Gateron Box CJ vs. HMX Jammy

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

Overview

When it comes to choosing between mechanical keyboard switches, two popular options to consider are the Gateron Box CJ and the HMX Jammy, both linear switches but with unique features. The Gateron Box CJ is renowned for its swift characteristics, ideal for those seeking rapid response in their typing experience. Typists can expect higher-pitched clacks and an incredibly smooth push feel that glides effortlessly. On the other hand, the HMX Jammy stands out with its softer nylon housings and medium-weight design, providing a more muted and deeply satisfying typing experience. While the Box CJ is known for its clacky and neutral feel, the Jammy offers a different typing experience altogether. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials

In comparing the housing materials of the Gateron Box CJ and the HMX Jammy, it is clear that they both utilize nylon for their bottom housings. Nylon is known for producing a deeper and fuller sound profile when typing on switches made from this material. However, the Box CJ takes it a step further by also incorporating polycarbonate for its top housing. Polycarbonate is a stiffer plastic that leads to a sharper, higher-pitched, and crisper sound profile. This combination of materials in the Box CJ gives users a unique typing experience with a mix of deep and full sounds from the nylon bottom housing and sharp and clear sounds from the polycarbonate top housing.

On the other hand, the HMX Jammy sticks to using nylon for both its top and bottom housing materials. This results in a consistent deep and full sound profile when typing on the switches. While the Jammy may not have the sharpness or crispness that the polycarbonate top housing of the Box CJ provides, the nylon material does absorb more sound, creating a duller and rounder sound overall. This makes the HMX Jammy a solid option for those looking for a more muted typing experience without sacrificing the depth and fullness of the sound.

In terms of overall sound and feel, the housing materials of the Gateron Box CJ and the HMX Jammy contribute differently to the typing experience. The split between polycarbonate and nylon in the Box CJ allows for a mix of sharpness and depth, impacting both the bottom-out sound and the sound when releasing a key. In contrast, the consistent use of nylon in the Jammy results in a more uniform sound profile throughout the key press. Both switches offer a unique typing experience, with the Box CJ providing a sharper and crisper sound and the Jammy offering a deeper and fuller sound while maintaining a level of consistency. Ultimately, the choice between the two will come down to personal preference in sound and feel.

Weight

The Gateron Box CJ linear switch has a lighter actuation force of 45 grams compared to the HMX Jammy linear switch, which has an actuation force of 57 grams. However, when it comes to bottom out force, the Box CJ requires 57 grams compared to the Jammy's 63 grams. This means that the Box CJ provides a lighter typing experience overall, making it easier to type for longer periods without fatigue. In contrast, the Jammy offers a slightly heavier feel, giving users a more substantial typing experience. Both switches fall into the medium category in terms of overall force required, so users can expect similar results in terms of performance despite the slight differences in actuation and bottom out forces. Ultimately, the choice between the two switches will come down to personal preference for typing feel and weight preference.

Travel distance

The Gateron Box CJ linear switch has a travel distance of 4 mm, while the HMX Jammy linear switch has a travel distance of 3.7 mm. The Box CJ has a slightly longer travel distance compared to the Jammy, but both fall within the range of traditional travel distances for switches. Gamers may prefer the shorter travel distance of the Jammy for faster response times, while those who prefer a more deliberate key press may opt for the slightly longer travel distance of the Box CJ. Ultimately, the choice between the two switches will depend on individual preference for key feel and responsiveness.

Typing experience

When it comes to sound, the Gateron Box CJ linear switch is known for its clacky nature, producing sharp and snappy sounds that are crisp and bright, adding a percussive element to typing. On the other hand, the HMX Jammy linear switch does not have a specific sound description available, so it is uncertain how it compares in terms of acoustic characteristics. Depending on personal preference and the overall setup of the keyboard, the choice between the two switches will ultimately come down to the desired sound profile.

Moving on to feel, the Gateron Box CJ linear switch offers a mild typing experience that is gentle and approachable, falling within a safe, middle-ground zone in terms of tactile feedback. Typists can expect a smooth push feel that effortlessly glides under their fingertips, enhancing the overall typing experience. Conversely, there is no available description of the typing feel of the HMX Jammy linear switch, making it difficult to draw a direct comparison in this aspect.

Overall, the Gateron Box CJ and HMX Jammy linear switches offer unique qualities that cater to different preferences. If sound is a priority, the clacky nature of the Box CJ may be more appealing, while the lack of a specific sound description for the Jammy switch leaves it open to interpretation. In terms of feel, the smooth and mild experience of the Box CJ sets it apart, although the feel of the Jammy switch remains unknown. Ultimately, both switches have their merits, and depending on individual preferences and requirements, either of them can provide a satisfying typing experience.

Conclusion

To sum up, when choosing between the Gateron Box CJ linear switch and the HMX Jammy linear switch, consider your preference for typing experience and sound profile. If you are looking for a switch with a rapid response, higher-pitched clacks, and smooth glide, the Box CJ may be the better option for you. On the other hand, if you prefer a typing experience that is muted and deeply satisfying, with a softer feel and glittery nylon housings, the Jammy switch may be more suitable. Ultimately, your decision should be based on your personal preference for typing feel and sound characteristics.
