[ Review ] Logitech Gaming Headset G633 Artemis

Presenting Logitech’s newest flagship gaming headphone: the G633 Artemis Spectrum. With its assortment of RGB LEDs, Tron-inspired styling, and a bevy of buttons, can the G633s make a place for itself in the exceedingly crowded $150 range? Let’s see how the Logis stack up.


Aside from the Cortana-blue looks and faux-chrome embellishments, the Logitech design team really knocked it out of the park with the G633s. There was clearly a lot of smart thinking that went into these cans, from the double input ports to the slick peak-a-boo mic. The USB cable is removable, so any micro USB cable, be it braided or otherwise, will work. The included cable is plenty long but, alas, is a generic black plastic affair rather than the braided variety found on competing headphones and Logitech’s own G35s.

The 3.5mm headphone jack is a nice touch, giving you the ability to hook them up to your phone or other devices. If you choose USB, the volume control adjusts the overall system volume and not the internal headphone volume.

Finally, the headphones twist flat for portability, though other adjustments are missing. Aside from the basic strap adjustments, the ear cups can’t be twisted to fit your head like more expensive headphones from big players.

If you’re looking upstream, Logitech’s G933 headphones give you the option of 3.5mm jack or 2.4GHz wireless with 12 hours of charge. Cutting the cords bump the cost of the G933s up an extra $50 to $199.

Build Quality

Even though the metal bits look like they’re forged from the fires of a dying star, the fancy pieces are all matte or chromed plastic. It’s a convincing look, but once you hold the headset, you realize how light and plastic they really are. At $149 some cut corners are to be expected. Then again, other headphones in the same bracket feel just a little more put together. Even Logitech’s own G35s, despite being an older and cheaper model, are heavier and a notch above the G633s in terms of build quality, materials and execution.


Here we get to the subjective of subjective — I didn’t like the way they fit. Or, more precisely, my lumpy head with its Neanderthal occipital bun wasn’t having the Logis. Others really like the fit of this particular headset, so go figure. I find the flat band or double band style to be a better choice for my long-term gaming, but you may love the thinner band with thicker padding design. Logitech’s G35s had a band twice as thick with replacable leatherette pads, compared to the G633s narrow fabric pad.

Also, I found the ear cups to get a little rough against my head. The material is cloth mesh, not velour, microfiber, leather, pleather, tanned goat hide or whathaveyou. It’s okay for $149, but it’s clear the G633’s designers spent their budgets in other places, like fancy buttons, not in the absolute highest-quality space-age ear cozies.

That said, Logitech’s older G35s had leatherette to nestle your ears. It’s surprising to see the more expensive G633s step back to a less impressive fabric mesh construction.

Finally, the angle of the trapezoidal cups had me making constant adjustments. Again, it could just be my head, but it could also be a function of the futuristic styling.


I’m an audiophile so, yeah, I’m one of those jerks. My home computer audio rig clocks in around $4k so…$150 headsets aren’t really my first choice in listening devices.

But we’re not comparing $150 cans to $4k worth of pro audio gear, are we? If I did, I’m sure the Logitech crew would come down here and twist my bird-like wrists until I apologized.

The real question is how the G633s stack up to the competition. Again, it’s a story of tradeoffs. If you like the features, then the Logitech sound quality will be plenty fine for you. Because of the ear cup design and mesh material, the bass wasn’t profoundly deep or isolated from the outside world. It was entirely acceptable for gaming headsets in the price range.

I did like the overall tone and voicing of the headset and found it in line with solid engineering, though, again, it’s not trying to be a music headphone. It’s trying to game, game, game.

Speaking of gaming, the speakers boast 7.1 virtual surround which, if you haven’t heard it, isn’t true 7.1. You kinda hear stuff behind you, kinda feel immersed in a game world, but I never had the experience of hearing a zombie about to get all up in my business.

For overall sound quality, the Logitechs aren’t giant killers, and competing music or mastering headphones will sound much better. And rival gaming rigs that run $200-$300 will offer another couple hundred dollars’ worth of sound quality in the form of deeper deeps, higher highs, and all that good audiophile jazz.


