Logitech G733 LIGHTSPEED Wireless Gaming Headset Review UK 2026

In competitive gaming, the margin between a successful read and a fatal mistake often comes down to milliseconds of audio information. Whether you process an enemy's positional cue before they've committed to their push isn't luck; it's a direct function of your headset's imaging accuracy, latency characteristics, and frequency response. That's the analytical lens I apply every time I strap on a new headset, and it's the same lens I've used across several weeks of testing the Logitech G733 LIGHTSPEED Wireless Gaming Headset.

The G733 sits in Logitech G's upper mid-range wireless lineup, competing in a bracket that demands genuine audio performance rather than spec-sheet theatre. It's a headset that makes a statement before you even put it on: the colourful aesthetic, the front-facing RGB lightstrip, and the suspension headband all signal that Logitech is targeting a specific kind of gamer here. But aesthetics don't win firefights. Over several weeks of testing across Valorant, Warzone, and single-player titles, I've put this headset through its paces in the scenarios that actually matter.

The bottom line upfront, because that's how this review works: the G733 is a genuinely good wireless headset at its price tier, with strong LIGHTSPEED wireless performance and comfortable long-session wear, but it makes some compromises in audio accuracy that more analytically-minded players will notice. Here's the full breakdown of why.

There's no 3.5mm analogue output on the G733, which is a deliberate design choice that limits its compatibility in certain scenarios (more on that in the Connectivity section). The headset charges via USB-C, which in 2026 is the minimum acceptable standard and Logitech deserves credit for not shipping a proprietary charging cable. Logitech rates battery life at 29 hours, and the earcups use a memory foam construction with a fabric covering rather than leatherette or pleather.

The microphone is a cardioid boom mic that flips up to mute, which is a simple and effective solution. There's no dedicated mute LED indicator visible from the front, which is a minor annoyance during streaming or group calls when you want a quick visual confirmation. The headset also features a front-facing RGB lightstrip on the headband, which is either a selling point or irrelevant depending on your perspective. It does draw from the battery, though Logitech's G HUB software lets you disable it entirely.

The microphone's frequency response is specified at 100Hz to 10kHz, which is narrower than the headphone drivers. That upper limit of 10kHz means some of the air and presence frequencies in speech are rolled off, contributing to the slightly muffled character I measured during testing. For voice communication in gaming, this range is adequate, but it's not going to produce broadcast-quality audio. The cardioid polar pattern does a reasonable job of rejecting off-axis noise, which I'll cover in more detail in the microphone section.

One thing worth understanding about the G733's audio chain is that all processing happens digitally through the LIGHTSPEED dongle and G HUB software. There's no analogue signal path available, which means the headset's performance is entirely dependent on your PC's USB implementation and the quality of Logitech's DSP. In practice, I measured no perceptible latency issues during gaming, and the digital chain keeps the noise floor very clean. But it does mean you're locked into the Logitech ecosystem for any EQ or processing adjustments, which has implications for console users in particular.

The bass elevation is centred around the 80-100Hz region, giving kick drums and low-frequency game audio a satisfying weight. In story-driven games like Cyberpunk 2077 or Horizon, this works well; the soundscape feels full and immersive. But in competitive titles, that bass emphasis can mask some of the lower-mid frequency content where footstep sounds and environmental audio cues tend to live. It's not a dealbreaker, and the G HUB EQ lets you flatten things out, but out of the box you're getting a consumer-friendly tuning rather than a competitive one.

The treble response is boosted in the 6-8kHz region, which adds perceived clarity and crispness to high-frequency sounds like reload animations and distant gunfire. This can actually be useful for competitive play, helping certain audio cues cut through. But it does mean the G733 can sound slightly fatiguing over very long sessions if you're sensitive to upper-frequency emphasis. I noticed this during a particularly long Warzone session, around the four-hour mark, where I found myself reaching for the volume control more than usual. Switching to a flatter EQ profile in G HUB resolved it, but it's something to be aware of.

