Cooler Master SK653 Review

Over the summer, I was hanging out at McDonald's at night with a group of friends when one of them asked me, in a not exactly quiet voice, if two people in our group were dating. I do not believe the guy heard what my friend said, but the girl certainly did as she turned around and gave me a death glare. I am pretty good friends with her, and I think the death glare was more than enough to communicate some message. Therefore, I looked back at my friend who asked the question and just laughed. "Do you think she has a boyfriend?" Just to clarify, the two of them were not dating or even interested in each other, and I also got a solid punch on my arm from the girl as a result of that response. I probably could have just answered no, but either way, my message was accurately communicated. It seemed the girl wanted me to clarify that her and the guy were not dating without me poking fun at her, but can we really have the best of both worlds all the time? Over the years, we have reviewed many mechanical keyboards here at APH Networks, which ranges from large feature-loaded keyboards with an optional display like the Corsair K95 RGB Platinum XT to budget compact models like the Kitcom NK60T. But what if you want a premium mechanical that has the best of both worlds, minimum in size and maximum in features? Cooler Master has a lineup for you. The SK-series has been well-received on this website since 2019 with its low-profile design and feature-loaded models. Today, we have yet another model from the lineup, the SK653. The SK653 is a full-size version of the SK622 that features TTC KS32 switches and standard low-profile keycaps. Will it be a worthy successor to the SK650? Read on to find out!

Our review unit of the Cooler Master SK653 came in a medium-sized, brown corrugated cardboard box from Cooler Master's American offices in Claremont, California, USA. Using FedEx International Ground, the keyboard arrived safely to us here in Calgary, Alberta, Canada for our review today. It came along with the MM731 mouse, which will be reviewed by my colleague Aaron Lai.

The retail box design for the Cooler Master SK653 is quite literally identical to the last Cooler Master keyboard I reviewed, the SK622, with the obvious exception of the name of the product. The white background is complemented by mainly black text for maximum contrast along with a burst of purple to help you remember who made it. Cooler Master's logo and slogan is at the top left corner, backlight-activated image of the keyboard is printed across the center, and the model name and product description are located at the bottom left corner. On the opposite corner, three icons indicate its MasterPlus+ software, Bluetooth connectivity, and RGB backlighting. Our particular unit has low profile TTC red switches. Feature highlights can be found on the remaining sides of the box.
