Corsair K57 RGB Wireless Review

Performance Testing
At the £90/$100 price point, the market is awash with many excellent keyboard choices, particularly if you aren’t bothered about having mechanical switches. The fierce competition surrounding the price point makes the K57s performance all the more important.

Starting off with build quality, the K57 doesn’t meet the usual level that we’ve come to expect from Corsair. While an all-plastic construction helps keep the keyboard under 1kg in weight, it also introduces noticeable flex if you try to use the keyboard on your lap. The plastic keycaps and rubber dome key switches also feel equally ‘cheap’, for lack of a better phrase. A metal backplate feels almost mandatory at this price point. One redeeming feature is the 1.8M long USB cable with solid plastic mouldings on each end, this feels like a quality item, if not a little bit redundant for a wireless keyboard.

Having tested keyboards like the Razer Cynosa Chroma and ROCCAT Horde AIMO with their rubber dome switches that have been designed to feel like mechanical keys, it felt like they were almost a good trade-off between the higher cost of mechanical keys with their much nicer feel, and the vastly lower price of rubber dome. However, with the Corsair K57, they’ve stuck to an entirely rubber dome feel, with no real attempt to change the actuation or travel of the key. Each key press has to be bottomed out fully, with a reasonable amount of pressure, with little-to-no tactile feedback whatsoever. If Razer and ROCCAT can manage it, why can’t Corsair? Granted, those two keyboards aren’t perfect but the Corsair isn’t even on speaking terms.

Comfort, on the other hand, is great. The large wrist rest is made of a soft-touch plastic that is gentle on the wrists and the small feet on the rear of the keyboard help to angle the keyboard for a “sitting back in the chair” position. The wide shape of the keyboard also makes it easy to place on your lap if you want to use the keyboard on the sofa, in front of the TV.

Having dedicated media and macro keys, particularly in this price range, is somewhat rare but Corsair have done the end-user a solid favour by including them, having said that, it would’ve been much nicer if they could’ve included their volume roller instead of buttons. We love that volume roller on their other keyboards.

Corsair have gone to great lengths to develop their CAPELLIX RGB LEDs with power efficiency, vivid colours, longer lifespan and higher LED density for a given area all add up to a more enjoyable experience, if RGB lighting floats your boat, that is. The effort they’ve put into developing these LEDs shows hugely, with beautiful lighting effects with immense brightness, way in excess of anything we’ve seen before; particularly impressive for a battery-powered keyboard.

Wireless transmission technologies have, over the years, improved hugely. We no longer suffer from drop-outs and abysmal transfer distances, now being able to sit at the other side of the room with stutter-free operation. Corsair have gone one step further with their Slipstream wireless connection technology, offering sub-1ms response times for the best possible gaming experience. Corsair have also installed Bluetooth connectivity to allow connection to a TV, games console, mobile phone or just about anything that uses Bluetooth.
