by Gavin Bonshor on January 10, 2019 11:00 AM EST
Cooler Master has announced its first range of wireless mechanical keyboards, the SK621, the SK631 and SK651 models. All three models feature Bluetooth 4.0 functionality and have a slimline profile with Cherry MX low profile switches.
Cooler Master SK631
The SK621, SK631 and SK651 models feature a slim profile mechanical frame with the aim to provide a balance between work and gaming. All three models include the use of Cherry MX low profile switches which have a shorter travel distance and actuation point than standard Cherry MX switches; these switches are based on the Cherry MX Red switches.
Users can use these new models either wired or wireless thanks to Bluetooth 4.0 connectivity built-in. Each keyboard comes supplied with a USB Type-C USB cable. The SK621, SK631 and SK651 keyboards also feature per-key backlighting and surrounding light bars which can be customized through its Portal software. The SK621 has a 65-key layout, the SK631 is more compact with a tenkeyless design and the SK651 features a full-sized layout, but keeping in with the SK series thin design.
Availability and pricing information is currently unknown at the time of writing.

Looks pretty good. I have a friend that's only comfortable using low profile keyboards after getting used to using his work laptop on-the-go and having a laptop for his main personal PC for several years. They never really liked the travel distance for regular keyboards, or mechanical ones, and while there have been a few low-profile offerings like the Tesoro Gram and I believe there was a Razer one, too, many have been pretty expensive.I can see the bluetooth 4.0 feature being nice for wireless connectivity.

Looking at the switches, the length of travel isn't *too* different from normal Cherry MX: 3.2mm rather than 4mm. Sure, that's a 20% improvement, but it's not on the same level as a laptop keyboard.Really, the "low profile" bit is about how the switches are half the height compared to a normal Cherry MX switch, since they telescoped the stem. I suspect compatibility with aftermarket keycaps will be limited because of the shortened travel.

I don't think the shorter stem is going to be much of a problem for aftermarket keycap compatibility.What does look like it could be a problem however is that the switches are wider up-top than regular Cherry MX. The edge of the housing would hit the insides of the sloping walls of thick-walled "Cherry-profile" keycaps before the key has been fully depressed.

Early reviews have revealed that the stabilisers are different: neither Costar or Cherry-style.duploxxx - Thursday, January 10, 2019 - link

"Users can use these new models either wired or wireless thanks to Bluetooth 4.0 connectivity built-in."That probably means there is a USB cable so that someone in your situation would not be forced to resort to a wireless connection. With that said, I haven't really noticed that wireless connections introduce any sort of problem. I use a wireless Logitech K400 keyboard and touchpad alongside a $11 Jelly Comb branded slim wireless mouse when my laptop is docked at my desk for gaming. Both don't seem to harm my gaming and the mouse is a fair bit more reliable and accurate than the Razer Deathadder Chroma it replaced since I'm not dragging a wire around with the mouse.

For a keyboard that's fine, its not on the same level as a mouse. Wireless controllers have been the primary for years, with wired really only being reserved for fighting game events (and even then its mainly to prevent it from being used as an excuse).plsbugmenot - Saturday, January 12, 2019 - link
wireless peripherals are at a level now where there is really no difference in response time. I use the Logitech G613 and it has a 1ms report rate, faster than many wired keyboards.Ikefu - Thursday, January 10, 2019 - link
If they were Brown switches instead of Red I'd consider pre-ordering one. I just can't get use to the no click on reds. Still, excited to see more low-profile options entering the market. I have a Havit low-profile with blues and its amazing (minus the extreme clicky noise)Catchy Title - Saturday, June 15, 2019 - link
Nice keyboards! Hopefully, they will be available in my zip code https://worldpostalcode.com/united-states/new-york... soon. I'm in search of decent wireless keyboards. Previous ones, which I used, didn't serve long :c
