experience.

In scenarios where the top and bottom housings vary, the characteristics of each material can create a unique fusion of sound and feedback. In this case, the EVA's nylon top housing will produce a more rounded sound on release, while the Seashell's polycarbonate top housing will create a crisper sound profile. However, thanks to the shared nylon bottom housing, both switches retain a familiar baseline in terms of depth and richness during key presses. This interplay between materials allows for a diversified sound experience that can cater to the preferences of different users, blending the advantages of both nylon and polycarbonate in a single switch design.

Weight

When comparing the HMX EVA linear switch and the Jerrzi Seashell linear switch, there are notable differences in their actuation forces. The EVA features a lighter actuation force of 42 grams, making it ideal for users who prefer a more effortless typing experience, especially during extended use, such as for work or long gaming sessions. In contrast, the Seashell has a slightly higher actuation force of 45 grams, catering to those who enjoy a stronger push feel for a more substantial typing experience. While the EVA’s bottom out force is measured at 48 grams, indicating how much force is needed when pressing the switch down completely, the bottom out force for the Seashell remains unknown. As a result, while the EVA can be classified as both lighter in terms of actuation force and has a defined bottom out force, the Seashell may provide a more nuanced experience, though its overall weight characteristics and bottom out dynamics are less clear. Ultimately, users looking for a lighter switch might gravitate towards the EVA, while those who favor a firmer actuation might prefer the Seashell.

Travel distance

When comparing the travel distances of the HMX EVA linear switch and the Jerrzi Seashell linear switch, it becomes evident that there is a measurable difference between the two. The EVA features a travel distance of 3.6 mm, while the Seashell's travel distance is slightly shorter at 3.4 mm. This difference means that the EVA switch provides a more pronounced depth when pressed, which may appeal to users who prefer a fuller tactile experience. On the other hand, the shorter travel distance of the Seashell could be more suitable for gamers seeking quicker response times, as it allows for rapid key actuation. In conclusion, those favoring a more substantial feedback with a depth of 3.6 mm should opt for the HMX EVA, while individuals prioritizing responsiveness may benefit from the quicker response of the 3.4 mm Jerrzi Seashell switch.

Price comparison

Typing experience

In terms of sound, both the HMX EVA and Jerrzi Seashell switches share a clacky sound profile, characterized by a sharp and snappy auditory feedback when engaged. They produce a crisp, bright, and percussive sound that can enhance the overall typing experience. This engaging auditory quality is particularly enjoyable for users who appreciate the tactile and audible feedback of their keystrokes. However, it is essential to note that external factors such as the choice of keyboard board and keycaps can also influence the final sound signature.

When considering their feel, both switches exhibit a light and comfortable typing experience. The EVA switch is described as feathery, silky, and bouncy, offering minimal resistance and fatigue during extended use. The silky aspect ensures a smooth typing experience with a pleasant rebound felt during key presses. Conversely, the Seashell switch is similarly feathery, but it emphasizes an easy-to-press feel with a polished finish, enhancing the overall typing experience by reducing friction. The combination of light actuation force and refined smoothness in both switches will likely prove to be a rewarding experience for users focusing on prolonged typing sessions.

In conclusion, both the HMX EVA and Jerrzi Seashell linear switches cater to enthusiasts seeking an enjoyable and comfortable typing experience. With comparable sound profiles and a range of similar feel descriptors, users can expect a delightful performance from either switch despite their stylistic differences. Ultimately, both switches stand out for their aesthetic appeal and user-friendly qualities, making them suitable choices for anyone interested in mechanical keyboards.

Conclusion

To conclude, your choice between the HMX EVA linear switch and the Jerrzi Seashell linear switch ultimately hinges on your personal preferences and intended use. If you prefer a switch that combines a light actuation force of 48 grams with a uniquely resonant sound and an exceptionally smooth typing experience, the HMX EVA is an excellent choice. Its inspiration from Evangelion Unit-01 not only provides a playful aesthetic but also delivers a feathery, bouncy feel, perfect for long typing sessions whether you're gaming, working, or studying. On the other hand, if you're attracted to a visually stunning purple switch that also emphasizes an easy-to-press mechanism, the Jerrzi Seashell could be your go-to option. The Seashell switches offer both aesthetic appeal and a comfortable typing experience, characterized by their polished finish and lightweight actuation capabilities. Both switches are clacky and enjoyable, so consider your environment and style preference—if you want a vibrant look alongside responsiveness, choose the Seashell; if you seek inspiration and a more refined auditory experience, go with the EVA. Ultimately, either switch will enhance your typing experience, so you can’t go wrong!
