Jerrzi Poseidon vs. TTC Yunhai
An in-depth look at the Jerrzi Poseidon and the TTC Yunhai switches—which one is the best fit for you?
Overview
When exploring the world of mechanical keyboard switches, the Jerrzi Poseidon and the TTC Yunhai stand out as two compelling linear options, each catering to distinct preferences. The Poseidon switch is designed for those who appreciate a smooth and consistent keystroke without the distraction of tactile feedback or an audible click, making it an excellent choice for gamers seeking speed and precision. In contrast, the TTC Yunhai switches are distinguished by their remarkably light actuation force and unique deep sound profile, providing typists with a gentle touch and a satisfying auditory experience. While both switches offer the benefits of linear action, they each appeal to different user preferences—whether you prioritize a quick response for gaming or a soft, enjoyable typing feel. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The Jerrzi Poseidon and the TTC Yunhai utilize different housing materials—POM and nylon, respectively—yet share similarities in their acoustic properties that contribute to a distinct typing experience. The Poseidon's POM housings, both top and bottom, are noted for their unique sound profile that tends to be deeper and more muted, making them appealing for those who enjoy a more subdued auditory feedback while typing. In comparison, the Yunhai's nylon housings, which are a classic choice in the mechanical keyboard world, also deliver a deeper and fuller sound profile. This is due to nylon’s softer nature, which allows it to absorb sound more effectively than harder plastics like POM, resulting in a duller and rounder auditory characteristic. Despite these differences in material, both switches achieve a similar goal of producing a satisfying sound with a deeper resonance, albeit through slightly different mechanisms.
When considering the impact of these housing materials on the overall typing experience, the differences become evident in how each contributes to sound and feel. While the Poseidon’s POM is characterized by a unique and muted sound, the Yunhai’s nylon offers a classic and fuller sound that many users may find familiar. The Poseidon’s muted response may cater to users who prefer a less pronounced keypress, allowing for a quieter action that would be well-suited for both office environments and personal use. In contrast, the Yunhai’s design may attract users who enjoy the enriched auditory feedback that nylon provides, enhancing their typing experience with more pronounced acoustics that can resonate throughout the keyboard.
Ultimately, the effect of the housing materials on the switches illustrates how they influence both the bottom-out sound and key release feel. The bottom housing plays a significant role in defining the tactile feedback and sound profile when a key is pressed down, with POM’s design resulting in a unique and muted sound. Conversely, the top housing influences the sound produced during key release, where the softer properties of nylon allow for a different auditory experience when letting a key go. Whether opting for Jerrzi Poseidon or TTC Yunhai, users can expect a distinct yet satisfying typing experience that reflects the characteristics of housing materials while revealing the nuanced differences in acoustic feedback.
Weight
When comparing the Jerrzi Poseidon linear switch and the TTC Yunhai linear switch, notable differences emerge in their actuation forces. The Poseidon features an actuation force of 40 grams, making it the lighter option compared to the Yunhai, which has an actuation force of 42 grams. This lighter feel of the Poseidon may appeal to those who prefer a more effortless typing experience, especially for extended periods like long work sessions or gaming marathons. Additionally, the bottom out force for the Poseidon is unavailable, whereas the Yunhai has a bottom out force of 50 grams. This suggests that the Yunhai offers a more substantial resistance when fully pressed down, appealing to users who favor a stronger push feel. In summary, while the Poseidon is advantageous for users seeking a lighter switch for prolonged typing comfort, the heavier Yunhai switch provides an enhanced tactile experience for those who appreciate a firmer keystroke.
Travel distance
When comparing the travel distance of the Jerrzi Poseidon linear switch and the TTC Yunhai linear switch, we find that the Poseidon has a travel distance of 3.4 mm, while the Yunhai's travel distance is slightly longer at 3.6 mm. This means that the Jerrzi Poseidon offers a shorter travel distance, making it a potentially better choice for gamers seeking quicker response times, as it allows for faster key actuation. On the other hand, the TTC Yunhai, with its longer travel distance, may appeal to those who prefer a more substantial tactile experience when typing or gaming, offering a sense of depth reminiscent of more traditional switch designs. Thus, while both switches cater to different preferences, the Poseidon’s shorter travel distance may feel more responsive, whereas the Yunhai’s longer travel distance could resonate with users desiring a more pronounced keypress.

Typing experience
When it comes to sound, the Jerrzi Poseidon linear switch does not have notable characteristics that distinguish it from other switches, while the TTC Yunhai linear switch is recognized for its unique deep, rounded sound profile. This sound can provide a rich auditory experience while typing, especially when paired with suitable keycaps and a well-constructed keyboard. The sound produced by the Yunhai can enhance the overall feel of the typing experience, making it more enjoyable for those who appreciate acoustics as part of their setup.
In terms of feel, the Jerrzi Poseidon linear switch lacks defined attributes in this context, which makes it difficult to assess its tactile experience. In contrast, the TTC Yunhai linear switch stands out with its incredibly light actuation force. This gentleness allows for a very effortless typing experience, catering to typists who appreciate a smooth and swift keypress. The lighter feel can reduce finger fatigue during long typing sessions, offering a notable advantage for those who type extensively.
Overall, while the Jerrzi Poseidon linear switch lacks specific defining qualities in both sound and feel, the TTC Yunhai linear switch offers a distinct deep sound profile and a lighter actuation force for a more comfortable typing experience. Consequently, if acoustic feedback and a gentle touch are important in your typing journey, the Yunhai switch is clearly advantageous. However, if you prefer a more neutral or unspecified experience, the Poseidon might suit your needs just as well, allowing for a similar overall typing experience depending on other keyboard factors.
Conclusion
To conclude, choosing between the Jerrzi Poseidon linear switch and the TTC Yunhai linear switch ultimately comes down to your personal preferences and typing habits. If you are someone who enjoys a particularly light and effortless typing experience, the Yunhai is the clear winner with its 50-gram bottom out force, making it ideal for extended typing sessions where fatigue is a concern. Furthermore, its distinct deep and rounded sound profile adds an enjoyable auditory element to your typing, which can enhance the overall experience. On the other hand, if you find that the traits of the Poseidon better suit your style, perhaps due to a specific tactile feel you’re after, or if you've heard good things about its performance despite not having available specifications, then it may be worth trying. Ultimately, the choice depends on what you value more: the effortless actuation and unique acoustics of the Yunhai or the unexplored qualities of the Poseidon that may align with your typing satisfaction. Give both a try if possible, and enjoy the journey of discovering which switch feels best for you!
