Superb – GMMK 3 PRO HE 75% Wi-fi Corridor-Impact Linear Swap Gaming Keyboard with Fast Set off and Adjustable Actuation – Silver

Keyboard was high in not just quality but also performance

The GMMK 3 Pro HE is my first ‘real’ mechanical keyboard and so far it has been a generally good experience for me with a few bumps. The keyboard itself has a great build quality and the Fox HE hall effect switches have a nice feel and sound. The software also has a ton of cool customization you can do with those switches. The experience of using the software for me has been buggy though, even for the prerelease build that I have been using. These are both things that could potentially be resolved in future updates, but it’s something I need to point out in the here and now and from what I can see Glorious is not well known for their software.
In the box you’ll get the keyboard and a variety of additional parts, including:
Keycaps for macOS
Spare gaskets, O-rings, and screws
A screwdriver, keycap puller, and switch controller
A variety of sample switches to try out
A USB-A 2.4 GHz wireless receiver
A white braided USB-C to USB-A cable for charging and wired operation
The build quality of the keyboard is fantastic. It’s set in a very heavy aluminum case and feels well put together – the whole thing weighs about 3.4 lbs. At the top right is a knurled volume knob that turns and clicks that is also aluminum and next to that is a gold accent piece that houses the LED indicator light. The preinstalled keycaps are a bright white color, which does look good though I personally think a more neutral gray color might look better against the silver top case. I’m also not a fan of the Caps Lock key being swapped out for a down arrow and the Enter key reading ‘ASCEND’. I’m not a fan of the gold accent piece either, but fortunately all these pieces can be swapped out for other keycaps and I assume Glorious will sell different colors of the LED cover in the future as well. The back of the keyboard has the USB-C connection, as well as mode switches for Mac/Windows and 2.4GHz/Wired/Bluetooth and this is also accented in gold.
I thought the sample switches in particular were a nice addition as I was able to actually try them out. I do really like the Fox HE switches that are preinstalled, but I also would strongly consider replacing them with the Lynx or Panda switches in the future and it’s not something I personally would have even given much thought to had I not had a chance to try them. One thing I noticed while swapping the switches though was that the included keycap and switch pullers don’t seem to be the same as what Glorious offers on their website. The keycap puller for me worked fine, but did require an uncomfortable amount of pressure to get it and underneath the keycaps. The switch puller I had a lot of issues with and I ended up damaging most of the sample switches trying to remove them from the base. I haven’t worked on keyboards like this in the past, so this could be user error, but I felt I was very careful about how I was using the tool and it was just not a great experience trying to get the switches out. If I decide to completely replace the switches in the future I will probably purchase a different switch puller. The GMMK 3 Pro HE can use both Glorious’ hall effect switches and standard MX mechanical switches.
Setting up the keyboard with the Glorious Core 2.0.2 software I was provided was easy enough. The keyboard was immediately recognized by my PC and the software did recognize the keyboard. The layout of the software is basic, but mostly straightforward and allows you to customize the polling rate/response time, lighting, keybindings, and actuation points of the switches. One of the neat things you can do with the software is you can program each key to activate a different function depending on what position it’s pressed in as the hall effects can detect where specifically you are in the keyboard press. The lighting effects are neat as well and let you do per-key customization and have some cool preset effects like a ripple that shoots light out from whatever key you pressed on. The software doesn’t seem to have a ‘live’ connection with the keyboard though and each time you make a change that needs to be saved to the keyboard. The upside of this is you don’t have to depend on PC software to maintain your keyboard functions, but the downside is it makes configuring the keyboard a bit cumbersome. I also ran into some issues getting some of my lighting effects to save to the keyboard and ended up having to go wired in some circumstances to get them pushed through. I do have to mention again this is prerelease software, though I ran into additional problems that were not listed as known issues. Hopefully by the time that it is officially released it will have improved and once all changes are made you don’t really need to even use the software anyway.
I used this as my standard keyboard for a full work day and the typing experience on it is great, though I experienced some connection drops a few times an hour throughout the day and that was a bit concerning to me. I don’t know if this is down to a poor connection from the receiver or if there was some issue with the dock I was using, but I did eventually move the receiver from the back of my Thunderbolt dock directly onto a USB port on the front of my laptop and did not have any further issues. On my PC at home the connection seems to be solid. The keyboard works both wired and wirelessly, so if the consistency of the connection is ever an issue the USB-C cable is always an option. I have not tried the Bluetooth connection, though I imagine for most purposes related to gaming you’d want to go 2.4GHz or wired anyway. One problem for anyone who might be using this for general purpose keyboard activities is there is no Caps Lock indicator on the keyboard, except for the LED lights on the side of the case are blinking instead of solid. If the Caps Lock key itself could somehow be illuminated differently when it’s on that would be nice, but so far I have not found a way to do this in software if that functionality is there. The software also does not seem to accurately indicate the charge level of the keyboard right now and it died unexpectedly on me after about 8 or so hours of use. The quoted battery life on the box for 2.4GHz operation is 24 hours, but I assume this is with the LED lighting turned off.
