Jerrzi Poseidon vs. SP-Star Yanyu
An in-depth look at the Jerrzi Poseidon and the SP-Star Yanyu switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, the Jerrzi Poseidon and the SP-Star Yanyu both offer unique features and qualities to consider. The Poseidon is a linear switch that is best known for its smooth keystrokes and consistent actuation. On the other hand, the Yanyu linear switch stands out for its delicate typing experience and crisp sound profile, making it ideal for those who type for long periods of time. The Yanyu switch is categorized as 'Neutral', 'Mild', 'Thocky', 'Feathery', 'Subtle', and 'Polished', offering a variety of qualities to enhance the typing experience. While the Poseidon is more of a general-purpose linear switch, the Yanyu excels in providing a refined and satisfying typing experience. 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 of the Jerrzi Poseidon and SP-Star Yanyu switches both offer unique sound profiles that cater to different preferences. The Poseidon's POM top and bottom housing create a deeper and more muted sound, providing a distinctive typing experience. On the other hand, the Yanyu's Polymer nylon and UHMWPE blend top and bottom housing produce a brighter sound that is equally pleasant. While the Poseidon offers a more subdued typing experience, the Yanyu delivers a slightly sharper sound that may appeal to those looking for a livelier feel.
Despite their differences, both switches incorporate unique housing materials that contribute to their overall sound profile. The POM housing of the Poseidon delivers a deep and muted sound profile that is consistent across both the top and bottom housing. In contrast, the Yanyu's blend of Polymer nylon and UHMWPE offers a brighter sound profile that is evident in both the top and bottom housing. While the specific qualities of each material differ, both switches provide a satisfying typing experience that showcases the potential of innovative housing materials in mechanical keyboards.
When considering the impact of housing materials on switch performance, it is important to note how the qualities of the top and bottom housing can influence the overall typing experience. The bottom housing of a switch, whether it be POM or a blend of materials like the Yanyu, plays a significant role in the bottom-out sound and feel when a key is pressed. Conversely, the top housing of a switch has a more pronounced effect on the sound produced when a key is released. By understanding the unique characteristics of each housing material, keyboard enthusiasts can tailor their typing experience to suit their preferences and choose a switch that best meets their needs.
Weight
The Jerrzi Poseidon linear switch has a lighter actuation force of 40 grams compared to the SP-Star Yanyu linear switch, which has an unknown actuation force. However, the Yanyu switch has a lighter bottom out force of 43 grams, while the bottom out force of the Poseidon switch is unknown. Those who prefer a lighter typing experience may lean towards the Poseidon switch for its lower actuation force, while those who prefer a more substantial feel may opt for the Yanyu switch with its heavier bottom out force. Both switches offer different weights for actuation and bottom out, so users can choose based on their preference for typing feel.
Travel distance
In comparing the travel distance of the Jerrzi Poseidon linear switch and the SP-Star Yanyu linear switch, it is evident that the Poseidon has a shorter travel distance of 3.4 mm, while the Yanyu has a longer travel distance of 4mm. The Poseidon's shorter travel distance may appeal to gamers seeking faster response times, while the Yanyu's longer travel distance may be preferred by those who enjoy a deeper key press experience. Both switches fall within the range of traditional travel distances and can offer a satisfying typing or gaming experience depending on individual preferences. The Poseidon may provide a more immediate response, while the Yanyu may offer a more substantial key press sensation. Ultimately, the choice between the two switches will depend on personal preference for travel distance and key press feel.
