HMX FJ400 vs. Akko V3 Piano Pro
An in-depth look at the HMX FJ400 and the Akko V3 Piano Pro switches—which one is the best fit for you?
Overview
When considering mechanical keyboard switches, the HMX FJ400 and the Akko V3 Piano Pro stand out as intriguing options within the realm of linear switches. The FJ400, known for its balanced sound profile, strikes a harmonious middle ground in the HMX Film switch lineup, making it an appealing choice for users seeking a versatile typing experience without overpowering noise. In contrast, the Akko V3 Piano Pro boasts a unique long pole design, which contributes to its snappy sound signature, offering a lively and crisp auditory feedback with every keystroke. While both switches provide smooth actuation, the FJ400 caters to those who prefer a more muted sound, while the Piano Pro actively engages typists with its resonant and lively character. Ultimately, choosing between these two linear switches depends on individual preferences for sound and tactile experience; 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 FJ400 and the Akko V3 Piano Pro, it is notable that both switches utilize nylon for their bottom housing, contributing to a similar sound profile. The FJ400’s nylon bottom housing is specifically praised for its ability to absorb sound and create a deeper, fuller auditory experience, a characteristic shared with the V3 Piano Pro. This shared material choice means that users of both switches can expect a muted and rounded sound when typing, giving each keystroke a satisfying quality that's less prone to harshness. Therefore, despite the differences in their top housing materials, both designs tend to deliver a comparable auditory experience at the bottom-out stage of the keystrokes.
In contrast to their bottom housings, the FJ400 features a POM top housing, while the V3 Piano Pro opts for nylon. POM, or polyoxymethylene, is known for having a harder and more rigid structure compared to nylon, which impacts the sound profile produced during key release. The POM top housing of the FJ400 is said to create an incredibly unique sound that is deeper yet more muted, as opposed to the softer nylon found in the V3 Piano Pro, which is expected to yield a similar depth but potentially with a slightly brighter and more resonant quality. The difference in materials implies that while the bottom-out sound and feel may align closely, each switch will manifest its uniqueness through the varying top housing, influencing the overall auditory experience when keys are released.
Ultimately, the combination of a hard POM top housing in the HMX FJ400 and a nylon top housing in the Akko V3 Piano Pro exemplifies the interplay between material properties in achieving distinct sound aesthetics. Where the FJ400’s POM enhances the lower frequencies and adds to a more muted effect, the V3 Piano Pro’s nylon may allow for a broader spectrum of sound dynamics. For users, this means that typing experiences can vary not only in weight and feel but also in the subtleties of sound during actuation and release. The contrasting yet complementary housing materials encapsulate how sound profile characteristics can be tailored, making both switches appealing for different preferences while still delivering a shared foundational experience owing to their nylon bottom housings.
Weight
When comparing the HMX FJ400 linear switch and the Akko V3 Piano Pro linear switch, there are notable differences in both actuation force and bottom out force. The FJ400 features an actuation force of 50 grams and a bottom out force of 58 grams, making it a medium-weight option. In contrast, the V3 Piano Pro has a lighter actuation force of 45 grams and a bottom out force of 55 grams, categorizing it as medium-light. This difference in force means that users who prefer a lighter touch for prolonged typing sessions or gaming might find the V3 Piano Pro more comfortable, while those who appreciate a more substantial feel would likely lean towards the FJ400. Overall, the FJ400 is the heavier switch, making it potentially better for those who favor a stronger push feel, while the V3 Piano Pro's lighter weight caters well to users seeking ease during extended use.
Travel distance
The HMX FJ400 linear switch features a travel distance of 3.8 mm, making it the longer option when compared to the Akko V3 Piano Pro linear switch, which has a travel distance of 3.5 mm. This difference of 0.3 mm may seem minimal, but it can significantly impact the feel and responsiveness of each switch. Gamers often gravitate towards shorter travel distances like that of the V3 Piano Pro for quicker actuation and faster response times, while some users might prefer the deeper travel of the FJ400 for a more substantial typing experience. Ultimately, if you value a snappier feel, the V3 Piano Pro may be the better choice, whereas the FJ400 could cater to those desiring a more pronounced key press.

Typing experience
In terms of sound, the HMX FJ400 linear switch offers a balanced sound profile, making it a versatile choice that avoids extremes in auditory feedback. This middle-ground characteristic allows users to appreciate a satisfying typing experience without overwhelming noise. On the other hand, the Akko V3 Piano Pro linear switch excels in its lively sound signature, producing a clacky and resonant quality that is both crisp and bright. The snappy auditory feedback of the V3 truly enhances the typing experience, making each keystroke feel more engaging. However, it's important to note that the acoustic outcome can vary significantly depending on the keyboard build and keycap choices, so both switches have the potential to cater to different preferences.
When considering the feel of these switches, the FJ400 remains relatively undefined, leaving many details about its tactile characteristics unknown. However, the Akko V3 Piano Pro brings a rich tactile experience to the table, described as bouncy, creamy, polished, and silky. Users can expect a spring-like sensation with a rebound effect, providing an elastic feedback that enhances typing engagement. The creamy and polished attributes make for a refined and smooth typing experience, reducing friction and allowing fingers to glide effortlessly across the keys. This smoothness can significantly elevate usability, particularly during prolonged typing sessions.
In conclusion, while the HMX FJ400 delivers a balanced sound profile and has a somewhat undefined tactile quality, the Akko V3 Piano Pro shines with its snappy and crisp auditory feedback along with a richly textured feel that is both bouncy and silky. If you're seeking a lively and engaging typing experience, the V3 is likely the more exhilarating option. However, if you prefer a subtle yet versatile auditory feedback, the FJ400 will adequately meet those needs. Ultimately, the choice between these two switches will hinge on personal preferences regarding sound and tactile feel, but both can be enjoyable depending on your specific setup and upgrading path.
Conclusion
In conclusion, your choice between the HMX FJ400 and the Akko V3 Piano Pro linear switch should ultimately depend on your typing preferences and the experience you seek. If you’re looking for a more balanced and muted sound profile with a slightly firmer feel, the FJ400's bottom-out force of 58 grams makes it a suitable option. It's ideal for those who may be concerned about noise levels or prefer a setup that won't be overly distracting in a shared workspace. On the other hand, if you desire a lively and engaging auditory feedback when typing, the Akko V3 Piano Pro, with its clacky and resonant characteristics, will provide a more crisp and vibrant experience. The medium-light force of 55 grams paired with its bouncy and creamy feel offers a fun, dynamic typing sensation that is perfect for enthusiasts who relish a feedback-rich environment. Ultimately, your decision should reflect whether you prioritize sound dampening and a balanced keystroke or a more responsive and acoustically stimulating typing experience.
