The Corsair K55 RGB Pro XT gaming keyboard is the latest in a long line of membrane keyboards made by big companies. Mechanical switches and gaming accessories go well together, but they aren’t cheap. Even tenkeyless models often cost more than $150.
Theoretically, this is why the K55 RGB Pro XT is so appealing. Like more expensive mechanical keyboards, it has per-key RGB lighting, programmable macro buttons, and separate media controls, but it only costs $70. So, the K55 Pro XT could be one of the best gaming keyboards for PC gamers who are just starting out and aren’t ready to spend hundreds of dollars on their accessories yet.

Corsair K55 RGB Pro XT review: Design

Instead, the K55 Pro XT seems to have a lot of extra space, whether it’s the large, glossy bar at the top or the large bezels on either side of the black plastic chassis. Compared to the Corsair K70 RGB Mk. 2, the K55 RGB Pro XT isn’t very pretty either. There isn’t an airbrushed metal design, recessed keys, or a metal volume dial. Everything looks plain or cheap, depending on how you look at it. It is all black and simple.
There is also a wrist rest that can be taken off. It has a rough, bumpy surface that makes it pretty comfortable. But when it comes to extra keys, the K55 RGB Pro XT doesn’t skimp. On the left side of the keyboard, there is a row of six macro keys that can be set to do different things. There is an easy-to-use button on top of the keyboard for recording macros, as well as a “win lock” button and a brightness button. You can buy this keyboard from its official website
Corsair K55 RGB Pro XT review: Keys
But when it comes to extra keys, the K55 RGB Pro XT doesn’t skimp. On the left side of the keyboard, there is a row of six macro keys that can be set to do different things. There is an easy-to-use button on top of the keyboard for recording macros, as well as a “win lock” button and a brightness button. This last one turns off the Windows keys and other key combinations (like Alt + Tab) that can be used by accident to leave a game.
Corsair K55 RGB Pro XT review: Performance

The Corsair K55 RGB Pro XT works well with many different types of games. The keys aren’t necessarily better for gaming than they are for typing, but I didn’t find any problems with how they worked for regular play.
Age of Empires III: Definitive Edition, Doom Eternal, Baldur’s Gate III, and Final Fantasy XIV were the games I used to test the peripheral. Whether I was building houses for my Inca empire or shooting demons in the ruins of a destroyed city, the keys worked well.
Corsair K55 RGB Pro XT review: Lighting and software
The $50 K55 RGB Pro doesn’t have per-key RGB lighting, but the $70 K55 RGB Pro XT does. The cheaper option has five different zones, while the XT can be set up in any way you want using their iCUE software.
While still not as robust as other lighting programmes like Razer’s Synapse, iCUE still has plenty of functionality for dialling in colour combinations. Brightness can be changed physically with a button on the top of the board, and iCUE unlocks colour patterns like watercolour, spiral rainbow, rainbow wave, and type lighting.
Corsair K55 RGB Pro XT review: Price
At $69.99, the Corsair K55 RGB Pro XT feels like a very powerful and affordable way to get started with gaming keyboards. Mechanical key switches may be appealing, but they will raise the price and, depending on how you plan to use them, may not be worth it. After all, there is something nice about how the membrane on the K55 RGB Pro XT cuts down on noise.
Final Words
The Corsair K55 RGB PRO XT is a good keyboard for gaming. But the quality of its construction isn’t great, and the rubber dome switches are hard to press and have a long pre-travel distance. It has a very low latency, dedicated macro keys, and software that lets you change things. It also has RGB backlighting, and each key has its own lighting that can be changed separately.

FAQs
Is K55 RGB Pro XT mechanical?
The backlighting on the K55 RGB PRO XT is RGB, and each key can be set to a different colour. It also lets you use Corsair iCUE to add dynamic lighting effects to some games. Both the SteelSeries Apex 3 and the Corsair K55 RGB PRO XT are non-mechanical gaming keyboards with similar performance.
Is Corsair K55 RGB PRO good for gaming?
But all in all, it’s still a good alternative to many other keyboards in the same price range. The Corsair K55 RGB PRO is a good choice for most games, such as FPS, RTS, and platform games, as long as you don’t use it for long hours every day. The only bad thing about it is that it is made of plastic.
Is the Corsair K55 worth it?
Our Verdict. The Corsair K55 is only good for gaming because its rubber dome switches need a lot of force to work. This makes the keys feel less responsive. On the other hand, it has very low latency, zone-lit RGB lighting, six dedicated macro keys, and all of its keys can be programmed.