So now we’re to the part of the review where Logitech runs the field — features aka buttons aka LEDs everywhere! Yeah, you got that illuminated alien landing strip that runs along the side and the “G” logo with full RGB LEDs that do the typical assortment of pulsing, flashing or whatever you like.

And the G933s link up with Logitech’s arsenal of RGB peripherals, so if you want only pulsing mauve for your cans, keys, and mouse, Logitech has you covered. I did find I had to restart every time I plugged the headphones in to get Logitech’s software to recognize the headphones, but that’s something that will likely be ironed out with further software updates.

The mic is slick. I love the hidy-hole mic style. If you didn’t know this was a gaming headset, you’d be hard pressed to find the mic (but, let’s be real, there’s enough alien plating on this thing to tell anyone you’re a gamer).

First, the mic flips down out of its house. Then the bendy nub end shoots out and twists in whatever direction you like, presumably towards your hate-maker. I couldn’t decide if the extendable mic reminded me of a xenomorph or something tentacled out of a Japanese school girl’s nightmare.

Finally, buttons! Yeah, the custom “G” Buttons along the back of the headset above the volume control. While the volume was useful when my hands were away from the keyboard, I couldn’t figure out a reason why I’d want to be constantly reaching behind my left ear to do anything. Order burrito drone macro? That’d be useful, but I already have that bound to my keyboard.

Maybe there’s some clever use for the three macro keys, I’m sure you’ll figure it out. Although I do worry this ushers in a new age of buttons everywhere. It happened to mice. Are headsets next? Logitech has three buttons, Razer comes out with five, Corsair a dozen, and the button wars are on. But where will it end? Buttons on your face? The future is grim.

Another oddity was the removable side covers. Logitech has clearly marked them for user removal but I’m not crystal about their intended purpose, since whipping them off doesn’t really offer any sort of style or practical benefit. The only thing I could think of was replacing the “G” with your own logo or 3D printing your own covers with team emblems or whatnot. Maybe they’ll be releasing game-specific covers in the future, who knows.


The Logitech Artemis Spectrum G633s are a mixed bag. Despite the marketing hype, the G633s seem to take a step back from the G35s in terms of build quality, materials, and comfort. They up the game with a hidden mic, copious RGB LEDs, and overall style, but I don’t feel that’s enough to absolutely crush the competition…or even the company’s own older headsets.



[ Review ] E-Blue Mazer K727 Mechanical Gaming Keyboard

E-Blue is company that might be as well know as Razer or Logitech but sells a lot of gaming peripherals like gaming mice, keyboards and even gaming chairs. We got the opportunity to test on of their small mechanical gaming keyboards; the E-Blue Mazer K727 Mechanical Keyboard. This is a small compact keyboard that comes with a choice of 4 different mechanical switches: red, black, brown and cyan and backlit keys that can be configured in many ways.

Specifications and Features

The specifications of the E-Blue Mazer K727 Mechanical Gaming Keyboard are as follows:

Dimensions 365×142.5x33mm
Weight 760g
Keys 87
Key lifespan >50 million keypresses
Mechanical Switches Red (also available with black, brown and cyan switches)
Connection USB
Cable 1.8 m braided cable

We actually do not know if this is Cherry MX switches but the image they E-Blue show on their website seems to show Cherry MX-switches so we guess that is what they are (or something similar). Red Cherry MX-switches are not tactile switches. Instead they are linear switches which are not so “clicky” which is what we are seeing.

Diving into the features there are a few nice features we get with the keyboard while missing others.

Backlit keys

In fact, saying “backlit” keys is an understatement since you can do a lot with the lighting of the keys. While not a true RGB-keyboard where you can change the color of each key the keyboard comes with different colors on each row. Red at the top, orange for the numbers-row, blue for the qwerty-row, then green and purple and lastly pink for the space-bar row. In addition to these colors you also get a light blue glow from the bottom of the keyboard.

We will go into this a bit later in the review but there is a bunch of ways you can set up the lighting, some useful and some … not so useful but quite cool.

Full n-key rollover and anti-ghosting

Cheaper keyboards and non-gaming keyboards sometimes do not allow you to press every key-combination without one or more keys not registering. This of course is a disaster if it is the “wrong” combination while you are gaming. The E-Blue Mazer K727 Mechanical Gaming Keyboard have no such issues and in our testing every key worked well even when we pressed them all at one time (with the help of some younger Bjorn3D-trainees).

