Logitech G Pro X Wireless Lightspeed Review

Logitech's gaming division is no newcomer, but here it delivers its first wireless headset equipped with Lightspeed technology, alongside Blue Vo!ce, the processing software meant to improve microphone quality. This is the wireless version of the Pro X — does it keep all its promises? This review is based on that published test, not on a hands-on trial of our own.

The Pro X Lightspeed is practically identical to its wired counterpart. What sets it apart first are the controls, all on the left earcup: a power switch, a volume wheel, a microphone mute button and a USB-C charging port. Less obvious out of the box, the earcups are noticeably deeper — by a good two centimetres — to house the battery and wireless transmitter, though their height and width, and the headband and yoke dimensions, are unchanged. The Pro X was already a fairly imposing headset, if less so than a Sennheiser GSP 670, and the yoke construction inevitably adds some bulk. That is no real problem for a headset designed to be used at a PC, but the ergonomics are lesser than on models with earcups that pivot vertically: the Pro X Lightspeed does not sit easily around the neck during a break. The extra weight of the battery is felt on the ears, too; at 370 g the headset makes itself known, especially after several hours of play. Overall, though, comfort is there, the padded synthetic-leather headband balancing the pressure well, with a very good hold and plenty of adjustment. Cutting the cable is welcome — the wired version's 2 m lead drags on the floor and can be trodden on or even yanked out mid-game. Only the microphone windscreen changes, taking a slightly more elongated shape; finishes are excellent, the two chromed discs still look the part, and the bundle includes a USB-A to USB-C charging cable, a set of fabric earpads (cooler than the synthetic-leather pair), the Lightspeed USB receiver and a fabric carry bag.

Logitech has made the Pro X Lightspeed work solely over its 2.4 GHz RF link: there is no Bluetooth and no 3.5 mm mini-jack, only the "Pro X Wireless DAC" USB receiver, with no alternative. Even plugged into a PC by its charging cable, the headset will not play — the wireless DAC animates it or nothing does. That is a shame, since, unlike the wired version, it cannot be used with consoles, phones, tablets or televisions; only PS4 players get anything, and only in stereo, without the DAC and G Hub benefits. PC players, though, enjoy rich G Hub customisation of voice capture, acoustics, surround and per-game settings. The payoff for that single connection is a genuinely strong wireless experience. Logitech quotes 20 hours of continuous use on a full charge (measured at 50% volume); in practice, rarely above 80% volume, the battery lasted close to 18 hours, and USB-C charging is fast, 15 minutes yielding 60%. Connectivity is arguably the headset's greatest strength: as the first wireless Logitech headset to carry Lightspeed — already proven on the G915 keyboard and G502 mouse — it showed no latency or instability, with a 13 metre range easily covering a whole home, the signal only dropping outdoors.

Where many wireless headsets struggle, the Pro X Lightspeed excels: the published test found little difference from the wired version and no parasitic noise. It is a balanced, pleasant listen, with punchy but restrained bass that is noticeably tighter with the fabric earpads — isolation suffers a little, but shooters and racing games gain clarity. Music playback is decent across most styles, if electric guitars can sound a touch aggressive. It is in games that the headset shines, thanks largely to DTS Headphone:X v2.0 surround: the soundstage widens usefully, a clear competitive edge in a game like Call of Duty for pinpointing enemies from footsteps and gunfire, and a boost to immersion elsewhere, from engine roar in Dirt 2.0 to rain in Death Stranding, even if it does not match the 3D precision of a headset like the Mobius. The microphone is the clear step back. Blue Vo!ce is still present with its wealth of settings, but the capture is markedly less convincing than the wired version's, which ranked among the best in its class: the voice is compressed, less natural and short on clarity, with distortion if it runs too hot or too close. It is not a bad microphone — capture is intelligible — but it sounds artificial, and it is worth tweaking the settings or simply switching Blue Vo!ce off. The sidetone remains useful, and the cardioid capsule filters ambient noise fairly well, with a noise-reduction control to refine things further.

As the first Lightspeed headset, this model keeps most of its promises and goes no further than what it sets out to be: a wireless version of the excellent Pro X. That is both its strength and its weakness, for the wired Pro X offers a complete, versatile experience this version struggles to match, held back by its single connection and a less appealing microphone. It is by no means a bad headset — far from it — but the question is whether a headset used at a computer should cut its cable at the cost of a higher price, 50 g of extra weight, a step back in voice quality and a single connection that ties it to a PC (or PS4). Are you ready to make those compromises for the sake of losing the cable? Solid, comfortable and blessed with convincing surround and software, the Pro X Wireless Lightspeed makes a good showing, but it lacks connection options and suffers by comparison with its wired sibling.
