Since the Corsair Void Pro RGB USB is so similar to the Void Pro RGB Wireless, I'll reiterate some of the things I already covered in its review. Of course, we'll also check out the features unique to the Void Pro RGB USB.
Corsair's headsets always looked a bit odd, mainly because their ear cups weren't oval or round. That's because they did their best to follow the natural shape of ears. Aesthetics-wise, you might or might not like them, but as far as ergonomics go, it's impossible to say anything bad about them as the ear cushions surround the ears completely.
The ear cups are attached to joints that allow them to be rotated by 90°, making it easy to rest them on your chest or on top of the table.
They can also be flexed in various directions. Thanks to that, they have the ability to completely adjust to anyone's head. At the same time, you won't have to worry about them breaking if they accidentally land on the floor, which could indeed be a risk if they were made rigid.
To make the ear cushions, Corsair went with a combination of a viscoelastic memory foam and microfiber mesh fabric. The result are superbly soft, comfortable, and breathable ear cushions that don't seem like they could start showing any signs of wear in the foreseeable future. They don't press up against the sides of the head strongly. You might even consider the clamping force to be loose. If you quickly shake your head, moving it from left to right, the headset will definitely fall off. Some could see that as a problem. I have to admit that I don't as normal people don't vigorously shake their head while gaming, do they now?
As far as built-in controls go, the outer part of the left ear cup contains a microphone mute button, and there's a multipurpose jog-dial on its bottom side. A short press of the button will mute the microphone - duh! - and a long-press activates and deactivates the microphone sidetone (microphone monitoring) function. It sends the sound captured by the microphone into the headphones. That way, you can hear your own voice as you would when using an open-back pair of headphones. It will prevent you from shouting or sounding nasal. The microphone sidetone's volume can be controlled in the Corsair Utility Engine. A pleasant voice will tell you when you've muted the microphone (there's also a stripe with a red LED on the microphone's arm to inform you of it) and activated the monitoring function (the voice calls it "mic feedback").
The main purpose of the jog dial is to digitally control the volume. Pushing it upward increases it, while pulling it downward causes it to decrease. As soon as you let go of the dial, it will spring back into the middle position. It can also be pushed inward and act as a button. A short press will switch between sound profiles (equalizer settings) that are configured within the Corsair Utility Engine. You can have up to five of them active at once. How will you know which one you're currently using? By listening to the number of beeps or the number mentioned by the voice prompt. Sadly, this "voice assistant" is unable to pronounce the names of these sound profiles even if you stick with the default ones, so you'll just hear "one", "two", "three", "four" and "five" instead, which forces you to remember which exact profile they correspond to. A long press of the jog dial will activate or deactivate Dolby Headphone:X 7.1 Surround Sound.
In case you were wondering about the RGB capabilities of the Void Pro RGB Wireless, you'll be interested to find out that the lighting effects are limited to the Corsair logo on left and right ear cups. It can be lit up in a static color and a blinking, breathing, or rainbow effect. In most of those cases, the exact colors are, of course, user-selectable.
The microphone arm is rubberized and made in a way that has the head of the microphone always position itself at an optimal distance from the mouth; it also comes with a nice windscreen.
As previously mentioned, the cable terminates in a USB plug. There's no way to connect the Void Pro RGB USB to a device that only supports analogue audio connection.
