Verdict: The Redragon Devarajas K556 remains a reasonable budget mechanical keyboard for buyers who want a full-size layout, RGB lighting, an aluminum top plate, and replaceable switches without paying enthusiast prices. It is less appealing if you need wireless connectivity, premium keycaps, quiet acoustics, dedicated macro keys, or sophisticated remapping software.
The original K556 is a 104-key, wired keyboard with Outemu Brown or Red switches, a detachable USB-C cable, RGB backlighting, and a hot-swappable switch design. Redragon’s US store listed it at $59.99 when checked, although prices and stock—particularly for the Red switch version—can change.

What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Design and build quality
The K556 uses a floating-key design on a brushed, anodized aluminum top and side structure. The lower frame is plastic, so this is not an all-aluminum chassis, but the metal upper section gives the board more visual weight and rigidity than a basic plastic keyboard. At approximately 1.18 kg, it is substantial enough to stay planted during ordinary typing and gaming.
#1 Best Overall
- Aluminum Build That Won't Wobble - A tank-solid brushed aluminum board keeps every keystroke steady during intense sessions, unlike the flex you get from plastic-frame keyboards.
- Swap Switches Without Soldering, Comfortable Out of the Box - The upgraded socket accepts almost any 3-pin or 5-pin switch, and the stock Brown switches give a soft tactile bump for all-day typing comfort.
- Vibrant RGB for a True eSports Vibe - 20 preset lighting modes with adjustable brightness and flow speed give your desk the glow of a dedicated gaming rig.
- Full Anti-Ghosting, Wide System Compatibility - 104 keys register accurately during rapid combos, and plug-and-play wired connection works across Windows and Mac with no drivers required.
- Pro Software for Even Deeper Customization - Want to go beyond the onboard presets? The companion software lets you design custom RGB effects and program macros with your own keybindings.
The full-size 104-key layout includes a number pad and the usual navigation cluster. That makes it more practical for spreadsheets, data entry and office work than compact gaming keyboards. The trade-off is desk space: it is considerably wider than a tenkeyless or 75% board.
Independent observations from AnandTech’s 2021 review found the feet relatively small and the anti-slip arrangement imperfect. With the feet extended, the front portion could contact a softer wooden desk in an undesirable way. A desk mat can reduce friction and protect the surface. These observations come from a review sample and should not be treated as a guarantee that every later production batch is identical. See the AnandTech review for the original physical examination.
The cable is detachable and uses a USB-C connector at the keyboard. That describes the connector and cable arrangement; it does not imply wireless operation or any particular modern USB feature beyond the wired connection.
Switches and typing feel
The original review sample used Outemu Brown switches, while Redragon’s current listing also offers Outemu Red switches. The two choices suit different preferences:
- Brown: tactile, with a noticeable bump but no deliberately clicky mechanism. It is generally the safer choice for mixed typing and gaming.
- Red: linear, with a smooth keypress and no tactile bump. It tends to suit users who prefer uninterrupted movement for gaming or light-touch typing.
Neither option should automatically be called quiet. Noise depends on the switch, keycap, stabilizers, case resonance, desk surface and typing force. Browns can produce noise from the tactile switch and bottom-out, while Reds can still be loud when the keys hit the plate or case.
The keyboard’s full-size layout is familiar and productive, but the styling is less restrained than an office-oriented board. Redragon uses a futuristic legend design, and the glossy sides of the keycaps can reflect RGB light when viewed from an angle.
Rank #2
- Aluminum Build That Won't Wobble - A tank-solid brushed aluminum board keeps every keystroke steady during intense sessions, unlike the flex you get from plastic-frame keyboards.
- Switch Devices Without Re-Pairing, Zero Lag - Tri-mode connectivity jumps between USB-C, Bluetooth, and 2.4GHz wireless with near-wired responsiveness, so going wireless doesn't cost you speed.
- Swap Switches Without Soldering, Smooth and Quiet - Quiet linear switches give a clean, low-noise keystroke, and the upgraded socket accepts almost any 3-pin or 5-pin switch.
- Vibrant RGB for a True eSports Vibe - 20 preset lighting modes with adjustable brightness and flow speed give your desk the glow of a dedicated gaming rig.
- Pro Software for Even Deeper Customization - Want to go beyond the onboard presets? The companion software lets you design custom RGB effects and program macros with your own keybindings.
Keycaps, stabilizers and layout compatibility
The US version uses a standard full-size ANSI layout with a 6.25-unit spacebar. Its bottom row places an Fn key where some keyboards would have a second Windows key. That detail matters if you plan to install aftermarket keycaps: a standard-looking set may not include the correct bottom-row sizes.
