HMX Deep Navy vs. HMX SU
An in-depth look at the HMX Deep Navy and the HMX SU switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, two standout options are the HMX Deep Navy and the HMX SU, both linear switches designed for smooth keystrokes but with distinct characteristics that cater to different preferences. The Deep Navy switch boasts a full nylon construction that not only enhances its durability but also delivers a rich and sharp sound profile, creating an engaging typing experience. Users who appreciate a tactile aural feedback along with silky smoothness in their keystrokes might find the Deep Navy particularly appealing. On the other hand, the HMX SU features a full PA12 housing and a T5 stem that offers a subtle, relatively deep sound profile, making it suitable for those who prefer a more understated auditory experience while typing. Each switch has its own unique charm and utility, which can greatly influence your overall typing or gaming experience. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
Both the HMX Deep Navy and the HMX SU utilize nylon for both their top and bottom housing components, which is a well-regarded material in the mechanical keyboard community. The fact that both switches feature nylon demonstrates a commitment to sound quality and tactile feedback, as nylon's softer composition tends to absorb sound more effectively than harder plastics. As a result, both variants are likely to produce a similar deeper and fuller sound profile that many users appreciate. The shared material choice not only contributes to the acoustic properties of the switches but also ensures a consistent typing experience across both models.
In terms of the impact on sound and feel, the nylon top and bottom housings play distinct roles in the overall performance of the switches. The bottom housing, being instrumental in defining the bottom-out sound and feel when a key is pressed, combines with the sonic characteristics imparted by the softer nylon material. Conversely, the top housing predominantly influences the sound produced when the key is released. Since both switches employ identical nylon materials for their housings, users can expect similar acoustic feedback during both the actuation and rebound stages of typing, ensuring that the experience is unified regardless of which model they choose.
Ultimately, the similarity in housing materials for both the HMX Deep Navy and the HMX SU translates into a predictable and cohesive user experience. Since both switches are constructed with the same nylon components, users will find that the distinctions in sound and feel are minimized, providing an almost indistinguishable typing experience. This consistency is particularly beneficial for users who prioritize uniformity in their keyboards, whether they choose the HMX Deep Navy or the HMX SU. The shared nylon composition not only fosters a deeper sound but also enhances the overall tactile feedback that both models deliver, thereby solidifying nylon as a universal choice for quality mechanical switches.
Weight
When comparing the HMX Deep Navy linear switch and the HMX SU linear switch, there are notable differences in both actuation and bottom out forces. The Deep Navy features a lighter actuation force of 40 grams compared to the SU's 45 grams, making it more suitable for those who prefer less resistance for prolonged typing or gaming sessions. Similarly, the bottom out force of the Deep Navy is 45 grams, which is also lighter than the SU's 50 grams. As a result, users seeking a more delicate touch and ease of use may gravitate toward the Deep Navy switch, whereas those who favor a stronger push feel will likely prefer the heavier SU switch. Overall, the Deep Navy offers a gentler typing experience, while the SU provides a more substantial tactile feedback with its heavier forces.
Travel distance
The HMX Deep Navy linear switch and the HMX SU linear switch both feature an identical travel distance of 3.6 mm, meaning that the distance each switch travels from the top to the bottom is the same. As a result, users can expect a similar tactile experience and actuation response with both switches, providing consistent performance when pressing down on a key. Thus, whether opting for the Deep Navy or the SU, the travel experience remains unchanged, delivering equal satisfaction in terms of feel and responsiveness.

Typing experience
In terms of sound, the HMX Deep Navy linear switch offers a pronounced and rich auditory experience, thanks to its full nylon construction. The sharp sound profile enhances the overall typing experience, providing a satisfying acoustic response with each keystroke. On the other hand, the HMX SU linear switch presents a more subtle but relatively deep sound profile, attributed to its PA12 housing. While both switches aim to create a pleasing sound environment, the Deep Navy leans towards a sharper and potentially louder experience, whereas the SU provides a more muted yet still gratifying auditory backdrop. It's essential to consider that the final sound produced can be influenced by the keyboard build, choice of board, and keycaps.
When it comes to feel, the Deep Navy switch is designed for silky smoothness, allowing for effortless key presses and an overall fluid typing experience. This smooth action can enhance comfort during prolonged use. In contrast, the SU switch, paired with its T5 stem, offers a similar smoothness but with potentially subtle differences in response that can affect tactile feedback. While both switches prioritize a seamless feel, users may find slight variations in how each responds to their typing style, with the Deep Navy providing a more refined sensation and the SU maintaining a dependable smoothness.
In summary, both the HMX Deep Navy and HMX SU linear switches deliver enjoyable typing experiences, albeit with distinct auditory characteristics and slight variations in feel. The Deep Navy's rich sound and silky smoothness stand out for those who enjoy a more pronounced acoustic response, while the SU favors a deeper, subtler auditory signature paired with reliable smoothness. Depending on your preferences in sound and tactile feedback, either switch can provide an exceptional mechanical typing experience.
Conclusion
To conclude, when deciding between the HMX Deep Navy linear switch and the HMX SU linear switch, you should consider your preferences for sound, feel, and keypress force. If you are looking for a more pronounced audio experience, the Deep Navy switch, known for its rich and sharp sound profile, would likely enhance your enjoyment, especially if you're someone who appreciates the auditory feedback of your keyboard. With its lighter bottom-out force of 45 grams, it also offers a softer keystroke that may be appealing to those who type lightly or prefer quick, effortless typing. On the other hand, if you prefer a subtle yet deeper sound profile and a slightly firmer feel with a bottom-out force of 50 grams, the SU switch might be the better option for your typing needs. The PA12 housing and T5 stem provide a satisfying tactile experience that can enhance your overall comfort during long typing sessions. Ultimately, selecting the right switch depends on whether you value a sharper sound and lighter touch or a deeper audio experience and slightly more resistance in your keystrokes.