I’m really happy with the quality of this keyboard and the experience of actually using it has been great, but it’s let down by buggy software. I’m hoping Glorious is able to make improvements on it in the meantime, but for now it’s something to be aware of.

The GMMK 3 PRO HE 75% Wireless Hall-Effect Linear, IMHO, is the pinnacle of gaming keyboards.
What Glorious has put together in this “Pro” 75% foot print keyboard is nothing short of amazing.
From the moment you unbox this beast, you’ll notice immediately that it is heavy as an anvil. Some people may not like that but I prefer weighty construction over the more typical lightweight and sometimes cheap feeling gaming keyboard offering these days. Is this a keyboard you’ll eagerly want to throw in a backpack and take to your next LAN party or friends home? Probably not… but portability isn’t my thing and I’ll take that “built like a tank” feeling every day of the week.
Before one gets to the stage of tweaking the actuation settings or messing around with the color palette, there will still be this mesmerizing effect of taking in the default Glorious lighting scheme and the typing experience. These Glorious keys are the best I’ve ever laid my fingers on. They are consistent across the entire board and have an inexplicable feel to them, a smooth travel sound and excellent key caps too. Inside the control center app are a broad selection of light effects I would call excellent and some of the best offered as a grouping of “built ins”.
Being a multi-functional keyboard, you have the ability to use the onboard 2.4 GHz connectivity, blue tooth (chosen with a slider switch) or a hard wired arrangement – with the included USB-A to USB-C braided cable. The included cable isn’t the typical coiled Glorious offering but it is still top quality.
As with their other GMMK Pro offerings, there is a rotary dial/switch which is smooth and precise.
One thing worth mentioning and I don’t consider it a short-fall is that this keyboard has one angle of orientation. In other words, there are no selectable legs underneath – so you’ll either like the somewhat low-profile aspect of the orientation or you won’t. For me, it’s perfect – but everyone is different – so know that going in!
All-in-all, the build quality of the GMMK 3 PRO HE 75% Wireless Hall-Effect Linear is simply the best of the best and hits all the right “notes” for my particular taste in gaming keyboards.
Moving to the Glorious Core software, you will find everything you need to customize the RGB look and actuation response + macro like functions. From what I can tell, the actuation response of these linear switches is consistent across the adjust-ability range – dare I say – in a “linear” fashion. This is my second experience with customizable actuation points and previously (on a competitors keyboard…) I wasn’t much impressed. Not so with this keyboard. It works amazingly well and everyone should find a good ‘set point’ for their preferred selection of keys. I found my preferred actuation point a little quicker than the default but not too aggressive and set this way, I enjoy typing on this keyboard much more than on my GMMK Pro 3 – which is tethered to my primary, gaming/productivity machine – or had been until now. For those demanding some of the most advanced key binding controls available, you will certainly not be disappointed in what the GMMK 3 PRO HE 75% offers in the app.
Highlighting the RGB functionality, there is a diffusion plane surrounding the switch bodies that looks amazing without producing a lot of distracting ‘hot spots’. There are light strips on the left & right sides of the keyboard frame that look great too and can be programmed to provide feedback – like caps-lock being engaged.
I do like that fact that you can change to a Glorious coiled cable or one of a different brand with USB-C termination. And another mind blowing bonus Glorious included with this “kit” are single samples of 4 of their other Glorious HE switches; Fox HE (smooth linear with creamy sound), Lynx HE (smooth linear with marbly sound), Panda HE (rounded tactile with a thocky sound) and finally Raptor HE (clicky sound & feel). More mfg’s should offer this type of switch introduction, considering what keyboard are costing now days and I’m not surprised one-bit that Glorious added this touch.
For those that simply want the best, this keyboard is totally flexible and does it all – – and is probably the one keyboard I can confidently say is worth every penny.
Pros:
Solid, heavy & dense construction with absolutely no structural resonances
Excellent lighting diffusion plane and crisp key cap shine-through
The key caps are perfect – but that is totally subjective
Removable USB cable – USB-C connection point. Yes!!!
Up to 8K polling rate and as low as 2 ms response time control
Rapid Trigger, Customizable Actuation Point & Dynamic Keystroke + Advanced key binding capability
Sample switches included for those eager to move to something different – down the road
Well designed/laid out Glorious Core control center app
Cons:
Absolutely none!
I am truly struggling to find anything this keyboard design left off the table!

What happens when you take one of the best early PC Memes and create an entire peripheral line from it? Well, you get the Glorious brand and an amazing, nearly perfect keyboard like the GMMK 3 Pro HE Wireless. I’ll be honest and admit I didn’t even know this brand Glorious was an actual thing even though I would consider myself PCMR and PC enthusiast my entire adult life. I’ve tended to stay with the tried and true mainstream brands like Logitech, but the downside is that these brands tend to lag behind in terms of technology since they have to mass market and spend more time in R&D, while a smaller enthusiast brand like Glorious are designed to be cutting edge all the time.