Floating Keycap design

The keys are raised which gives them a floating feeling. We’ve seen this on for example Corsairs gaming keyboards and it gives the keyboard a nice look and feeling when pressing the keys.

Set response time

It is possible to set the key response time to 2 ms, 4 ms or 8 ms. We must admit we could not really notice a difference but at least it is possible to change.


Amongst the features missing is any kind of macro progrability for the keys. Some of your keys can open things like music player or home page but are only using the settings in your OS.

Closer Look

2015-09-06 19.41.53

The keyboard is available in black or white and we received the white version. This is a small and compact keyboard, very similar to for example the compact K65 Corsair keyboard. It is a so called tenkeyless keyboard which means it does not have the numpad to the right. This makes it compact enough to fit in cramped spaces and also being easier to take with you to a LAN-event.

2015-09-06 19.43.18

The top of the keyboard has a metal finish which actually looks nicer than it might sound. It gives the keyboard a robust and luxurious feel.

2015-09-06 19.42.19

The bottom is plastic and the reason is that that the entire bottom lights up blue when you use the keyboard (this can be turned off of course). One big negative is that there are not stands to be raised so the back of the keyboard can be raised up a bit while typing.

2015-09-06 19.43.10

This is an example of the “floating keycaps”.

2015-09-06 19.43.36

A regular braided cable (1.8 m) is included. Unfortunately there are no USB-passthrough on the keyboard.

Show me the light

2015-09-12 15.57.51

One feature of the  E-Blue Mazer K727 Mechanical Gaming Keyboard is the way you can configure the lighting. While the keys cannot change color you can set the light up a lot of ways. We’ve done a small video of this.

There are several ways you can let the light work. You can for example make it light up the keys like a marquee, let each key light up on keypress or why not the psychedelic effect of having light “ripple” out from the key you are pressing (see the video for this weird (setting). You can also program the keys so only certain keys are lighted up. E-Blue already have a profile for lighting up the WASD + Spacebar but you can do simply whatever you want and it is quite easy. The lights can also be set to a few different brightness levels.

We had several people commenting the keyboard when walking by, something which never has happened. The multi-color lighting is sure to attract attention. Even more important it actually does a great job in making it easier to work in the evening or night in a darker room. The keyboard was especially a hit among children which said it looked like a “Christmas tree”.

Using the E-Blue Mazer K727 Mechanical Gaming Keyboard

It doesn’t really matter if a keyboard looks good or has cool features if it is not nice to work with. In our case we choose to use this keyboard for a couple of weeks both for gaming but also coding and writing.

The Good

This is a really nice keyboard. The feel of the keys are in our opinion really good and we like that the sound is not too loud, something that is useful when typing in the evening when everyone else is sleeping. We also had no issues to get our typing speed up to what we are used to with other keyboards. The light takes a bit to get used to but after a while we really appreciated the ability to have some light in the evening and better see the keys.

Gaming also worked well. You can easily turn off the Windows key so it doesn’t affect your gaming session.

The not so good

We did miss the ability to raise the back of the keyboard up a bit to make it a bit more comfortable to type on. Overall it was ok but for sessions several hours long we got a bit tired in our hands.

The Return-key also was not our favorite. Comparing it to other keyboards it is much smaller while the key just above it is wider than the other keys. We would have preferred it to look like on other keyboards, L-shaped. What basically happened for quite some time before we started to adjust was that we wanted to press Return and instead pressed the button above.


Award_ApprovalEven with the minor issue of the return key and the missing option of raising the keyboard this is actually a really nice keyboard. The keyboard can be bought from www.gearbest.com for $70 and this compares well to other similar keyboards from more know brands, especially since we get full multi-color backlighting. It has a nice solid feel to it and does not fell cheap at all. We’ve used it both for gaming and regular coding and writing and found it both to be confortable and accurate. While the ability to raise the keyboard up a bit as well as a bigger return-key would have been nice it still did not stop us to be very productive with the  E-Blue Mazer K727 Mechanical Gaming Keyboard.

