HMX 1989 vs. KTT Sea Salt Lemon

An in-depth look at the HMX 1989 and the KTT Sea Salt Lemon switches—which one is the best fit for you?

Overview

When it comes to selecting the perfect mechanical keyboard switch, the HMX 1989 and KTT Sea Salt Lemon offer two distinct yet appealing options for those who appreciate a linear typing experience. The HMX 1989, renowned as the deepest and thockiest switch in the HMX Film series, delivers a satisfying resonance that enhances the tactile enjoyment of each keystroke. In contrast, the KTT Sea Salt Lemon shines with its progressive spring design and KTT's signature dry-lube treatment, ensuring an exceptionally smooth typing experience that feels almost buttery under the fingers. While the HMX 1989 may appeal to those who prioritize deep sound and pronounced thock, the Sea Salt Lemon caters to users who desire a subtler, low-pitched response combined with a neutral and mild acoustical profile. However, let's dive in a bit deeper beyond generalities so you can best decide on the switch that suits your unique typing preferences.

Housing materials

The HMX 1989 and the KTT Sea Salt Lemon share remarkable similarities in their construction, specifically in terms of their top housing material. Both switches utilize polycarbonate for the top housing, leading to a sound profile that is notably sharp, high-pitched, and crisp. This is attributed to polycarbonate's properties as a stiffer plastic, which enhances sound clarity and resonance. Furthermore, both switches leverage the translucency of polycarbonate to optimize RGB lighting effects, allowing for vibrant illumination that showcases the internal components. As a result, users can expect a visually striking appearance alongside a brilliant auditory experience from either switch.

On the other hand, the bottom housings of both the HMX 1989 and KTT Sea Salt Lemon are crafted from nylon, which contrasts with the polycarbonate used in the tops. This decision to use nylon results in a distinctly different sound profile; switches featuring nylon in the bottom housing provide a deeper, fuller sound due to the material's softer nature. Nylon helps absorb sound, leading to a more muted, rounder auditory feel compared to the clarity of the polycarbonate tops. Hence, while the top switches deliver a crisp sound upon release, the bottom housings enrich the typing experience with a more substantial feel and sound when a key is pressed down.

When considering the overall performance of these switches, the combination of nylon bottom and polycarbonate top in both models offers a complementary blend of sound characteristics. The polycarbonate elevates the high frequencies, making key release a bright event, while the nylon enriches the lower frequencies, resulting in a well-rounded typing experience. Because both switches share these material components, users can expect similar results in terms of sound and aesthetic appeal when comparing the two. In essence, the HMX 1989 and KTT Sea Salt Lemon embody a harmonious interplay of materials that yield consistent auditory and tactile feedback, regardless of individual design variations.

Weight

When comparing the HMX 1989 linear switch and the KTT Sea Salt Lemon linear switch, it’s interesting to note that both switches feature the same actuation force of 45 grams and a bottom out force of 53 grams, categorizing them as medium-light options. This similarity in force specifications means that users can expect comparable results in terms of typing and gaming experiences, as both switches will require the same amount of force to register a keystroke, and they will bottom out at the same pressure. Consequently, those who prefer lighter switches for extended periods of typing or long gaming sessions will find both options equally suitable. Overall, neither switch is heavier than the other, making them ideal choices for individuals seeking a balanced typing experience without the strain of heavier actuation.

Travel distance

Both the HMX 1989 linear switch and the KTT Sea Salt Lemon linear switch feature an identical travel distance of 4 mm, meaning users will experience the same distance when pressing down on the keys for both switches. This similarity in travel distance results in comparable tactile feedback and key press experience, making them both suitable options for those who prefer a consistent linear feel. Since both switches have the same travel distance, users can expect identical performance in terms of key actuation and responsiveness across the two options.

Typing experience

In terms of sound, the HMX 1989 linear switch is renowned for its deep, thocky acoustics, likely providing a satisfying resonance that enhances the typing experience. In contrast, the KTT Sea Salt Lemon produces a low-pitched sound, which gives it a bass-heavy and mellow quality, complemented by a neutral sound profile. This makes the Sea Salt Lemon suitable for various settings, from quiet home environments to bustling workplaces. While the 1989 excels in creating a signature thock that some users may prefer for aesthetics, the Sea Salt Lemon's sound profile is more versatile and adaptable to different situations, reflecting a broader range of preferences in sound.

When it comes to feel, the HMX 1989's attributes aren't explicitly mentioned, but its reputation for being the deepest of the HMX Film switch series implies a genuinely engaging typing experience that likely balances firmness and comfort. The KTT Sea Salt Lemon, conversely, is characterized by its mild feel, which provides a gentle typing experience that is approachable and user-friendly. This means that while the 1989 may offer a more pronounced tactile interaction, the Sea Salt Lemon ensures a smooth and fluid action without any jarring sensations. Both switches cater to different expectations, with the Sea Salt Lemon leaning towards accessibility, while the 1989 may appeal to enthusiasts looking for a deeper connection to each keystroke.

In conclusion, the HMX 1989 and KTT Sea Salt Lemon linear switches present distinct qualities that cater to different preferences among keyboard enthusiasts. The 1989 stands out with a deeply resonant sound and likely a more engaging feel, making it ideal for those who enjoy a tactile and auditory connection while typing. On the other hand, the Sea Salt Lemon emphasizes a buttery smooth experience with its low-pitched, neutral sound profile and mild feel, appealing to users seeking comfort and adaptability. Ultimately, both switches deliver excellent performance, but your choice will depend on whether you prefer a vibrant sound and feel or a smooth and versatile experience.

Conclusion

To sum up, when deciding between the HMX 1989 linear switch and the KTT Sea Salt Lemon linear switch, consider your personal preference for sound and feel in relation to your keyboard usage. If you appreciate a deeper, thockier sound and a robust typing experience, the HMX 1989 might be the right choice for your gaming sessions or if you want a switch that gives a tactile response without being overly pronounced. On the other hand, if you prefer a smooth and buttery typing experience that maintains a low-pitched, mellow sound profile, the KTT Sea Salt Lemon is ideal for everyday typing tasks, whether you’re working from home or in an office. Its mild characteristics make it approachable for both beginners and seasoned typists alike, offering a balanced performance that suits a variety of environments. Ultimately, your choice should hinge on your specific use case, sound preference, and tactile feedback, ensuring that your keyboard feels just right for the way you work and play.
