The Corsair K55 RGB PRO XT is a very good, entry-level gaming keyboard with rubber dome switches. It's an update of the Corsair K55 RGB Gaming Keyboard with acceptable build quality, very low latency, and good ergonomics, including a detachable wrist rest and one incline setting. It has dedicated media and macro keys and companion software that's compatible with Windows and macOS. Unfortunately, the rubber dome switches only provide mediocre typing quality as all keys wobble significantly and feel fairly heavy to press. It has RGB backlighting with individually-lit keys, but it only has five customizable lighting zones. It's very similar to the Corsair K55 RGB PRO, but that one lacks individually lit keys and doesn't support dynamic in-game lighting with certain games through Corsair's iCUE software.

Our Verdict

8.3 Gaming

The Corsair K55 RGB PRO XT is a great gaming keyboard. However, its build quality is only adequate, and the rubber dome switches are fairly heavy to press and have a high pre-travel distance. It has very low latency, dedicated macro keys, and companion software for customization. It also has RGB backlighting with individually-lit keys, although there are only five customizable lighting zones.

Pros
  • Remarkably low latency.
  • RGB backlighting with individually lit keys.
  • Good ergonomics.
  • Dedicated macro keys and all keys are macro programmable.
Cons
  • Individual key lighting can't be customized; only five customizable lighting zones.
  • Keys feel heavy to press.
  • Only adequate build quality.
2.9 Mobile/Tablet

The Corsair K55 RGB PRO XT is a wired-only keyboard that isn't designed for use with tablets or mobile devices.

7.2 Office

The Corsair K55 RGB PRO XT is satisfactory for office use. It has very quiet rubber dome switches and good ergonomics with a detachable wrist rest and one incline setting. Unfortunately, the typing quality is mediocre because all keys wobble noticeably, have a fairly high pre-travel, and feel heavy to actuate.

Pros
  • Good ergonomics.
  • Very quiet rubber dome switches.
Cons
  • Keys feel heavy to press.
  • Only adequate build quality.
6.8 Programming

The Corsair K55 RGB PRO XT is alright for programming. It has adequate build quality and mediocre typing quality. That said, it has good ergonomics with a detachable wrist rest and one incline setting. It has RGB backlighting with individually-lit keys but only has five customizable lighting zones. There are also six dedicated macro keys, all keys are macro-programmable, and the companion software is compatible with Windows and macOS.

Pros
  • RGB backlighting with individually lit keys.
  • Good ergonomics.
  • Dedicated macro keys and all keys are macro programmable.
Cons
  • Individual key lighting can't be customized; only five customizable lighting zones.
  • Keys feel heavy to press.
  • Only adequate build quality.
4.8 Entertainment / HTPC

The Corsair K55 RGB PRO XT is bad for home theater PC use. It's a wired keyboard with no wireless connectivity options, and it has no trackpad, so you may need to use a mouse to navigate menus. On the other hand, it has dedicated media keys and RGB backlighting with individually-lit keys, though it only has five customizable lighting zones.

Pros
  • RGB backlighting with individually lit keys.
  • Dedicated media keys.
Cons
  • Wired-only.
  • Individual key lighting can't be customized; only five customizable lighting zones.
  • No trackpad.
  • Only adequate build quality.

Build Quality
Keycap Material ABS

The Corsair K55 RGB PRO XT has adequate build quality. The body and baseplate are made of plastic and flex quite a bit, while the top of the keyboard has a glossy finish that shows fingerprints and scratches very easily. There's significant wobble in all keys, and the laser-etched ABS keycaps feel cheap, slippery, and are prone to showing oils from fingers. The rubber pads on the bottom feel stable, but the keyboard may slide around more with the feet extended. This keyboard is rated IP42 against solids and liquids, but this isn't something we test.

While the Corsair K55 RGB PRO XT has individually lit keys, unlike the Corsair K55 RGB PRO, there are still only five customizable lighting zones. This means you can only customize a zone's lighting rather than each key's lighting. Unfortunately, our testing method doesn't take this into account, so this keyboard scores as high or higher than some keyboards with full RGB lighting and individually-lit keys that you can customize independently. Corsair also advertises that some games can integrate with the iCUE companion and produce dynamic lighting effects that react to in-game actions and events, but this isn't something we test.