Recommended Free Tools
The keycaps are ABS, not PBT. They are functional and allow the backlighting to show through, but they are not the premium, textured or particularly shine-resistant caps associated with more expensive enthusiast keyboards. Do not buy the K556 expecting double-shot PBT keycaps.
RGB lighting and onboard controls
Redragon advertises 16.8 million RGB colors and 18 lighting modes. Preset effects can be controlled from the keyboard, which is useful if you do not want to install software. The board also provides multimedia functions through its Fn layer, supports Windows-key locking and offers an interchangeable WASD/arrow-key function according to the manufacturer.
AnandTech found the lighting bright and crisp on its sample, with limited bleeding. The glossy keycaps could create distracting reflections from side angles, however. RGB quality is subjective and changes with ambient light, viewing angle and keycap condition.
Onboard controls are sufficient for changing effects and basic functions. Detailed per-key lighting, remapping and profiles require Redragon’s utility.

The K556 provides mechanical switches, anti-ghosting, non-conflict keys, RGB profiles and multimedia functions. Those features make it a perfectly usable gaming keyboard, but they do not establish a competitive advantage. The available review did not provide verified measurements for latency, polling behavior, debounce or scan rate, so claims about low latency or esports performance would be unsupported.
Rank #3
- Aluminum Build That Won't Wobble - A tank-solid brushed aluminum board keeps every keystroke steady during intense sessions, unlike the flex you get from plastic-frame keyboards.
- Swap Switches Without Soldering, Smooth and Quiet - The upgraded socket accepts almost any 3-pin or 5-pin switch, and the stock Red linear switches keep late-night sessions from disturbing roommates or family.
- Vibrant RGB for a True eSports Vibe - 20 preset lighting modes with adjustable brightness and flow speed give your desk the glow of a dedicated gaming rig.
- Full Anti-Ghosting, Wide System Compatibility - 104 keys register accurately during rapid combos, and plug-and-play wired connection works across Windows and Mac with no drivers required.
- Pro Software for Even Deeper Customization - Want to go beyond the onboard presets? The companion software lets you design custom RGB effects and program macros with your own keybindings.
There is no dedicated bank of G keys. Macros are available through the software, but the system is basic rather than a substitute for a keyboard with dedicated controls and advanced onboard profiles. AnandTech’s assessment was that the main gaming benefits were the mechanical switches, comfort and lighting rather than sophisticated gaming hardware.
For ordinary PC gaming, the K556’s limitations are unlikely to matter. Competitive players looking for adjustable actuation, rapid-trigger behavior, extensive onboard profiles or tournament-oriented latency should look elsewhere.
Software and programmability
Redragon provides model-specific downloads on its official software page. Select the utility for DEVARAJAS K556; do not assume that software for the K556 SE, K556-RK, K556 TKL or K556 Pro is compatible.
Coverage of the original software found a small, basic utility that could:
- Change lighting effects.
- Program individual keys.
- Store up to three profiles.
- Remap keys to ordinary keyboard commands or multimedia functions.
- Record simple keyboard macros.
- Retain or omit recorded delays.
That is useful, but “fully programmable” should be understood as a manufacturer description, not as QMK/VIA-level firmware customization. The software experience is more limited than the phrase suggests, and availability or compatibility can vary by model, regional version, operating system and hardware revision.
Windows support is the safest assumption for the configuration utility. Redragon lists Mac compatibility for the keyboard, but that does not establish full feature parity in macOS. Buyers who rely on Mac-specific remapping or profiles should verify the exact behavior before purchase.
Rank #4
- Aluminum Build That Won't Wobble - A tank-solid brushed aluminum board keeps every keystroke steady during intense sessions, unlike the flex you get from plastic-frame keyboards.
- Swap Switches Without Soldering, Smooth and Quiet - Quiet linear switches with sound absorbing foam give a clean, low-noise keystroke, and the upgraded socket accepts almost any 3-pin or 5-pin switch.
- Eye-Catching Gradient Keycaps Meet Vibrant RGB - Shine-through gradient blue keycaps make the 18-mode RGB pop, giving your setup a distinct look beyond a standard black board.
- Full Anti-Ghosting for Fast-Paced Games - 104 keys register accurately even during rapid multi-key combos, so your inputs land exactly when you press them.
- Pro Software for Even Deeper Customization - Want to go beyond the onboard presets? The companion software lets you design custom RGB effects and program macros with your own keybindings.
