Introduction

Back in April, I had the opportunity to review the Redragon K556 HE, my first Hall Effect keyboard. More recently, Redragon provided me with the EISA K686 HE for review, giving me the chance to see how a compact 98% Hall Effect keyboard compares to the full-size layouts I have used for years.

For the past seven months, my daily driver has been the Redragon K761, so moving to a smaller keyboard was a significant change. The first thing I noticed was the size difference. The K686 HE is approximately 2 inches narrower than my K761, giving it a noticeably smaller footprint while still retaining nearly all of the keys and functionality I use on a daily basis. Despite its smaller size, I did not gain any practical mouse space since I use the Redragon Drake Oath "Raina" glass mousepad, which already provides more than enough room for gaming. Instead, the benefit of the compact layout is a cleaner, less cluttered desk setup.

One small but thoughtful design choice I immediately appreciated was the placement of the USB-C port on the left side of the keyboard. The included right-angle cable works perfectly with this layout, making cable routing simple and helping maintain a clean appearance on my desk.

The K686 HE packs an impressive feature set that includes UltraMag magnetic switches, Rapid Trigger technology, 8K hyper-polling, a multifunction control knob, and multiple layers of sound dampening. Redragon positions the keyboard as a high-performance gaming board, but after spending time gaming, typing, and using it for everyday tasks, I found that its strengths extend beyond gaming alone. The switches feel smooth and responsive, the acoustics are pleasant, and the overall typing experience is enjoyable for extended periods of use. Redragon specifically advertises UltraMag magnetic switches, Rapid Trigger support, 8K polling, and integrated noise dampening on the K686 HE

As someone who has always used 100% keyboards, there has been a small adjustment period. I still occasionally find myself glancing down to locate certain keys, but that is more a matter of breaking years of muscle memory than a flaw with the keyboard itself. The transition to the 98% layout has been much easier than I expected.

In this review, I will take a closer look at the K686 HE's build quality, switches, typing experience, gaming performance, RGB lighting, software, and overall value to determine whether this compact Hall Effect keyboard is worth a place on your desk.

Switches

The Hall Effect switches on the Redragon EISA K686 HE are one of its standout features. They feel exceptionally smooth straight out of the box, with very little friction during keypresses. The keystrokes are consistent across the keyboard, providing a predictable and reliable typing experience.

For gaming, the switches offer quick response times and precise actuation, making movement, aiming, and rapid inputs feel effortless. Since Hall Effect switches rely on magnetic sensing rather than physical contacts, keypresses feel clean and consistent even during fast-paced gaming sessions.

For typing, the switches provide a smooth linear feel that allows fingers to glide from key to key without resistance. This results in a comfortable experience during long work or study sessions. The combination of smooth travel and stable keypresses gives the keyboard a more premium feel than many keyboards in its price range.

Stabilizers

The stabilizers are well executed and contribute significantly to the keyboard's overall feel. Larger keys such as the Spacebar, Enter, Backspace, and Shift feel stable with minimal side-to-side wobble. This helps create a more refined typing experience and prevents the larger keys from feeling loose or uneven.

Acoustically, the stabilizers are relatively well-tuned, producing a clean sound with little rattling. The spacebar in particular feels solid and controlled, which enhances both the sound profile and typing satisfaction. Combined with the keyboard's gasket-mounted design and internal dampening materials, the stabilizers help deliver a deeper and more consistent typing sound.

4: Typing Experience

The Redragon EISA K686 HE delivers a typing experience that feels surprisingly refined for its price point. From the first few keystrokes, the keyboard feels smooth, controlled, and comfortable. The Hall Effect switches glide effortlessly through their travel, requiring minimal force to actuate while maintaining a consistent feel across the entire board.

One of the keyboard's strongest qualities is its sense of stability. Each keypress feels solid and well-supported, with very little wobble. This creates a confident typing experience where keys feel precise rather than loose or shaky. Whether typing quickly or slowly, the keyboard maintains a consistent feel that helps improve accuracy and overall comfort.

The gasket-mounted design adds a slightly cushioned sensation when bottoming out. Instead of a harsh impact, keystrokes feel softer and more forgiving. This becomes especially noticeable during long writing sessions, where the keyboard remains comfortable and reduces finger fatigue compared to stiffer tray-mounted designs.

Another highlight is the keyboard's acoustics. The combination of internal dampening, well-tuned stabilizers, and smooth switches produces a deep, clean sound profile. The keyboard avoids excessive hollowness or metallic ping, giving each keystroke a satisfying and premium character. Larger keys such as the spacebar, Enter, and Backspace sound consistent with the rest of the board, which further enhances the typing experience.

For productivity tasks, the K686 HE feels fast and responsive, making it easy to maintain a steady typing rhythm. For gaming, the Hall Effect technology provides immediate and accurate input registration, allowing rapid key presses without sacrificing control.

5: Gaming Performance

 

The Redragon EISA K686 HE performs exceptionally well in gaming, largely thanks to its Hall Effect switch technology. Key presses feel fast, accurate, and highly responsive, allowing commands to register instantly during gameplay. This responsiveness is particularly noticeable in competitive titles where quick reactions and precise movement are important.

The keyboard's smooth switches make rapid inputs effortless, whether you are strafing in FPS games, executing combos in fighting games, or performing repeated actions in MOBAs and MMOs. Since the switches provide a consistent feel across the board, it is easy to build muscle memory and maintain accuracy during intense gaming sessions.

The stable construction also contributes to the gaming experience. Keys remain steady even during aggressive use, while the well-tuned stabilizers ensure larger keys such as Spacebar and Shift feel reliable and predictable. This consistency helps maintain confidence during fast-paced gameplay.

Wireless performance is also dependable for everyday gaming, while the wired connection provides the most stable experience for competitive play. The compact 98% layout keeps essential keys within easy reach while leaving more room for mouse movement, which many gamers will appreciate.

Another advantage is the keyboard's comfortable acoustics and typing feel. Long gaming sessions remain enjoyable because the switches are smooth, the sound profile is pleasant, and the gasket-mounted design helps soften keystrokes without feeling sluggish.

Gaming Verdict: The Redragon EISA K686 HE is an impressive gaming keyboard that combines responsive Hall Effect switches, smooth key feel, and a solid gasket-mounted design into a well-rounded package. Its fast and accurate input registration, stable keys, and comfortable acoustics make it equally suited for competitive and casual gaming. While there are more expensive Hall Effect keyboards on the market, the K686 HE delivers excellent performance and value, making it an easy recommendation for gamers looking to upgrade to magnetic switches without breaking the bank.

To make the review easier to read and navigate, I have divided it into clearly defined sections. This allows readers to quickly jump to the topics that matter most to them, whether that's gaming performance, typing experience, build quality, software features, RGB lighting, or advanced Hall Effect functionality.

If you're simply looking for a solid gaming keyboard, you can focus on the typing and gaming sections. If you're interested in getting the most out of the Hall Effect switches, the software and PRCS sections provide a deeper look into the advanced customization options available on the K686 HE.

No single keyboard is perfect for everyone, but by breaking each feature down individually, my goal is to help you determine whether the Redragon EISA K686 HE is the right fit for your needs, preferences, and gaming style.
