Jerrzi Poseidon vs. HMX Xinhai (Heavy)
An in-depth look at the Jerrzi Poseidon and the HMX Xinhai (Heavy) switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, the choice between the Jerrzi Poseidon and the HMX Xinhai (Heavy) linear switches offers enthusiasts distinct characteristics that cater to different preferences and typing experiences. The Poseidon switch stands out as a reliable option for those who prefer smooth keystrokes without any tactile feedback or audible click, making it an attractive choice for gamers and typists alike who favor fast, uninterrupted typing sessions. On the other hand, the HMX Xinhai (Heavy) takes the linear switch experience up a notch with its unique PA12 top housing, which enhances acoustics for a softer sound profile, combined with a POM stem that produces a crisp, higher-pitched resonance—ideal for users who appreciate a touch of refinement alongside solid performance. Both switches offer a linear feel that eliminates the bumps of tactile switches, but their distinct audio characteristics and build materials cater to different desires in the realm of keyboard feedback. 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 Poseidon and the HMX Xinhai (Heavy), it becomes evident that both switches utilize different plastics for their top and bottom housings, which influences their sound profiles and tactile experiences. The Poseidon employs POM (Polyoxymethylene) for both its top and bottom housings, which are well-regarded for producing a unique, deeper, and more muted sound. This consistency in housing material may deliver a more cohesive auditory experience when typing, as the materials are designed to complement each other, resulting in a pleasing sound profile that users might find appealing.
In contrast, the HMX Xinhai (Heavy) utilizes nylon for both its top and bottom housings. Nylon, known for its softer composition compared to POM, contributes to a deeper and fuller sound profile as well. The softer material absorbs more sound, leading to a rounder auditory experience that may be perceived as warmer compared to the deeper and more muted sound of the Poseidon. This variation in materials suggests a different sensibility; while both switches aim for a satisfying sound experience, the Xinhai’s nylon may provide a slightly different tactile feedback due to its absorption properties.
Despite the differences in materials, it’s important to note that both switch types aim for a similar result—a pleasing sound profile, albeit with different characteristics. For the Poseidon, the POM creates a unique and muted resonance, while the nylon in the Xinhai offers a fuller and rounder sound. Ultimately, the choice between these switches depends on user preference regarding sound quality and tactile feedback. For users looking for a muted and unique auditory experience, the Jerrzi Poseidon may be preferable, whereas those desiring a warmer and fuller sound profile may gravitate towards the HMX Xinhai (Heavy). The interaction of the top and bottom housings in both switches ensures that the sound and feel will vary, even if some users may find them similarly enjoyable in different ways.
Weight
The Jerrzi Poseidon linear switch and the HMX Xinhai (Heavy) linear switch present notable differences in their actuation forces, which impact their usability for various preferences. The Poseidon has a lighter actuation force of 40 grams, making it more suitable for users who prioritize comfort and ease during extended typing sessions, whether at work or during long gaming marathons. In contrast, the Xinhai (Heavy) switch features a higher actuation force of 55 grams, appealing to those who favor a more substantial feel and tactile feedback when typing. However, while the Poseidon’s bottom out force remains unspecified, the Xinhai offers a bottom out force of 62.5 grams, indicating a firmer end to the keystroke that may resonate well with users who prefer stronger tactile responses. Overall, if you're looking for a lighter switch, the Poseidon is the way to go, whereas the Xinhai (Heavy), with its heavier forces, caters to those who enjoy a more robust typing experience.
Travel distance
Both the Jerrzi Poseidon linear switch and the HMX Xinhai (Heavy) linear switch feature an identical travel distance of 3.4 mm, meaning they provide the same tactile feedback when a key is pressed down. This similarity ensures that users will experience comparable results in terms of keypress depth and overall response, making either switch a suitable choice for those who favor a linear feel without the added resistance found in tactile or clicky switches. Since both switches have the same travel distance, users can confidently choose between them based on other factors such as actuation force or personal preference in design rather than distance alone.

Typing experience
The sound profile of the Jerrzi Poseidon linear switch is not specified, leaving its acoustic qualities open to interpretation. In contrast, the HMX Xinhai (Heavy) linear switch is noted for its softer acoustics, attributed to its unique PA12 top housing. This design choice allows the Xinhai to produce a distinctively crisp, higher-pitched resonance thanks to its POM stem. This combination of materials offers a subtle sophistication that can provide an engaging auditory experience, making it ideal for users who appreciate a refined sound without being overly loud or disruptive.
When it comes to feel, the Poseidon linear switch does not have detailed characteristics provided, leaving newcomers to wonder about its tactile response and actuation qualities. On the other hand, the Xinhai (Heavy) switch is designed to embody precise performance, potentially offering a satisfying and responsive touch when pressed. The heavy variant implies that it may require a stronger actuation force, which some users might prefer for a more deliberate typing experience, making it suitable for individuals who enjoy a robust feedback with each keystroke.
Overall, while the quality of sound for the Poseidon remains unknown and the specific tactile sensation is similarly unspecified, the HMX Xinhai (Heavy) provides clear descriptions of both auditory and physical attributes. Users seeking a switch with a crisp sound profile and a reliable tactile feel may lean toward the Xinhai (Heavy) to enjoy its unique qualities. However, if the goal is to find a switch that complements personal preferences, the Poseidon might still be a viable option, but further exploration is warranted to fully understand its characteristics.
Conclusion
To conclude, choosing between the Jerrzi Poseidon linear switch and the HMX Xinhai (Heavy) linear switch ultimately comes down to your personal preferences and typing experience. If you seek a switch that feels light and offers a smooth, effortless keystroke experience without a defined bottom-out force, the Poseidon may be your go-to choice. This switch could be particularly appealing if you prioritize rapid key presses for gaming or a softer tactile response for extended typing sessions. On the other hand, if you prefer a switch with a more substantial feel, the HMX Xinhai (Heavy) with its 62.5 grams of bottom-out force will provide that satisfying resistance, making it ideal for users who enjoy tactile feedback and a more deliberate typing style. The Xinhai's unique materials also offer a refined acoustics profile, making it a great option if sound quality and a higher-pitched resonance are important to you. In summary, consider the Poseidon for a lighter, effortless experience and the Xinhai for a sturdy feel with enhanced sound characteristics. Choose based on your usage patterns and tactile preferences to find the perfect match for your mechanical keyboard setup.
