Keygeek Keylin vs. HMX Xinhai (Heavy)
An in-depth look at the Keygeek Keylin and the HMX Xinhai (Heavy) switches—which one is the best fit for you?
Overview
When exploring the world of mechanical keyboard switches, two notable options stand out: the Keygeek Keylin and the HMX Xinhai (Heavy), both of which fall into the linear switch category. The Keylin is renowned for its use of new molds, which result in a premium typing experience characterized by rich acoustics and exceptional smoothness, making it an excellent choice for those who prioritize a whisper-quiet yet satisfying keystroke. In contrast, the HMX Xinhai (Heavy) offers a heavier variant of the classic design, featuring a unique PA12 top housing that promotes a softer acoustic profile, paired with a POM stem that delivers a distinctively crisp and higher-pitched resonance. While the Keylin may appeal to users seeking a refined, smooth typing experience, the Xinhai (Heavy) provides an option for those inclined toward a burly feel complemented by sophisticated sound dynamics. However, let's dive in a bit deeper beyond generalities so you can best decide on the ideal switch for your typing needs.

Housing materials
When comparing the housing materials of the Keygeek Keylin and the HMX Xinhai (Heavy), it becomes immediately clear that both use nylon for both their top and bottom housings. Nylon is a well-established material in the keyboard switch industry due to its favorable acoustic properties. Both switches deliver a fuller and deeper sound profile, as nylon's softer composition significantly absorbs sound waves, contrasting with the harsher sounds produced by harder plastics. This similarity ensures that users will experience a rounded and muted sound when typing, contributing to a more pleasant auditory experience.
While both switches utilize nylon for their housings, the overall typing feedback may vary slightly based on the specific design and engineering of each switch. If we consider the bottom and top housing's impact separately, the Keylin's characteristics will deliver a robust bottom-out sound due to the nylon material's inherent dampening qualities. Likewise, the Xinhai (Heavy) will also provide a similar sound profile, with the top housing contributing to the sound emitted upon key release. As such, both switches ultimately achieve comparable results in sound quality, though slight variances may arise from their unique configurations.
Moreover, since both the Keygeek Keylin and the HMX Xinhai (Heavy) employ nylon in both housing components, users may find the switches overall quite similar in terms of tactile feel and sound dynamics. The softness and acoustic absorption properties of the nylon ensure that both switches will resonate similarly when pressed, making the bottom-out experience satisfying and muted. Consequently, while subtle variations may exist due to individual switch mechanics, the overarching characteristics of both the Keylin and the Xinhai (Heavy) switches, driven by their shared material, lead to a notably consistent and enjoyable typing experience.
Weight
When comparing the Keygeek Keylin linear switch and the HMX Xinhai (Heavy) linear switch, the differences in their actuation and bottom out forces highlight distinct usability preferences. The Keylin switch features a lighter actuation force of 38 grams and a bottom out force of 48 grams, making it more suitable for users who favor longer typing sessions without fatigue. In contrast, the Xinhai (Heavy) switch has a notably heavier actuation force of 55 grams and a bottom out force of 62.5 grams, appealing to those who prefer a more substantial and robust typing feel. These differences in actuation force indicate that while the Keylin is easier to trigger, requiring less effort, the Xinhai provides a firmer resistance, catering to users who enjoy a stronger push. Ultimately, the Keylin is the lighter option, while the Xinhai is the heavier choice, allowing users to select based on their typing preferences and the overall experience they desire.
Travel distance
When comparing the travel distances of the Keygeek Keylin linear switch and the HMX Xinhai (Heavy) linear switch, we find a slight difference that may influence user preference. The Keylin boasts a travel distance of 3.6 mm, making it the longer option, while the Xinhai (Heavy) has a travel distance of 3.4 mm, which is shorter. This distinction of 0.2 mm may seem minor, but it can affect the overall feel and responsiveness of the keypress. Gamers, who often favor shorter travel distances for quicker response times, might lean towards the Xinhai (Heavy) for a more agile experience. In contrast, those who appreciate a more pronounced depth and tactile feedback might prefer the Keylin. Ultimately, the choice between these two switches hinges on individual preferences regarding tactile feedback and responsiveness in keypresses.

Typing experience
The Keygeek Keylin linear switch is celebrated for its rich acoustics, delivering a sound profile that enhances the overall typing experience, though specific tonal qualities aren’t detailed. In contrast, the HMX Xinhai (Heavy) switch produces a distinctively crisp, higher-pitched resonance attributed to its PA12 top housing and POM stem, offering a softer acoustic profile. While both switches provide a satisfying auditory experience, their sound characteristics differ, with the Keylin leaning towards a fuller tone and the Xinhai excelling in a sharper, more refined sound. Of course, the final sound can vary significantly based on the keyboard's construction, including the choice of board and keycaps.
When it comes to feel, the Keylin linear switch is known for its exceptional smoothness, suggesting a seamless and enjoyable typing sensation that is likely to appeal to those who prefer a fluid keystroke. On the other hand, the Xinhai (Heavy) switch emphasizes a heavier actuation force, hinting at a more pronounced resistance during typing. This difference in feel can cater to varying preferences; some users might appreciate the lighter, more effortless Keylin, while others might prefer the tactile feedback and controlled engagement of the Xinhai (Heavy).
In summary, both the Keylin and Xinhai (Heavy) linear switches offer unique qualities that cater to different typing preferences. The Keylin's emphasis on smoothness and rich acoustics creates a premium experience, whereas the Xinhai (Heavy) provides a crisp sound with a heavier feel, appealing to users who enjoy a more robust tactile sensation. Depending on your priorities, whether it's sound quality or typing feel, each switch presents advantages that can lead you to an enjoyable mechanical keyboard experience.
Conclusion
To conclude, choosing between the Keygeek Keylin linear switch and the HMX Xinhai (Heavy) linear switch ultimately depends on your personal preferences and typing style. If you prefer a lighter touch and a smooth, premium feel, the Keylin switch will likely serve you well, especially for extended typing sessions or gaming, where less finger fatigue is desired. Its rich acoustics and exceptional smoothness make it a delightful choice for those who prioritize a satisfying and immersive typing experience. On the other hand, if you appreciate a firmer resistance and the clarity of a sharper acoustic profile, the Xinhai (Heavy) is an excellent option. Its heavier actuation force and unique materials provide a more robust and refined typing experience, ideal for those who enjoy a slightly more tactile feedback and a crisp sound. Ultimately, consider your typing habits and sound preferences when making your choice, as both switches offer distinct characteristics that can significantly impact your overall keyboard experience.
