HMX Poro vs. KTT Purple Star
An in-depth look at the HMX Poro and the KTT Purple Star switches—which one is the best fit for you?
Overview
When it comes to choosing the right mechanical keyboard switch, both the HMX Poro and KTT Purple Star linear switches offer unique experiences that cater to different typing preferences. The HMX Poro is renowned for its ultra-smooth keystrokes and poppy, clacky sound profile, thanks to its meticulous lubrication and light actuation force, making it an appealing option for those who enjoy auditory feedback and a tactile sensation while typing. In contrast, the KTT Purple Star switches provide a buttery smooth typing experience due to their all-POM construction and a neutral sound signature, catering perfectly to light typists with their 45g bottom-out force that emphasizes ease and comfort. While the Poro excels in delivering a lively and engaging sound atmosphere, the Purple Star prioritizes a serene and effortless keystroke 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 HMX Poro and KTT Purple Star switches showcase contrasting materials in their construction, which contribute to their unique sound characteristics. The Poro employs a nylon top and bottom housing, which is recognized for its softer texture and sound absorption qualities. This results in a deeper and fuller sound profile that is described as duller and rounder due to nylon's ability to dampen sound. The uniformity of the Poro's nylon materials throughout the switch can lead to a cohesive auditory experience when typing. In particular, the sound and feel of each keystroke can be attributed to the nature of the nylon housing, ultimately creating a warm and intimate sound signature.
In contrast, the KTT Purple Star utilizes POM (polyoxymethylene) for both its top and bottom housings, known for producing a more distinct and muted sound profile. POM is a stiffer plastic compared to nylon, which yields a unique sound when the key is pressed and released. While it still provides a deeper sound akin to the Poro, the focus is on a clearer and cleaner auditory feedback that may resonate differently with users. Because the top and bottom housings are the same material, the sound profile remains consistent throughout the keystroke, offering a smooth transition from bottom-out to release without the tonal variance that might arise from the use of different materials.
Despite their differences, the overall sound profiles of the HMX Poro and KTT Purple Star can converge in the sense that both switches provide a deeper, muted sound. The distinct characteristics of each housing material influence how a key feels under the fingers and how sound is produced during use. Users can expect a satisfying experience from both switches, but those leaning towards a rounder and warmer sound might favor the nylon of the Poro, while those preferring a slightly more defined, muted sound may gravitate towards the POM of the Purple Star. Both switches ultimately cater to different preferences, allowing enthusiasts to choose the one that aligns best with their desired typing experience.
Weight
When comparing the HMX Poro linear switch and the KTT Purple Star linear switch, we find some interesting similarities and subtle differences in their force characteristics. Both switches have a light feel, making them suitable for extended typing sessions. The Poro has an actuation force of 45 grams, while the Purple Star features a slightly lighter actuation force at 43 grams. This difference means that the Purple Star is marginally easier to press, potentially appealing to users who prefer minimal resistance during typing. Both switches, however, share the same bottom out force of 50 grams, indicating that they provide a similar resistance when fully pressed down, which can add to a consistent typing experience across either option. Ultimately, if you're looking for a lighter switch, the Purple Star may be the better choice due to its lower actuation force, while both maintain a similar bottom out experience.
Travel distance
When comparing the travel distances of the HMX Poro linear switch and the KTT Purple Star linear switch, it is clear that the Poro features a travel distance of 3.7 mm, making it the longer option, while the Purple Star has a slightly shorter travel distance of 3.5 mm. This difference, although only 0.2 mm, can influence the overall feel and responsiveness of each switch. For gamers who favor faster response times, the KTT Purple Star's shorter travel distance may provide a more immediate action, which can be advantageous in competitive scenarios. Conversely, the HMX Poro, with its longer travel distance, might be better suited for those who appreciate a more substantial keypress experience, offering a deeper feel that can enhance typing satisfaction. Thus, the choice between the two switches ultimately hinges on personal preference regarding depth and responsiveness during use.

Typing experience
In terms of sound, the HMX Poro linear switches are known for their satisfyingly poppy and clacky sound profile, providing an engaging auditory experience that many typists find enjoyable. This lively sound can be a result of the ultra-light actuation force, which enhances the acoustic feedback during each keystroke. On the other hand, the KTT Purple Star linear switches are characterized by a low-pitched, neutral sound signature. This low-pitched tone tends to be bass-heavy and mellow, producing a quieter and more subdued typing sound compared to the Poro. The sound experience from both switches varies, with the Poro offering a more dynamic auditory feedback while the Purple Star provides a more laid-back auditory environment.
When it comes to feel, the HMX Poro linear switches stand out for their silky smooth keystrokes, meticulously lubricated to ensure a seamless typing experience. This attention to the glide provides a very fluid sensation, perfect for those who enjoy effortless typing motions. In contrast, the KTT Purple Star switches are mild in character, offering a gentle typing experience that straddles a safe middle ground. They feature easy-to-press qualities, requiring minimal force to activate, which ensures that even long typing sessions remain comfortable and fatigue-free. While the Poro emphasizes a smooth glide, the Purple Star focuses on a light, unassisted typing experience that any user can appreciate.
In summary, while both switches cater to light typists and have their unique characteristics, the HMX Poro linear switches offer a more pronounced sound profile along with an exceptionally smooth feel, whereas the KTT Purple Star linear switches provide a quieter, low-pitched sound combined with a gentle typing experience. Therefore, if you prefer a lively sound and a silky glide, the Poro would likely be your switch of choice. Conversely, for a more subdued auditory experience without sacrificing comfort, the Purple Star stands out as an excellent option. Both switches promise comfortable typing, but your preference for sound and feel will guide your ultimate decision.
Conclusion
To conclude, your choice between the HMX Poro linear switch and the KTT Purple Star linear switch ultimately depends on your personal typing preferences and the experience you seek. If you enjoy a slightly more tactile feedback and a satisfyingly poppy sound profile, the HMX Poro might be your ideal switch. Its silky smooth keystrokes, expertly lubricated for an effortless glide, can elevate your typing experience, especially if you appreciate switches that provide a more pronounced sensation and acoustic feedback. However, if you're looking for a smoother, quieter experience that caters to lighter types of typing, the KTT Purple Star is an excellent choice. With its all-POM construction and low-pitched sound signature, it offers a more gentle and mellow typing environment, making it suitable for those who prefer a softer touch and want to minimize finger fatigue during extended use. In essence, if comfort and a neutral sound are paramount for you, the Purple Star’s easy-to-press feel will likely suit your needs better. So, reflect on how you type and what you enjoy most in your keyboard experience to make the best choice for yourself.
