HMX Jammy vs. Bsun Tomcat

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

Overview

When choosing a mechanical keyboard switch, the HMX Jammy and the Bsun Tomcat stand out as appealing options for those seeking a linear typing experience. The Jammy switch is characterized by its softer, glittery nylon housing, delivering a medium-weight feel that ensures a muted yet satisfying response with every keystroke. This makes it an excellent choice for users who prefer a more subdued sound profile while typing or gaming. In contrast, the Tomcat switch is notable for its Ly stems, which provide a remarkably smooth typing experience complemented by a resonant sound profile that adds a dynamic touch to each press. While both switches offer unique benefits, with the Jammy leaning towards a softer and quieter approach and the Tomcat favoring a silky smoothness with an engaging auditory response, the choice ultimately boils down to personal preference in typing feel and sound. However, let's dive in a bit deeper beyond generalities so you can best decide on the switch that suits you most effectively.

Housing materials

When comparing the HMX Jammy and the Bsun Tomcat, a key distinction lies in the materials used for their top housings. The Jammy features a nylon top housing, which is a classic choice that produces a deeper and fuller sound profile. This is due to nylon's softer plastic composition, which tends to absorb sound and results in a more muted auditory experience. In contrast, the Tomcat incorporates a polycarbonate top housing that significantly influences the sound character of the switch. Polycarbonate is a stiffer plastic that facilitates a sharper, higher-pitched sound profile, offering a crisper and clearer auditory feedback. Therefore, while both switches perform effectively, users who prefer a duller and rounder sound may gravitate towards the Jammy, whereas those in the market for a brighter soundscape might find the Tomcat more appealing.

Interestingly, the bottom housings of both the Jammy and the Tomcat utilize nylon, which echoes the benefits related to the material's sound-absorbing properties. This commonality means that users will experience a deeper and fuller sound profile when pressing down on both switches, as the softer nylon material effectively dampens the impact. Despite the differences in their top housings, the nylon bottom provides a consistent auditory experience across both keyboard options. This shared component ensures that both switches offer a comfortable and balanced typing experience, characterized by a less aggressive bottom-out sound.

Ultimately, the divergence in top housing materials creates a nuanced difference in the overall sound profile of the HMX Jammy and Bsun Tomcat. Users can expect a pronounced distinction during the key release sounds due to the contrasting properties of nylon and polycarbonate. While the Jammy emphasizes a smoother, rounder sound upon release, the Tomcat's sharp and crisp auditory feedback might elevate the typing experience for those who enjoy the clarity of each keystroke. Despite these disparities, the combination of nylon in the bottom housing enables both switches to deliver a satisfying tactile experience, allowing users to select the model that best suits their sound preference without compromising on overall performance.

Weight

When comparing the HMX Jammy linear switch and the Bsun Tomcat linear switch, the differences in actuation and bottom out forces are notable. The Jammy requires a heavier actuation force of 57 grams and a bottom out force of 63 grams, making it a more substantial option for those who prefer a stronger tactile feedback while typing. In contrast, the Tomcat has a lighter actuation force of 45 grams and a bottom out force of 54 grams, catering to users who favor a less strenuous typing experience, ideal for long hours of work or gaming. This difference in force means that while the Jammy provides a firmer feel, the Tomcat allows for quicker keystrokes with less effort. Ultimately, the choice between these switches hinges on personal preference, with the Jammy being the heavier option and the Tomcat offering a medium-light experience.

Travel distance

The HMX Jammy linear switch and the Bsun Tomcat linear switch exhibit slightly different travel distances, with the Jammy at 3.7 mm and the Tomcat at 3.6 mm. While both are relatively short compared to the traditional 4.0 mm travel, the Jammy offers a more substantial depth, which some users may find preferable for a more deliberate keystroke experience. Conversely, the Tomcat's slightly shorter travel distance might appeal to gamers and users seeking quicker response times due to its closer alignment with modern preferences for rapid actuation. Ultimately, if you're inclined toward a more responsive feel, the Tomcat would be the ideal choice, whereas those who favor a richer tactile feedback might find the Jammy more suitable.

Typing experience

The sound profile of the HMX Jammy linear switch is characterized as muted, which contributes to a discreet typing experience. This can be particularly appealing in environments where noise is a concern, such as offices or shared spaces. On the other hand, the Bsun Tomcat linear switch is noted for its resonant sound, which may offer a deeper auditory feedback during typing. However, it is essential to remember that the overall sound experience can be influenced by various factors such as the choice of keyboard, mounting type, and keycap material.

In terms of feel, the Jammy switch provides a medium weight and is designed with softer and glittery nylon housings that enhance its tactile feedback. This results in a typing experience that many users find satisfying, especially during prolonged use. Conversely, the Tomcat switch stands out with its Ly stems, which are engineered for a super smooth typing experience. This smoothness can lead to a different sensation under the fingers, making it potentially preferable for users who prioritize effortless keystrokes.

When considering both the HMX Jammy and Bsun Tomcat linear switches, users will find distinct characteristics in sound and feel that cater to different preferences. While the Jammy excels in offering a muted and satisfying experience, the Tomcat provides a more resonant sound coupled with impressive smoothness. Ultimately, the choice between these switches will depend on what qualities matter most to the individual user, but either option can lead to a fulfilling typing experience based on your personal preferences.

Conclusion

To conclude, your choice between the HMX Jammy linear switch and the Bsun Tomcat linear switch should ultimately depend on your preferences for weight and tactile feedback during your typing experience. If you lean toward a medium-weight switch that provides a satisfying bottom-out experience, the Jammy may be the better option for you. Its 63 grams of force contributes to a muted feel, which can make extensive typing sessions more comfortable and less fatiguing. However, if you prioritize a lighter, smoother action with a resonant sound profile, the 54-gram Tomcat might be more appealing. Its unique Ly stems enhance the glide of each keystroke, catering to users who enjoy a quick and effortless typing experience. In terms of sound, the Jammy likely produces a softer thud, while the Tomcat delivers a more resonant auditory feedback. Overall, consider what you primarily seek—satisfying resistance and subtlety versus lightness and smoothness—to make the best choice between these two compelling switches.
