HMX Jammy vs. HMX Xinhai (Heavy)
An in-depth look at the HMX Jammy and the HMX Xinhai (Heavy) switches—which one is the best fit for you?
Overview
When it comes to choosing a mechanical keyboard switch, the HMX Jammy and HMX Xinhai (Heavy) offer two distinct yet appealing options for users who prefer linear switches. The Jammy is celebrated for its medium-weight feel and softer, glittery nylon housings, providing a typing experience that is both muted and deeply satisfying, making it an excellent choice for those who value a comfortable and less intrusive sound while typing. In contrast, the Xinhai (Heavy) takes a different approach with its unique PA12 top housing, which enhances acoustic softness, paired with a POM stem that delivers a crisp, higher-pitched resonance. This switch caters to users who enjoy a refined and precise typing experience. Each switch brings its own strengths to the table, from the Jammy’s comfort and subdued sound to the Xinhai’s sophistication and clarity. However, let's dive in a bit deeper beyond generalities so you can best decide on the switch that suits your personal preferences.

Housing materials
The HMX Jammy and the HMX Xinhai (Heavy) both feature nylon as their primary housing material, with identical descriptions highlighting nylon's characteristics. The uniformity in the use of nylon for both the top and bottom housings in these switches suggests that users can expect similar auditory experiences when typing. As a classic switch housing material, nylon's softer qualities lend themselves to creating a deeper and fuller sound profile, absorbing more sound than harder plastics. This consistent choice in housing material ensures that both switches produce a duller and rounder sound, contributing to a satisfying acoustic experience during use.
Additionally, since both the Jammy and the Xinhai (Heavy) utilize nylon for both top and bottom housing, the typing sensations will also be comparable. The bottom housing's softer plastic enhances the bottom-out sound and feel, while the top housing's contribution is more pronounced during the release of the key. Both switches will, therefore, provide the user with a seamless tactile experience characterized by the comforting depth that nylon inherently offers. The intricacies of typing on these switches will be similarly enjoyable due to the shared performance attributes attributable to nylon's acoustic and tactile properties.
Ultimately, while there are no differences in the housing materials of the HMX Jammy and the HMX Xinhai (Heavy), the outcome remains beneficial for users of both switches. The identical nylon housings mean that players, typists, or anyone who engages with these switches will experience a similar sound profile, tactility, and overall satisfaction. The design choice to employ nylon ensures that both models deliver noteworthy performance, reinforcing the notion that housing materials can play a significant role in the typing experience and sound profile, even when the materials themselves are the same.
Weight
When comparing the actuation and bottom out forces of the HMX Jammy linear switch and the HMX Xinhai (Heavy) linear switch, we see some notable similarities and differences. The Jammy requires an actuation force of 57 grams and has a bottom out force of 63 grams, while the Xinhai (Heavy) requires a slightly lighter actuation force of 55 grams and has a bottom out force of 62.5 grams. In this case, both switches fall into the medium weight category, making them suitable for a variety of typing preferences. The Jammy is the heavier option overall, but the differences in force are minimal, meaning that users will likely experience similar typing results with either switch. For those who prefer a lighter feel for extended typing or gaming sessions, the Xinhai (Heavy) may be the better choice due to its lower actuation force. Conversely, individuals who enjoy a more substantial push are likely to appreciate the slightly heavier feel of the Jammy.
Travel distance
When comparing the travel distances of the HMX Jammy linear switch and the HMX Xinhai (Heavy) linear switch, the Jammy features a travel distance of 3.7 mm, while the Xinhai (Heavy) has a travel distance of 3.4 mm. This means that the Jammy offers a longer travel distance, providing a more pronounced key press that some users may find more satisfying, particularly those who prefer a tactile depth in their typing experience. In contrast, the shorter travel distance of the Xinhai (Heavy) can contribute to quicker response times, making it more suitable for gamers who prioritize speed and efficiency in their keystrokes. Ultimately, if you prefer a switch with a more responsive feel, the Xinhai (Heavy) may be the better choice, whereas the Jammy may appeal to those who enjoy a fuller key press sensation.

Typing experience
When it comes to sound, the HMX Jammy linear switch delivers a muted auditory experience with its softer nylon housings. The design prioritizes a more subdued aural feedback, which contributes to an overall satisfying typing experience that feels gentle on the ears. In contrast, the HMX Xinhai (Heavy) switch offers a more crystalline resonance, thanks to its PA12 top housing and POM stem. This combination produces a distinctively crisp and higher-pitched sound profile. Despite these differences, both switches can provide a pleasant acoustic experience, although the Jammy is more about subtlety while the Xinhai (Heavy) aims for a sharper clarity.
Regarding feel, the Jammy switch is characterized by a medium weight that allows for a balanced typing experience, offering a nice blend of resistance and ease when pressing the keys. This makes it an excellent option for those who prefer a combination of comfort and tactile feedback. On the other hand, the Xinhai (Heavy) switch leans towards a more pronounced heft, making each keystroke feel more substantial. This heavier resistance may appeal to users who enjoy the sensation of a firmer press and a more deliberate typing action, promoting a feeling of precision and control.
In summary, both the HMX Jammy and HMX Xinhai (Heavy) linear switches have unique qualities that cater to different preferences. The Jammy excels with its muted sound and balanced feel, making it ideal for users seeking a gentle and satisfying typing experience. Meanwhile, the Xinhai (Heavy) offers a crisp sound with a heavier weight that appeals to those who enjoy a more pronounced and controlled typing action. Ultimately, your choice between these two switches will depend on whether you prioritize a softer auditory experience or a more resonant, tactile engagement with your keyboard.
Conclusion
To conclude, when choosing between the HMX Jammy and the HMX Xinhai (Heavy) linear switches, you'll want to consider your personal preferences for sound and feel, as well as the typing experience you seek. The Jammy switch, with its softer nylon housing, delivers a muted and deeply satisfying typing experience, making it an excellent choice if you prefer a more subtle sound and a plush feel during long typing sessions. Its medium bottom-out force of 63 grams strikes a balance that many find comfortable without causing strain. On the other hand, the Xinhai (Heavy) switch, crafted with PA12 housing and a POM stem, offers a crisper and higher-pitched resonance, ideal for those who appreciate a snappier auditory feedback with each keystroke. If you enjoy a slightly heavier feel with the 62.5 grams of actuation force, this switch is perfect for precise typing and gives a sophisticated acoustic profile. Ultimately, if you prioritize a softer and more muted experience, go for the Jammy, while the Xinhai (Heavy) is your best bet if you seek a more distinct sound and enhanced tactile feedback.
