Review: Logitech G633 Artemis Spectrum headset

The Logitech G633 Artemis Spectrum brings the heat with impressive sound, excellent design, LED lighting, customization options, and virtually every headset feature you could ask for. To date, the G633 is one of the best PC gaming headsets you can own.

 The Artemis Spectrum headsets (G633/G933) replace the Logitech G930 as Logitech’s flagship PC/cross-platform headset. (The G933 is the wireless version of the G633.)

The G633 combines top-notch audio quality powered by Dolby and DTS HeadphoneX surround sound technology with a robust software-powered feature set.

The G633 also has customizable LED lighting and removable ear cup face plates you can replace with after-market customizable face plates if you’re so inclined.

Comfort and design

With 1”thick cloth-covered memory foam lining the ear cups, the G633 is very comfortable and provides a good level of noise cancellation. However, they don’t grip your head as firmly as some headsets. This is a slight trade off in comfort vs. audio characteristics—i.e. a tighter fit seals out external distractions a little more. The G633’s actually slid off my head a couple times mid-game (my hair was at least partially the culprit there), and I only had to re-adjust them slightly on my head for a better fit. (They stayed put after the adjustment.

Logitech’s LED light strips and removable ear cups add some bright, snazzy accents if you’re partial to such. They aren’t particularly useful, but they look nice, and you can swap out ear plates for a custom look—if you can find any.

The noise-canceling unidirectional microphone folds seamlessly into the headset for a streamlined package. The mic also auto-mutes when it’s raised, but if you opt to mute it manually using the mute button just above the volume control, a red LED on the tip of the mic lights up to let you know it’s muted. It did its job well in games of Smite and the (currently closed) beta of Blizzard’s Overwatch.

Although I don’t like the button and volume placement on the G633 as much I as a like that of the G930, I still like it better than a typical inline remote. And the buttons are sculpted (they have slightly different shapes) for easier identification.

More importantly, I’ve always preferred a volume wheel/roller controls to volume +/- buttons (which are all too often nigh indistinguishable from other buttons on many headsets), and the G633 keeps this feature, even if it locates in a slightly less convenient location.

It’s Logitech’s ergonomic, design, and usability refinements present on the G633 as well as their keyboards (like theOrion Spark keyboard) and mice (like the Proteus Core) that often lead me to prefer Logitech gaming gear over others.


The G633 boasts better sound quality than the G930—and some of the best overall sound quality in a PC gaming headset, period. The G633 delivers powerful bass (great for the big booms), excellent clarity, and possibly the best virtual surround sound I’ve experienced in a gaming headset.


True, headphone virtual surround is never quite as good as a dedicated 7.1 speaker setup, but the G633 comes about as close as I think you could get with a set of headphones, thanks to the software powered by both Dolby and DTS HeadphoneX. The virtual sound field sounds much ‘bigger’ than you think it should, and the directional audio is distinct—although the 3 rear channels do blend a bit more and seem a little less distinct than the front channels. (The quality of the surround sound was excellent in Left 4 Dead 2, a game that makes ample use of surround sound and audio cues.)

Logitech’s Gaming Software provides an equalizer with plenty of presets and the ability to tweak sound settings to your own preferences. You can also program the 3 of the 4 buttons to do virtually anything you want—from simple preset functions like profile switching to media controls to (if you wanted to for some strange reason) macros comprised of mouse and keyboard commands. Too bad they haven’t figured out how to make the mute button work on your pets yet.

I was a little surprised Logitech’s Gaming Software for the G633 no longer includes voice alteration FX. No, it’s not a big deal. But It was fun to sound like a chipmunk sometimes in games and audio conferences…

Overall: Highly recommended

The Logitech G633 Artemis Spectrum combines outstanding audio quality, Logitech’s fine attention to detail, design, and usability characteristics, and robust software features to make it one of the best PC gaming (and cross-platform) headsets you can own.


  1. These headphones, albeit decent. Have flaws that don’t appear until months of use. Such as build quality. These are made like crap so all these positive reviews about build quality are a lie. I had to replace them 2 times. Im not an audiophile but i can tell you for a fact that these things are being held by back by their 40mm drivers and their shitty software. Also the sound stage for these is very, I want to say narrow. So its not going to sound as good as a headset such as the philips SHP9500 as these things are easily 170$ or at least what they should cost.
    Anyway these aren’t bad but theyre just a typical gaming headset. What you should come to expect, Garbage.

    1. I haven’t had those problems, but one thing I did notice more i
      after extended use is that they were prone to fall of my head more easily than some headsets – – something I mention in my (upcoming) review of the G533.