This Review From :


Pros Cons
  • Good quality
  • “floating” keycaps
  • Mechanical switches that does not sound to much
  • Good “feel” to the keys
  • Multi-colored backlit keys with lots of customization options.
  • Compact
  • No programmable keys
  • No way to change color of keys
  • Return-key too small
  • Not possible to raise the back of the keyboard up to improve ergonomics

[ Review ] Logitech G502 Proteus Core Gaming Mouse – review – by Ino

The box is rather small compared to most mice, similar to all the G Series boxes so far. No added

What’s included:
– Logitech G502 Gaming Mouse
– Box with weights
– Warranty, Manual


Box with mouse:

Open box:

Side description:


Box with weights:

Weight & Shape

The shape feels similar to that of the G500, at least from my memory. It is slightly less wide than the EC1 which I’ve put next to it for comparison.

Comparison with G400

I was sceptical about the shape at first, because it looks like those horrible RAT mice, but was rather pleased with the result. The grip I get on it is nice. If it had less buttons and aesthetical stuff on it you could actually see that it has quite the regular dimensions. I don’t know why it looked so big in one of the early pictures from a LAN event, my only guess is that the asian person holding it had very tiny hands.

Weight: 121 g
Height: 40 mm
Width: 75 mm
Estimated width at grip position: 60 mm
Length: 132 mm
Number of buttons: 11

My hand is around 19.5 cm from the tip of my middle finger to the base, I can grip it comfortably without accidentally actuating the forward thumb button.


Thumb rest:

I found the right side of the mouse to be a lot more comfortable than on the G400 for example, mainly due to the missing lip. I will have to do longer gaming sessions to fully evaluate the shape though.

Right side lip:

Of course shape is completely individual preference, so everyone has to try for himself in the end.

Sensor / Performance

The mouse has an all new sensor, the name is still unknown. Logitech promotes it as having a max tracking speed of 7.6 m/s and from my testing so far that could very well be true. No matter how hard I tried, I could not make the mouse malfunction. I tested it at the stock setting without installing LGS (was 2400 dpi for me) and then at 800 dpi. Both performed just perfectly. I have never seen sensor performance like this, it is just perfect in every way for me.

I tried 400, 800, 1800 and 12000 dpi at 1000 Hz which all worked perfectly, then I also tried the other polling rates at my preferred setting of 800 Hz, to my surprise they all offered great results too. There is also no jitter, even at 12000 dpi I wouldn’t call it that, because my movements had to be sooo tiny for those lines and circles that the result is still amazing imo.

The real dpi for each setting can be seen in the mouse tester print, for the lower dpi settings they were very exact and those errors might as well be on my side with the measurement.

Stock setting: 2400 dpi, 1000 Hz

400 dpi, 1000 Hz

800 dpi, 1000 Hz

1800 dpi, 1000 Hz

12000 dpi, 1000 Hz

800 dpi, 500 Hz

800 dpi, 250 Hz

800 dpi, 125 Hz

Jitter test 800 dpi

Jitter test 1800 dpi

Jitter test 12000 dpi

Acceleration Test

As there was a debate wether this sensor has accel or not: It has none for me. I lack the equipment to do a test where I record mouse movement together with the screen, but I did a test in TF2 and recorded that. See video below:

I was swiping over the whole span of my Talent, so ~48 cm.
My settings: 800 dpi, 1000 Hz, in-game sens 0.87 (~60 cm/360°), m_rawinput 1

Lift Off Distance

If you let the LGS calibrate the sensor to your mousepad it will automatically set it to a low LOD, seriously, on my Talent I now have a LOD lower than 1.2 mm (it doesn’t track with 1 CD). So they beat Zowie at that without some lens modification. Also all my test above were done with calibration in place, which should theoretically produce worse results than having a higher LOD. Guess not for this beast.
If you are someone who does not want a low LOD you should probably switch to the standard calibration for the sensor.

Buttons / Switches / Scroll Wheel

The main buttons have a nice click feeling, they seem very well balanced in actuation force. I did not accidentally misclick yet, unlike I did on the Deathadder back in the day. They need less force than the buttons on any Zowie. The buttons to the side of the left click (dpi change by default) feel worse, but only a bit.

