HMX SU vs. Gazzew U4Tx RGB

Overview

When it comes to mechanical keyboard switches, the choice often boils down to personal preference in terms of feel, sound, and typing experience. The HMX SU is a linear switch, characterized by its full PA12 housing and T5 stem, which delivers a subtle yet relatively deep sound profile that many typists appreciate for its smooth and uninterrupted keypresses. This makes the SU an excellent choice for gamers and typists who prefer a quieter experience without tactile interruptions. On the other hand, the Gazzew U4Tx RGB switch offers a tactile sensation and an enticing auditory signature, combining the deep "thock" of U4T bottoming out with the quiet stealth of U4 topping out, creating a luxurious typing experience enriched by a pronounced tactile bump. This switch is ideal for those who enjoy feedback during their typing and prefer a more expressive sound profile. Both switches cater to specific needs and preferences: the HMX SU for a seamless and tranquil experience, and the Gazzew U4Tx RGB for a tactile thrill. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials

When comparing the housing materials of the HMX SU and the Gazzew U4Tx RGB switches, a notable similarity emerges: both utilize materials designed to enhance the auditory experience of typing. The HMX SU employs nylon for both its top and bottom housings, a classic choice that boasts a soft structure which aids in producing a deeper and fuller sound profile. This softness allows nylon to absorb sound, contributing to a duller and rounder sound signature, which typists often find appealing for its warmth. On the other hand, the U4Tx RGB features a proprietary blend of plastics, often referred to as "boba plastic." Despite being a different formulation, this material shares a similar softness characteristic with nylon, thereby offering a rich and deep sound profile as well.

Both switches deliver a satisfying auditory feedback experience, but the way each material impacts the sound and feel differs slightly based on their unique properties. While the nylon of the HMX SU consistently provides a cushioned typing experience, the Gazzew U4Tx RGB’s proprietary blend can be expected to create a comparable auditory resonance. Importantly, the impact of each housing material extends to the sound produced during different phases of pressing the key: the bottom housing primarily influences the bottom-out sound, while the top housing affects the release sound. This means that while typing on either switch, the overall sound will still be pleasingly rich and deep, albeit with slight variances depending on the specific housing used.

When considering usage in practical typing scenarios, the tonal character may vary due to the different compositions. However, users can expect comparable sonic results despite the differences in material. Both switches are engineered to create auditory experiences that resonate well with typists seeking deeper timbres in their typing sounds. Thus, regardless of whether it's the classic nylon or the innovative Gazzew blend, both switches capitalize on the fundamentals of sound absorption and material softness to create a fulfilling typing experience. Ultimately, each housing contributes uniquely to the sound profile, but the essential goal of providing a satisfying auditory feedback loop remains consistent across both switch designs.

Weight

When comparing the HMX SU linear switch and the Gazzew U4Tx RGB tactile switch, there are notable differences in their actuation and bottom out forces. The SU switch features a light actuation force of 45 grams and a bottom out force of 50 grams, making it ideal for users who prefer a lighter touch that accommodates long typing sessions or extended gaming periods. In contrast, the U4Tx RGB switch has an unknown actuation force but a heavier bottom out force of 65 grams, categorizing it as medium-heavy. This suggests that while the actuation force for the U4Tx is unspecified, its bottom out force significantly exceeds that of the HMX SU, providing a more substantial feel for those who appreciate a stronger push when typing. Therefore, the HMX SU can be considered the lighter option overall, while the Gazzew U4Tx RGB would cater to users seeking more resistance in their keystrokes.

Travel distance

Both the HMX SU linear switch and the Gazzew U4Tx RGB tactile switch have an identical travel distance of 3.6 mm, which means that users will experience the same distance when pressing down on each switch. Since both switches exhibit the same travel distance, they will provide a similar tactile experience in terms of how deep the key presses feel. This similarity can enhance typing consistency for users who switch between different keyboards equipped with these switches, as they can expect the same responsiveness and feedback from each switch.

Typing experience

When comparing the sound profiles of the HMX SU linear switch and the Gazzew U4Tx RGB tactile switch, the SU is known for its subtle and relatively deep sound. This gentle auditory signature gives it a smooth typing experience, making it well-suited for environments where noise might be a concern. In contrast, the U4Tx RGB switch delivers a unique auditory experience characterized by the deep “thock” produced when bottoming out. This sound merges with the quieter, stealthier topping out, resulting in an overall refined sound profile. Although the SU leans towards a more muted tone, the U4Tx RGB excites with its nuanced auditory dynamics. Keep in mind that both switches' sounds can vary based on the keyboard they are mounted on and the keycap choice.

Regarding feel, the SU linear switch provides a smooth, uninterrupted travel with no tactile feedback, which allows for rapid key presses and a fluid typing experience. This is ideal for users who prefer a lighter touch and faster keystrokes without any resistance. On the other hand, the U4Tx RGB tactile switch boasts a sharp tactile bump, providing noticeable resistance at the actuation point. This tactile feedback enriches the typing experience, making it feel more engaging and luxurious for those who enjoy a tactile sensation while typing. Therefore, while the SU offers a seamless, linear feel, the U4Tx RGB engages typists with its tactile response, catering to different preferences in tactile feedback.

In summary, the HMX SU linear switch and the Gazzew U4Tx RGB tactile switch present distinct auditory and tactile experiences. The SU's subtle, deeper sound profile and smooth linear feel cater to those seeking serenity and responsiveness in their typing. Conversely, the U4Tx RGB delights with its refined sound that ranges from a deep thock to a quieter top-out, paired with a satisfying tactile bump for an enriched typing experience. Ultimately, your choice between these two options will depend on whether you prioritize auditory nuances and tactile feedback or prefer a smoother, quieter typing experience.

Conclusion

To conclude, your choice between the HMX SU linear switch and the Gazzew U4Tx RGB tactile switch should depend on your specific preferences and typing needs. If you prefer a lighter touch with a smooth travel feel, the HMX SU is an excellent choice. With its 50-gram bottom out force, it provides a gentle yet satisfying response, making it great for long typing sessions, gaming, or when you desire a quieter and more subtle typing experience. The deeper sound profile adds to a serene atmosphere that may be ideal in shared spaces. On the other hand, if you appreciate a bit more resistance and enjoy a noticeable tactile feedback, the Gazzew U4Tx RGB switch is built for you. The 65-gram bottom out force combined with its sharp tactile bump offers a more engaging feel, making it suited for typists who enjoy the sensation of a switch that communicates your keystrokes effectively. The unique “thock” sound it produces gives an auditory satisfaction that many enthusiasts treasure. Ultimately, your decision should be guided by whether you favor the smoothness and lightness of the HMX SU or the tactile depth and feedback of the Gazzew U4Tx RGB, ensuring that your keyboard truly matches your typing style and environment.