This keyboard has rubber dome switches. They're fairly heavy to press, and they have a somewhat high pre-travel distance. While these characteristics may help you avoid making typos, you may also get tired when typing for some time. The operating and actuation forces are slightly lower next to the nearly identical Corsair K55 RGB PRO, but this is likely due to manufacturing tolerances and may vary between units.

Typing Experience
Typing Quality

The Corsair K55 RGB PRO XT has mediocre typing quality. The keycaps are ABS plastic and feel slippery, which may lead to more typos. There's also a considerable amount of wobble in the keys. The rubber dome switches offer some tactile feedback, but they feel mushy. Also, you may experience fatigue after typing for long periods because the keys can feel heavy to press. That said, the larger keys feel well-stabilized, and they actuate smoothly.

Corsair K55 RGB PRO

The Corsair K55 RGB PRO and the Corsair K55 RGB PRO XT are nearly identical wired gaming keyboards with rubber dome switches. The K55 RGB PRO XT has RGB backlighting with individually lit keys. However, it still only has five customizable lighting zones. It also supports dynamic lighting effects with certain games.

SteelSeries Apex 3

The Corsair K55 RGB PRO XT and the SteelSeries Apex 3 are non-mechanical gaming keyboards with comparable performance. The Corsair has significantly lower latency, individually-lit keys, but only five lighting zones, and its companion software has onboard memory, but you can't sync settings to the cloud. On the other hand, the SteelSeries has ten zone RGB backlighting, but the keys aren't individually backlit. That said, it feels sturdier, it has a wheel on the top right, and it has more stable keys that offer a better typing experience than the Corsair.

Keychron K6

The Corsair K55 RGB PRO XT and the Keychron K6 are very different keyboards, but the Keychron is a more versatile keyboard, while the Corsair is better for gaming. The Keychron is a compact 65% mechanical keyboard that you can use wired or wirelessly over Bluetooth. It's available with tactile Gateron Brown, linear Red, or clicky Blue switches. It feels better built and has two incline settings, though it lacks a wrist rest and has no companion software for customization. It also has RGB backlighting with individually-lit keys. On the other hand, the Corsair is a full-size keyboard with rubber dome switches. It only has one incline setting but has an included wrist rest and lower latency. It also has companion software that's compatible with both Windows and macOS. Unfortunately, while it has full RGB backlighting with individually-lit keys, it only has five customizable lighting zones.

Corsair K100 RGB

The Corsair K100 RGB is a much better gaming keyboard than the Corsair K55 RGB PRO XT. the K100 is a mechanical keyboard that feels much better-built, has an additional incline setting, and has a padded wrist rest, a USB passthrough, and a wheel in the top right. It also has full RGB backlighting with individually-lit keys, and it's available with linear Cherry MX Speed or linear Corsair OPX switches. On the other hand, The XT is a non-mechanical keyboard with rubber dome switches, a hard plastic wrist rest, and while it has individually backlit keys, it only has five RGB lighting zones.

HyperX Alloy Origins

It also feels much better-built and has full RGB backlighting that you can customize on a per-key basis using the companion software. It also has a detachable USB-C cable and two incline settings, but it lacks a wrist rest. On the other hand, the Corsair has rubber dome switches and RGB backlighting with individually lit keys but only five customizable lighting zones. It also has software compatible with Windows and macOS. Both keyboards have exceptionally low latency, and while the Corsair's is slightly lower, it's unlikely to be a noticeable difference.

Logitech G413

The Corsair K55 RGB PRO XT and the Logitech G413 are both full-size gaming keyboards, but the Logitech is a better gaming board overall. The Logitech is a mechanical keyboard with Romer-G tactile switches with short pre-travel distance and good tactile feedback. It feels better built and has full red backlighting with individually-lit keys, though there's also a variant with white lighting. It also has media hotkeys and a USB passthrough, but only dedicated macro keys. On the other hand, the Corsair has rubber dome switches that feel fairly heavy and have a long pre-travel distance.
