With a price tag of $400, the Pro X Wireless should deliver an exceptional audio experience. It very much does. Twin Logitech Pro-G 50mm drivers create a powerful soundscape in games, music and movies. From crisp highs to massive, skull-rattling bass, the overall audio quality is simply impeccable.
In Destiny 2, for instance, the powerful bass added a physical kick each time I pulled the trigger of my submachine gun. With the volume pumped up, it felt like I was sitting next to the double bass drum of a high-speed metal band.
Higher-frequency sounds are similarly impactful, though only after a little tweaking. Out of the box, the Pro X Wireless is configured to prioritise bass to the detriment of treble. This produces a sound I found muddy, causing softer audio sources to bleed together. Fortunately, a quick adjustment of the EQ was all it took to achieve a more balanced mix. With those adjustments, the whistle of an unleashed combat bow and the crack of a fusion rifle cut through the audio mix with a satisfyingly sharp edge that emphasises their lethality.
Gears 5 further exemplifies the audio capabilities of the Pro X Wireless. Firing the Gnasher shotgun produces a booming retort that echoes through the skull, while the rattle of the Talon autopistol shears the air with vicious force. Smaller yet equally powerful sounds complement these moments of bombast. The clink of an ejected magazine hitting the ground punctuates a moment of brief respite between enemy waves. Heavy breathing from my teammates reminds me that they're right behind me, fighting as feverishly as I am.
Excellent positional audio plays a key role in how good the Pro X Wireless sounds. Along with offering virtual 7.1 surround sound, Logitech has partnered with audio technology company DTS to incorporate DTS Headphone:X 2.0. A positional audio solution that claims to "go beyond 7.1", DTS Headphone:X 2.0 promises more precise audio cues that capture elevation in addition to cardinal information. Unfortunately, support for DTS Headphone:X 2.0 is severely limited, with only a handful of games currently taking advantage of the technology.
That doesn't really matter, though, because the regular 7.1 surround sound implementation is top-notch. In games like Destiny 2, Rage 2 and Gears 5, each sound conveys distance and direction, producing an expansive audioscape that enhances situational awareness while heightening the sense of place within the game world. Channel separation is solid, maintaining clarity as explosions compete with the rat-a-tat-tat of assault rifles and the avalanche of approaching footfalls.
One of the few areas where the Pro X Wireless lags behind the competition is volume output. Its surround sound is noticeably quieter than many other headsets, never reaching ear-splitting levels even with the volume cranked all the way up. You'll want to crank the volume, too, as the Pro-G drivers don't unleash their full potential until you hit around 70%. In the games I tested, anything below 70% lacked punch, especially across high frequencies.

The other side to gaming headset performance is mic audio. Here, Logitech has teamed up with Blue Microphones, makers of the popular Blue Yeti USB microphones, to incorporate Blue Vo!ce technology (hereafter referred to simply as Blue Voice) into the Pro X Wireless.
Activating the Blue Voice toggle in the Logitech G Hub app applies a wealth of software-based filters to your voice, each of which you can customise to an almost-overwhelming extent. Not that you need to, as simply selecting any of the preset profiles has a significant impact on mic quality.

Along with greatly reducing hissing, peaking and other vocal noise, the presets add a warm body to your voice, conveying a fuller, more professional sound. Not only does this result in a better audio experience if you're streaming out to an audience, it makes it easier for your teammates to hear you over their in-game audio. And if you can't find the right sound with the built-in presets or the many user-made configurations available for download, the myriad individual filters (detailed in the Features section below) should provide more than enough flexibility for most needs.
Connectivity can make or break any wireless gaming headset. Logitech clearly understands this, as it has equipped the Pro X Wireless with its custom Lightspeed wireless technology. It works just as well here as it does on the Logitech G915 wireless gaming keyboard, which is to say it's flawless. I experienced no noticeable interference or connection hiccups throughout my testing, and the 15m effective range meant I could walk around my house without losing connection.
Last on the performance docket is battery life. Logitech touts 20+ hours with the volume set to 50%, but I was able to eke out a smidge over that even with the volume sitting above 70% for the majority of my testing. As such, I suspect you could probably squeeze a few more hours out of the battery at lower volumes. You can also set an automatic timeout for the Pro X Wireless to turn itself off when inactive, which helps to save battery during intermittent use.
