Jerrzi Seashell vs. TTC Yunhai
An in-depth look at the Jerrzi Seashell and the TTC Yunhai switches—which one is the best fit for you?
Overview
When it comes to choosing the ideal mechanical keyboard switch, the Jerrzi Seashell and TTC Yunhai stand out as two excellent linear options that cater to different preferences. The Seashell switches are a feast for the eyes with their vibrant purple hue, providing a delightful typing experience characterized by a light and clacky feel that allows for comfortable long-term use. Their combination of aesthetics and functionality make them particularly appealing to keyboard enthusiasts who appreciate both beauty and performance. On the other hand, the TTC Yunhai switches offer a distinct typing experience with a deep, rounded sound profile, and an incredibly light actuation force, perfect for those who favor a gentle and effortless feel when typing. Both switches share a feathery quality, yet they differ in sound and tactile feedback, appealing to varied typing styles. 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 Jerrzi Seashell and the TTC Yunhai, a notable distinction lies in the type of materials used for the top housing. The Seashell's top housing is crafted from polycarbonate, a stiffer plastic that contributes to a sharper and crisper sound profile when typing. This characteristic makes polycarbonate particularly advantageous for users who appreciate a clear and resonant sound, especially when RGB lighting is incorporated. In contrast, the Yunhai employs nylon for its top housing, which is known for its ability to produce a deeper and fuller sound profile. Nylon's softer composition allows it to absorb more sound, resulting in a rounder, less pronounced auditory experience. Thus, the difference in materials leads to contrasting acoustic properties: the Seashell offers a more vibrant sound, while the Yunhai delivers a warmer tone.
On the other hand, both the Jerrzi Seashell and the TTC Yunhai share a commonality in their bottom housing material, which is nylon. This unifying aspect ensures that both switches exhibit similar performance characteristics regarding sound absorption and tactile feedback. Nylon's softer nature contributes to a deeper and fuller sound profile in both switches, creating a rounder bottom-out sensation as the key is pressed down. The use of nylon in the bottom housing means that users can expect a consistent typing experience in terms of sound dampening and tactile response, regardless of the differences in their top housing materials.
Ultimately, the distinct combinations of materials for the top housing of the Seashell and Yunhai create unique sound profiles when typing, emphasizing either clarity or warmth. However, the shared use of nylon in the bottom housing establishes a certain level of auditory and tactile consistency. The sorting of these materials contributes to a versatile switch experience: the Seashell may appeal to those seeking pronounced acoustics ideal for RGB applications, while the Yunhai caters to those who prefer a more subdued typing experience. Regardless of the differences in the top housing, the nylon bottom housing synchronizes their performance on a foundational level, allowing users to enjoy a well-rounded tactile experience across both switches.
Weight
The actuation force and bottom out force of the Jerrzi Seashell and TTC Yunhai linear switches show some interesting contrasts. The Jerrzi Seashell has an actuation force of 45 grams, while the TTC Yunhai is slightly lighter at 42 grams. This difference means that users who prefer a lighter touch will find the Yunhai to their liking, making longer typing sessions or gaming marathons more comfortable. However, the bottom out force of the Seashell remains unknown, whereas the Yunhai's bottom out force is measured at 50 grams, indicating that it offers a more substantial feel when fully pressed down. This can cater to those who enjoy a firmer typing experience. Ultimately, while both switches serve different user preferences with respect to actuation force, the Yunhai is the lighter option overall, providing an easier actuation with a defined bottoming out experience.
Travel distance
When comparing the travel distances of the Jerrzi Seashell linear switch and the TTC Yunhai linear switch, we see a notable difference: the Seashell has a travel distance of 3.4 mm, while the Yunhai measures 3.6 mm. This makes the Seashell the shorter travel option, appealing to those who favor quicker response times, especially beneficial for gamers who prioritize speed. On the other hand, the Yunhai, with its longer 3.6 mm distance, may provide a more substantial, deeper feel, which some users might prefer for a more tactile experience. Ultimately, the choice between the two switches will depend on whether one values responsiveness or a heartier depth in their typing experience.

Typing experience
In terms of sound, the Jerrzi Seashell linear switch is noted for its clacky acoustics, characterized by a sharp and snappy sound when pressed. This results in a crisp, bright, and percussive auditory feedback that can enhance the overall typing experience, particularly for those who find satisfaction in the sound of their keystrokes. On the other hand, the TTC Yunhai linear switch does not have a specifically characterized sound beyond being described as having a deep, rounded profile, which suggests a more subdued acoustic presence compared to the clacky nature of the Seashell. However, it is essential to remember that the overall sound produced by both switches can also heavily depend on the keyboard's build, materials, and keycaps used.
When it comes to feel, both the Seashell and Yunhai switches present a notably light actuation force, contributing to a feathery typing experience. The Seashell excels with its features such as polished and refined key travel, ensuring a smooth and effortless typing experience. It also provides easy-to-press characteristics which minimize finger fatigue during extended use, making it an excellent option for gamers and typists alike. The Yunhai shares this feathery quality, promising an equally light and unstrained feel during use, though it lacks the detailed description of additional characteristics found in the Seashell.
In conclusion, both the Jerrzi Seashell and TTC Yunhai linear switches cater to those who appreciate a light typing experience. The Seashell stands out with its clacky sound and polished, smooth operation, while the Yunhai offers a unique rounded sound profile and an equally light touch. Ultimately, both switches are designed for comfort during long typing sessions, and users can expect a pleasurable experience regardless of their choice, though the Seashell may appeal more to those who enjoy auditory feedback along with a smooth actuating feel.
Conclusion
To conclude, when deciding between the Jerrzi Seashell linear switch and the TTC Yunhai linear switch, it ultimately comes down to your personal preferences regarding sound profile, typing experience, and aesthetic considerations. If you appreciate a light, clacky feel and enjoy the charm of a visually striking purple switch that offers a lively auditory feedback, the Seashell could be your perfect match, especially for long typing sessions where comfort and reduced finger fatigue are essential. On the other hand, if you prefer a truly effortless typing experience paired with a deep, rounded sound that maintains a more subdued tone, the Yunhai is likely the better choice, as its remarkably light actuation force caters to those who desire a smooth, gentle touch while minimizing finger strain. Both switches offer distinct advantages, so consider what elements matter most for your typing needs—whether it be aesthetic appeal, sound preference, or overall feel—and choose accordingly to enhance your mechanical keyboard experience.