Hot-swappable switches: the K556’s strongest feature
The K556’s hot-swap design lets you replace individual switches without desoldering the keyboard. Redragon advertises compatibility with “99.8%” or more of switches, and the package includes eight spare switches plus a switch puller. AnandTech also confirmed that the switches could theoretically be replaced without dismantling the board.
Free tools Windows power users keep installed
One-click scans. No signup required.
The 99.8% figure is a manufacturer claim, not an independently verified universal compatibility standard. In practice, check that replacement switches use the appropriate MX-style physical footprint and that their pins and LED arrangement suit the board. Physical compatibility does not guarantee identical RGB brightness, sound, fit or firmware behavior.
Hot-swap sockets are convenient but not indestructible. Bent pins, angled insertion or excessive sideways force can damage a socket or pull it from the PCB. A replacement procedure should be conservative:
- Disconnect the keyboard.
- Remove the keycap.
- Use a proper switch puller on the switch housing.
- Inspect the replacement switch and straighten its pins if necessary.
- Insert it vertically without forcing it.
- Reconnect and test the key before reinstalling the keycap.
Stop if the socket moves, lifts or appears detached. A loose hot-swap socket is a PCB repair problem, not simply a bad switch.

The software does not detect the keyboard
- Connect it directly to the computer instead of an unreliable hub.
- Confirm that the utility is for the original Devarajas K556.
- Close other keyboard-control programs.
- Reconnect the keyboard and restart the utility.
- Try another USB port and, if possible, another computer.
- Do not flash firmware intended for the K556 SE, Pro, TKL or another related model.
- Contact Redragon support if the correct utility still cannot detect it.
The model separation on Redragon’s download page makes incorrect software one of the first things to check.

The keyboard slides or marks the desk
The feet and anti-slip pads were a weak point in AnandTech’s sample, especially with the feet extended. A desk mat can improve grip and prevent the metal front edge from contacting a soft surface directly.
Original K556 versus K556 variants
The K556 is the original model discussed here. The K556 SE, K556 Pro, K556 TKL and K556 SP are separate products. Do not merge their specifications into the original K556.
Redragon markets the K556 SE with features including PBT keycaps, a noise-dampening kit and custom linear switches, making it a potentially better fit for buyers willing to pay for an upgraded typing experience. Exact current pricing and availability should be checked on its official product page.
The K556 Pro may be a newer or more feature-rich family option, but its precise connectivity, switch, software and pricing differences should be verified on its dedicated listing. A review of a Pro or SE model should not be treated as a review of the original K556.
Price and availability
Redragon’s US store listed the original K556 at $59.99 when checked for this article. The same listing showed the Red switch option as temporarily out of stock in the United States. That price and stock status are time-sensitive, so confirm them at checkout.
Before ordering, verify:
- Original K556 versus SE, Pro, TKL or another variant.
- ANSI versus ISO or another regional layout.
- Brown versus Red switches.
- Included cable, spare switches and accessories.
- Seller-specific warranty and return terms.
- Availability of the correct software for your exact revision.
Support and warranty treatment can vary by seller and region. Keep the receipt, model number, serial information and original software version. If a controller or firmware failure occurs, it may require manufacturer assistance even though individual switches are replaceable.
Who should buy the K556?
Buy it if:
- You need a full-size keyboard with a number pad.
- You want RGB and mechanical switches at a relatively low price.
- You prefer Brown tactility or Red linear switches.
- You want to experiment with replacement switches.
- You are comfortable using a cable and basic configuration software.
- You value the weight and appearance of an aluminum top plate.
Choose something else if:
- You need Bluetooth or 2.4-GHz wireless operation.
- You want PBT keycaps, premium acoustics or a dampened case out of the box.
- You require QMK/VIA-style customization or advanced onboard profiles.
- You need dedicated macro keys.
- You want adjustable actuation or rapid-trigger gaming features.
- You need a compact keyboard or a quiet office keyboard.
Final recommendation
The Redragon Devarajas K556 is best understood as a value-focused full-size mechanical keyboard, not a modern enthusiast or esports board. Its combination of a metal top, RGB lighting, familiar full-size layout and hot-swappable Outemu switches gives it a convincing budget proposition—particularly when discounted or when switch replacement is important.
Quick wins for a faster PC:
Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Clear out junk files and repair common Windows errorsFree Scan →Buyers should accept the ABS keycaps, basic stabilizer and case details, wired-only connection and rudimentary software. At a price close to newer K556 variants or better-equipped competitors, the original becomes harder to justify. For a first mechanical keyboard, office-and-gaming setup or inexpensive full-size hot-swap board, however, it remains a sensible option if the exact layout, switch type, stock status and support terms check out.
