Bsun Guyu vs. HMX Jammy
An in-depth look at the Bsun Guyu and the HMX Jammy switches—which one is the best fit for you?
Overview
The BSUN Guyu and HMX Jammy are two popular linear mechanical keyboard switches that offer unique characteristics for different typing experiences. The Guyu is praised for its all-POM housings that enhance acoustics and create a bright, crisp sound upon bottoming out, while the UPE stem provides super-smooth keystrokes for effortless typing sessions. On the other hand, the Jammy features softer nylon housings, resulting in a muted but deeply satisfying typing feel. While the Guyu is described as clacky, creamy, and polished, the Jammy's characteristics are yet to be categorized. Both switches have their own set of advantages and appeal to different preferences in typing sensation. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The housing materials of the Bsun Guyu and the HMX Jammy both bring unique qualities to the switches. The Guyu's POM top housing creates a deep and muted sound profile, while the Jammy's nylon top housing produces a fuller and rounder sound. Both materials have their own way of absorbing sound, with POM having a more muted effect and nylon creating a duller sound. However, they both contribute to a pleasing sound experience for the user, albeit with slightly different characteristics.
In terms of the bottom housing, the POM bottom housing of the Guyu and the nylon bottom housing of the Jammy also offer distinct advantages. The POM bottom housing of the Guyu contributes to a deeper sound profile, similar to its top housing. On the other hand, the nylon bottom housing of the Jammy adds to the fuller sound of the switch, enhancing the overall typing experience for the user. Despite these differences, both materials serve to create a unique sound and feel for each keyboard switch.
Overall, the top and bottom housings of the Bsun Guyu and the HMX Jammy play a crucial role in shaping the sound profile and typing experience of the switches. While the materials used may differ, they both aim to provide a satisfying typing experience for the user. Whether it's the deeper and muted sound of POM in the Guyu or the fuller and rounder sound of nylon in the Jammy, each housing material brings its own unique qualities to the switches. Ultimately, both keyboards offer a high-quality typing experience thanks to the carefully selected housing materials used in their construction.
Weight
The Bsun Guyu linear switch has a lighter actuation force of 45 grams compared to the HMX Jammy linear switch, which has a heavier actuation force of 57 grams. This means that the Guyu switch will require less force to trigger a keystroke, making it more suitable for those who prefer a lighter typing experience. In terms of bottom out force, the Guyu switch also has a lighter force of 50 grams compared to the Jammy switch's heavier force of 63 grams. This indicates that the Jammy switch will provide a more substantial typing experience when fully pressing down on the key. Overall, the Guyu switch is lighter in both actuation and bottom out forces compared to the Jammy switch. Those who prefer a lighter typing experience for longer periods of time may lean towards the Guyu switch, while those who prefer a stronger push feel may opt for the Jammy switch.
Travel distance
The Bsun Guyu linear switch has a travel distance of 3.6 mm, while the HMX Jammy linear switch has a travel distance of 3.7 mm. Both switches fall within the range of shorter travel distances, which are popular among gamers for their faster response times. However, the Jammy switch has a slightly longer travel distance, which may provide a slightly more substantial keypress feel compared to the Guyu switch. Ultimately, whether you prefer the shorter travel distance of the Guyu switch or the slightly longer travel distance of the Jammy switch will depend on your personal preference for keypress depth and responsiveness.

Typing experience
In terms of sound, the BSUN Guyu linear switch offers a clacky typing experience, producing a sharp and snappy sound when pressed, characterized by its crisp, bright, and percussive nature. On the other hand, the HMX Jammy linear switch, with its softer and glittery nylon housings, provides a more muted and deeply satisfying sound profile. While both switches offer unique auditory experiences, the Guyu's acoustics are enhanced by its POM housings and long pole stem, resulting in a distinctive sound signature that combines depth and clarity.
Moving on to the feel aspect, the BSUN Guyu linear switch is described as creamy, frictionless, polished, silky, and snappy, offering a smooth and buttery typing experience with minimal resistance and effortless key travel. These qualities result in an overall silky sensation when typing, akin to gliding your fingers effortlessly across the keys. In contrast, the specific feel descriptors for the HMX Jammy linear switch are currently unknown. Whether they provide a similar level of smoothness and responsiveness as the Guyu remains undisclosed.
Overall, the BSUN Guyu and HMX Jammy linear switches offer distinct subjective qualities in terms of sound and feel. The Guyu showcases a clacky sound profile and a creamy, frictionless, polished, silky, and snappy typing feel, making it a preferred choice for those seeking a unique acoustic and tactile experience. On the other hand, the Jammy's softer and glittery nylon housings suggest a different sound and feel compared to the Guyu, potentially appealing to users looking for a more muted typing experience. Ultimately, the decision between these two switches would depend on individual preferences for sound aesthetics and typing feel.
Conclusion
To sum up, when deciding between the BSUN Guyu linear switch and the HMX Jammy linear switch, consider the following factors. If you prioritize a unique auditory experience with a medium-weight switch that provides super-smooth keystrokes and resonant feedback, the Guyu might be the best choice for you. On the other hand, if you prefer a typing experience with softer and glittery nylon housings that offer a muted yet deeply satisfying feel, the Jammy switch could be more suitable for your needs. Ultimately, your decision should be based on your preference for sound, feel, and overall typing experience. Both switches offer their own unique characteristics, so choose wisely based on what matters most to you.
