HMX Jammy vs. Gazzew U4Tx
An in-depth look at the HMX Jammy and the Gazzew U4Tx switches—which one is the best fit for you?
Overview
When it comes to choosing between mechanical keyboard switches, the decision often comes down to personal preference and typing style. On one hand, the HMX Jammy, a linear switch, offers a softer and glittery nylon housing that provides a muted yet deeply satisfying typing experience. This switch is best for those who prefer a smoother keystroke without any tactile feedback. On the other hand, the Gazzew U4Tx, a tactile switch, combines the best of both worlds with a cleaner, refined sound profile. With a satisfying tactile bump and a mix of deep "thock" and quiet typing, the U4Tx is perfect for those who enjoy an acoustically pleasing and tactile typing experience. 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 HMX Jammy and the Gazzew U4Tx both aim to provide a deep and full sound profile for typing. The Jammy utilizes Nylon for both its top and bottom housings, which is known for its softer plastic composition that absorbs more sound, resulting in a duller and rounder sound. On the other hand, the U4Tx boasts a proprietary Gazzew blend for its top and bottom housings, also designed for a rich and deep sound profile due to its softness. Both switches aim to create a satisfying typing experience with their choice of housing materials, although the specific blend in the U4Tx may provide a unique sound compared to the classic Nylon of the Jammy.
While the top and bottom housings of the Jammy and U4Tx both aim to deliver deep and full sound profiles for typing enthusiasts, the specific composition of their materials may offer slight differences in sound and feel. The Jammy's Nylon top housing is known for creating a deeper and fuller sound when pressing down on a key, while the Gazzew blend top housing of the U4Tx is said to provide a rich and deep sound when releasing the key. This subtle distinction in sound impact showcases how the choice of housing material can influence the overall typing experience with these switches.
Despite the differences in their proprietary blend and classic Nylon materials, both the HMX Jammy and the Gazzew U4Tx ultimately aim to enhance the sound quality and tactile feel of typing switches. The softer plastic composition of Nylon in the Jammy's housing materials absorbs more sound, creating a rounder and duller sound profile, while the Gazzew blend in the U4Tx promises a rich and deep sound experience. Whether you prefer the classic feel of Nylon or the unique blend of the U4Tx, both switches strive to provide a satisfying typing experience through their housing materials.
Weight
In comparing the actuation force and bottom out force of the HMX Jammy linear switch and the Gazzew U4Tx tactile switch, it is clear that both switches have similar bottom out forces, with the Jammy being slightly heavier at 63 grams compared to the U4Tx's 62.5 grams. However, the Jammy has a lighter actuation force of 57 grams, while the actuation force of the U4Tx is unknown. The lighter actuation force of the Jammy may make it more suitable for those who prefer a lighter typing experience for longer periods of time, while the U4Tx's heavier bottom out force may appeal to those looking for a more substantial typing feel. Ultimately, the choice between the two switches will depend on personal preference for actuation force and bottom out force.
Travel distance
The HMX Jammy linear switch has a travel distance of 3.7 mm, while the Gazzew U4Tx tactile switch has a slightly shorter travel distance of 3.6 mm. Both switches fall into the category of shorter travel distances which are preferred by gamers for faster response times. However, the slight difference in travel distance between the two switches may not significantly impact the overall feel of typing or gaming. Ultimately, choosing between the two switches will depend on personal preference for a slightly shorter travel distance with the U4Tx or a slightly longer travel distance with the Jammy.

Typing experience
When it comes to sound, the HMX Jammy linear switch is best known for its softer and more muted typing experience, resulting in a deeply satisfying sound profile. On the other hand, the Gazzew U4Tx tactile switch offers a unique combination of a deep, resonant "thock" when bottoming out and a whisper-quiet sound when topping out. The U4Tx provides a sharper, more tactile bump with each press, creating a luxurious typing experience. While the Jammy switches offer a more subdued sound, the U4Tx switches deliver a cleaner and refined acoustically pleasing experience, making them stand out in terms of sound quality.
In terms of feel, the HMX Jammy linear switch is known for its medium-weight feel and offers a typing experience that is both smooth and satisfying. Meanwhile, the Gazzew U4Tx tactile switch provides a sharp tactile bump with each keypress, offering a high feedback intensity that is distinctly felt. The U4Tx switches provide a more pronounced tactile response, giving typists a more tactile and responsive feel compared to the smoother typing experience of the Jammy switches.
Overall, when comparing the HMX Jammy linear switch and the Gazzew U4Tx tactile switch, it is evident that they offer different subjective qualities in terms of sound and feel. The Jammy switches provide a softer and more muted typing experience with medium-weight feel, while the U4Tx switches offer a cleaner and refined sound profile with a sharper tactile bump for a more pronounced tactile feedback. Choosing between the two switches ultimately depends on personal preferences for sound and feel, as both switches have their own unique qualities that cater to different typing preferences.
Conclusion
To sum up, if you are looking for a linear switch with a slightly higher bottom out force and a typing experience that is muted and deeply satisfying, the HMX Jammy switch would be a great choice for you. On the other hand, if you prefer a tactile switch with a slightly lower bottom out force, a cleaner sound profile with a mix of deep thock and whisper-quiet topping out, as well as a sharp and intense tactile bump, then the Gazzew U4Tx switch would be the perfect fit for you. Ultimately, your decision should be based on your preferences for typing feel, sound profile, and bottom out force when choosing between these two excellent switches.