The switches for the main buttons seem to be all Omrons D2FC-F-7N

(Picture by blackmesatech)

The Scroll wheel is my only gripe with the mouse, as it is rather heavy and also wobbles when in free scroll. It works just fine though, I just don’t like the feel. Coming from a 16 notch Zowie wheel that probably was to be expected.

Build Quality

The cord is braided, but very flexible. I personally don’t like braided cables, but this is the best braided I’ve seen so far. Comparable to the Zowie cables in terms of flex.

Overall Build quality is good, everything seems to be high quality. The wheel wobbling slightly in free scroll is probably due to the way the mechanic works and because it’s a tilt wheel.


The sensor that Logitech has introduced with the G502 Proteus Core kills all competition if you ask me. I’ve never been this satisfied with a sensor like this. There are some downsides for my personal preference as I’d rather like a smaller, lightweight, ambidextrous mouse, but if you want a full on palm mouse with lots of buttons this would be the one I would recommend to everyone. The weight might be an issue if you are a low sens player like me, because 121 g for a long gaming session can get tiring.
So I really hope to see this sensor in the upcoming Logitech releases, seeing how much they have invested to come up with a sensor like this I have no reason to believe this isn’t going to happen. This sensor in a shell similar to the Sensei or the Zowie FK would be the best mouse I can imagine.

[ Review ] Steelseries Sensei Wireless

Most advanced users, especially those that are interested in gaming, have almost certainly heard of SteelSeries, a reputable manufacturer of gaming-related peripherals and hardware. The company originates from Denmark and today has offices in the US and Taiwan. They have a very large selection of products available and we cannot possibly cover them all in a single review, but today we will be having a look at their most advanced (and expensive) mouse, the Sensei Wireless.

We received the Sensei Wireless inside a simple, well-designed, hard cardboard box, which should offer ample shipping protection to the lightweight mouse. Aside from the mouse itself, the only other items inside the box are the dock, the USB cable, a company sticker, and a basic manual. There is no CD with the required software, which instead must be downloaded from the company’s website.


The SteelSeries Sensei Wireless Mouse

The SteelSeries Sensei Wireless is a symmetrical mouse of classic design. It is a good choice for left handed or ambidextrous users and very comfortable for prolonged use, although perhaps not as ideal as ergonomic mice that are shaped to fit either the left or the right hand. For instance, the Sensei Wireless has two buttons on either side of the mouse. Two of these buttons can easily be pressed by a thumb but it is painfully frustrating to press the other two with your pinky or ring finger. The ribbed wheel of the mouse offers good feedback and comfort, without being too stiff or too soft. There is only one button at the top of the Sensei Wireless that, if not re-programmed, can be used to cycle through the CPI settings.

The top and sides of the SteelSeries Sensei are made of corona treated (“rubberized”) plastic, which feels comfortable to the hand and improves adhesion. The company logo can be seen at the top part of the mouse, which illuminates once the mouse is powered on. You can even pick the illumination color and intensity through the software, as well as select from a couple of visual effects, such as “breathe” and “battery status”. The default colors of the mouse are red and it is set on “breathe”, but these can be easily changed to virtually any color combination and intensity possible.

Perhaps the most interesting feature of the Sensei Wireless is its metallic charging dock. The heavy dock has a metallic surrounding frame but its central and bottom parts are plastic. It is heavy enough so that it won’t slide around on your desk and it’s shaped to be a perfect fit for the mouse. It also acts as the wireless receiver, but unfortunately the fact that the wireless receiver is integrated into this large, heavy, metallic dock reduces the portability of the Sensei Wireless down to virtually zero, at least if you want to use it in wireless mode. An illuminated ring surrounds the dock, which can also be programmed via the software.

The cable that SteelSeries provides can be connected to either the charging dock or the mouse itself. This way, if you run out of battery, you can just connect the cable to the mouse and keep playing. The proprietary molding of the cable is a perfect fit for either the mouse or the dock. The connector will lock into place once attached to the mouse and you’ll need to be careful and not forget about the unlocking button when removing it, as otherwise it is easy to cause permanent damage. There is a catch too; due to the proprietary shape of the connector, finding an exact replacement will be a pain should you lose or damage yours. A typical mini USB cable will fit into the dock but it will not really be a good match for the mouse.
