The G633 Artemis Spectrum is a full-sized circumaural gaming headset. What should stand out is its size. While it is not the heaviest gaming headset we have reviewed, the earcups are hefty and thick to accommodate the electronics.
The foldable microphone is the only big business going on the front of the headset. Looking elsewhere, Logitech has put RGB light zones, volume control wheel, and the G-Keys on the back. While the placement of these controls may not appear to be an intuitive, it was easy using the left thumb to adjust the volume. It took a bit longer to remember the feel of the shape of the three individual G-Keys and they’re stiff enough that the entire earcup has to be held to press those buttons. By putting RGB LEDs on the back of the headset, the lighting is visible to others people standing around.
The tip of the microphone boom is also retractable and can be bent to adjust the pickup pattern. Muting the microphone from either system volume or the button on the headset turns on a red LED indicator on the tip of the boom.
The G633 comes with two cables: a 5 ft. (60 in. / 1.5 m) braided 4-pole 3.5mm cable and a 9 ft. 10 in. (118 in. / 3 m) long USB-to-microUSB cable. On the bottom of the left earcup are jacks for these cables. A sliding switch on the same earcup controls which jack receives the input.
The 3.5mm analog cable has an inline microphone and controller with a clip placed 6 inches from one end. It has a built-in volume control wheel that works independently of the source, a play/pause button for mobile devices, microphone mute, and a switch for choosing either the headset microphone or the inline microphone.
