HMX Jammy vs. Jerrzi Poseidon

An in-depth look at the HMX Jammy and the Jerrzi Poseidon switches—which one is the best fit for you?

Overview

When comparing the HMX Jammy and Jerrzi Poseidon mechanical keyboard switches, some key differences stand out. The HMX Jammy is a linear switch known for its softer nylon housings and glittery aesthetics, offering a typing experience that is both muted and deeply satisfying. On the other hand, the Jerrzi Poseidon is also a linear switch, but lacks a standout feature like the Jammy's unique nylon housings. Choosing the Jammy may be ideal for those seeking a softer typing feel, while the Poseidon could be a suitable option for users looking for a more straightforward linear switch. 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 HMX Jammy and the Jerrzi Poseidon, one noticeable difference is the top housing material. The Jammy uses nylon for its top housing, which creates a deeper and fuller sound profile due to its softer plastic nature that absorbs more sound. In contrast, the Poseidon utilizes POM for its top housing, resulting in a more muted and deeper sound profile. While both materials offer unique sound profiles, the nylon in the Jammy provides a duller and rounder sound compared to the relatively more muted sound produced by the POM in the Poseidon.

Moving on to the bottom housing materials, both the HMX Jammy and the Jerrzi Poseidon feature nylon and POM, respectively. The nylon bottom housing in the Jammy contributes to a deeper and fuller sound profile, creating a rounder sound when the switch is pressed down. On the other hand, the POM bottom housing in the Poseidon offers a more muted sound, emphasizing the deeper tones in the sound profile. Despite the different plastic materials used for the bottom housings, both switches aim to provide a satisfying typing experience with their distinctive sound profiles.

In terms of overall typing experience, the top and bottom housing materials play a crucial role in the sound and feel of the switches. While the bottom housing impacts the bottom-out sound and feel when a key is pressed, the top housing influences the sound when a key is released. The nylon and POM materials in the HMX Jammy and the Jerrzi Poseidon work in tandem to create unique sound profiles, with the nylon offering a deeper and fuller sound in the Jammy and the POM providing a more muted and pleasing sound in the Poseidon. Ultimately, the choice between these switches may come down to personal preference in sound and typing feel.

Weight

When comparing the actuation and bottom out forces of the HMX Jammy linear switch and the Jerrzi Poseidon linear switch, it is evident that the Jammy has a higher actuation force of 57 grams compared to the Poseidon's 40 grams, making the Poseidon the lighter option. However, the bottom out force for the Jammy is 63 grams whereas it is unknown for the Poseidon. The Jammy provides a medium actuation and bottom out force, offering a balanced typing experience. In contrast, the Poseidon remains a bit of a mystery in terms of bottom out force. Choosing between the two would depend on whether one prefers a lighter or heavier feel while typing. Lighter switches are ideal for prolonged typing sessions, while heavier switches provide a more substantial typing experience for those who prefer a stronger push feel. Despite the differences in actuation and bottom out forces, selecting either switch would result in similar results for typing and gaming experiences.

Travel distance

When comparing the travel distance of the HMX Jammy linear switch and the Jerrzi Poseidon linear switch, it is evident that the Jammy has a slightly longer travel distance of 3.7 mm compared to the Poseidon's 3.4 mm. Although the difference is minimal, those who prioritize a deeper key press may prefer the Jammy, while individuals looking for a slightly quicker response time might lean towards the Poseidon. Both switches fall within the shorter travel distance range, making them suitable for those who prefer more responsiveness in their keystrokes. Ultimately, the choice between the two switches will depend on personal preference regarding the feel and depth of keystrokes during use.

Typing experience

The HMX Jammy linear switch is known for its medium-weight feel and muted sound due to its softer nylon housing. This combination offers a typing experience that is both satisfying and quiet. On the other hand, the Jerrzi Poseidon linear switch does not have specific information available on its feel or sound characteristics. However, since both switches are linear, it can be assumed that the overall feel and sound may be similar to the Jammy switch. When considering all available information, it is likely that both switches will provide a smooth typing experience with minimal noise, making them suitable choices for those who prefer a quieter keyboard. Ultimately, the decision between the two switches may come down to personal preference and any additional features that each switch may offer.

Conclusion

To sum up, when deciding between the HMX Jammy linear switch and the Jerrzi Poseidon linear switch, you should consider the bottom out force and the typing experience you are looking for. If you prefer a medium bottom out force of 63 grams and a typing experience that is muted yet deeply satisfying, the Jammy switch would be a suitable choice for you. On the other hand, if you are looking for a switch with no specified bottom out force and unique characteristics, you might lean towards the Poseidon switch. Ultimately, your decision should be based on your personal preference for typing feel and the specific features that you prioritize in a mechanical keyboard switch.