The main thing I noticed right away with this keyboard was it had all of the latest features you find from the small batch curated “drop” and kickstarter type keyboards where enthusiasts in the know pre-order/pledge and seed development with their own money. This allows more freedom to implement bleeding edge tech.
In this case, the killer feature is HE, which stands for Hall Effect. This is the implementation of an old physics discovery where a change in the magnetic field is detected and converted into an electrical signal. When it comes to keyboard, this allows the keycap to register and hold a stroke at different actuation levels, pressure levels, and all kinds of other analog-like control that go beyond the typical binary result of a keyboard registering a keystroke.
The Core v2.0 software I used to test allowed me to easily change the actuation point of the keys, although I’ll be honest and say the adjustments did not seem to matter that much at the top of the keystroke, but was more obvious when setting to 3.7mm for the lowest keystroke which required me to bottom out the key to register a stroke. I have optical keyboards that are a LOT more sensitive, probably too sensitive. Actuation point can be set per key or globally. There is also the ability to set keystrokes/macros, lighting, keybindings and performance/polling rates/input latency. I’m not sure how much this will impact actual performance for anyone since 8000Hz or even 1000Hz is way overkill, but I am sure this will impact battery life which I will get to later.
The keys themselves are linear, although they have an interesting suction feel and have a very slight resistance throughout the key press. Typing is also relatively quiet compared to linears like Red/Black that are still super loud when the keys bottom out. These switches definitely have some kind of dampening foam that gives the keys a softer landing when bottoming them out and there’s almost a suction feel to the keys when they raise back up. Some people might love this, others might not as there are times it is reminiscent of a rubber dome keyboard of old…. The keys are unfortunately in a “well” and not flush to the keyboard body, which means they are harder to clean out over time since dust and such can get inside, but the GMMK3P comes with 2 key pullers and are designed to easily pop out each key.
The keyboard itself is AMAZING build quality, everything you would expect from the PCMR keyboard that leaves nothing to be desired. Its a solid hunk of aluminum and probably weighs 5lbs. Seriously its massive and dense and looks/feels amazing. Anyone who sees the keyboard is going to be amazed and maybe wonder if its an alien artifact on your desk. RGB is excellent, keycaps are super high quality and solid feeling, each key is consistent feeling, even the larger keys like spacebar, backspace, enter (Ascend), tab, shift etc. From the accessories kit, it looks like they have some foam landers that help with the consistent feel that can be changed out.
Keyboard layout is said to be 75%, but they definitely squished it down to maybe 68 or 70% by moving the arrow keys and the home key cluster to vertical. I don’t love this, I would’ve preferred them to keep it the same, but it is MUCh better than the 60% keyboards that totally omit arrow/home keys and also Function-keys.
So, why did I take a star off since all of my comments seem to be overwhelmingly positive? Because there’s clearly a premium as a new offering in the GMMK lineup that this is a wireless keyboard. But here’s my problems with that:
1. As mentioned, the keyboard is incredibly heavy. So heavy that it is unlikely you will take it with you and move it. It is seriously like 5lbs and while small, I would not consider it portable.
2. The battery life is BAD. Like 2 days of playing Diablo 4 just for 5-6 hours each session for a total of 12 or so hours bad. My other keyboards last at least a week, if not more, and that is also using them for work at home 2-3 days a week too. Some of this may be due to the RGB lighting settings as well as reducing input latency to 2ms, but polling rate is just 1000Hz. 8000Hz you probably just want to keep it plugged in. The first time the battery ran out I simply couldn’t believe it. Just 2 days of use and out of nowhere in the middle of a Diablo 4 infernal horde run, my inputs stop. If it was Hardcore that character would’ve been RIP. So I charged it up and used it again just to make sure and yep, just 2 days maybe 12 hours of moderate usage and battery dead. Worst part is that the Core v2.0 software always showed 100% battery and did NOT accurately update the battery status. I am sure this can be fixed to show the actual battery level, but its a shame they didn’t carve out some additional aluminum from the chassis and add a bigger battery.
3. Another huge benefit of wireless for me is that they typically allow both 2.4RF via USB dongle as well as BT connectivity without any dongle. This is amazing because you can quickly switch inputs between your main gaming PC and a work laptop or peripheral device at your desk without having to move the keyboard or have a 2nd keyboard. The downside is that the mode switcher, along with the USB-C charging port, is in an indented part of the top/front of the keyboard that you cannot see. On top of that, the toggle is not a simple key press, it is a switch that is STIFF so get ready to scuff some fingernails and remind yourself how heavy this keyboard is bc you have to lift it to see where the toggle is.
4. As mentioned the software Core v2.0 is pre-release and does not seem to be fully functional which is understandable. I didn’t ding off this but they really need to fix this especially the battery meter.
Is this an amazing keyboard? Yes it certainly is. In many ways its the nicest keyboard I’ve ever laid my hands on. But its not perfect in terms of design and functionality, there’s still a lot they can improve upon and I am sure Glorious will do that. It is clear this company is run by PC enthusiasts and developers who understand what other PC enthusiasts want, they just need to keep iterating and getting it right.