The virtual surround mode, accessed through G HUB, is the usual story with software-based spatial audio: it widens the perceived soundstage at the cost of imaging precision. I tested it extensively in Warzone and found that while it created a more dramatic sense of space, the actual accuracy of positional cues degraded compared to stereo. This is consistent with my experience across dozens of headsets over eight years. Virtual surround is a marketing feature. For competitive play, stereo mode is almost always the better choice, and the G733 is no exception.

For music and movies, the G733 performs well above its station. The bass extension is genuinely good for a closed-back wireless headset, reaching into the sub-bass region with reasonable authority. Treble detail is present without being brittle. Midrange is the weakest link, as you'd expect from a V-shaped tuning; vocals and acoustic instruments sit slightly behind the mix. But for gaming soundtracks and cinematic content, the overall presentation is engaging and enjoyable. I spent several evenings watching films through this headset and had no complaints about the experience. It's a headset that does entertainment well, even if it's not a flat reference monitor.

I ran several recording tests using Audacity, capturing voice samples at various distances and comparing them against the SteelSeries Arctis 7+ and the HyperX Cloud Alpha Wireless. The G733's mic was consistently the least detailed of the three, with a noticeable roll-off above 8kHz that strips some of the natural presence from speech. Background noise rejection was reasonable in a quiet room but struggled more than the Arctis 7+ in noisier environments. The Blue VO!CE software processing available in G HUB does help; enabling the noise gate and the high-pass filter cleaned up the recording noticeably, and the compressor helped even out volume levels.

The flip-to-mute mechanism is one of the better implementations I've tested. The action is positive and deliberate, with a satisfying click that gives you tactile confirmation the mic is muted. There's no accidental muting from casual head movements, which has been a problem with some other flip-mic designs. The boom arm itself is flexible and holds its position well; I set it once at the start of testing and didn't need to readjust it. For the target audience of this headset, which is primarily gaming communication rather than streaming or content creation, the microphone is perfectly adequate. If you're planning to stream, you'll want a dedicated USB microphone.

The earcup padding uses memory foam covered in a soft fabric material rather than leatherette. This is a deliberate choice that improves breathability significantly; after two hours of gaming, the leatherette cups on competing headsets are noticeably warm and slightly sweaty, while the G733's fabric cups remain comfortable. The trade-off is passive noise isolation, which is lower with fabric than with leatherette. In a quiet room this doesn't matter, but if you're gaming in a shared space with background noise, you'll notice more bleed-through. The earcups are also replaceable, which is a nice touch for long-term ownership.

Build quality is solid without being exceptional. The plastic construction feels durable and the hinges have a smooth, controlled movement. But it's clearly a plastic-dominant build rather than the metal-reinforced construction you'd find on headsets at the top of the price bracket. The headband arms flex slightly under pressure, which is fine in normal use but suggests the G733 wouldn't survive being sat on or dropped repeatedly. The RGB lightstrip on the headband is integrated cleanly and doesn't feel like an afterthought. Glasses wearers should note that the fabric earcups are more forgiving than leatherette for extended wear with frames, though the clamp force is moderate and some glasses temples may still cause discomfort over very long sessions.

The dongle is a small USB-A receiver. There's no Bluetooth option on the G733, which is a notable omission at this price point. Competing headsets like the SteelSeries Arctis 7+ offer simultaneous 2.4GHz and Bluetooth connectivity, letting you connect to your PC and mobile device at the same time. The G733 is LIGHTSPEED only, which means if you want to take a phone call while gaming, you're either pulling the dongle out or going without. For dedicated PC gamers who don't need multi-device pairing, this isn't a problem. But it's a real limitation if you want flexibility.

There's also no 3.5mm analogue output, as mentioned in the specifications section. This means the G733 cannot be used as a passive wired headset when the battery dies, and it cannot connect to devices that don't support USB. On PC this is fine. On console, it limits you to PS4 and PS5 via the USB dongle, and it means the headset is completely incompatible with Xbox consoles (which don't support the LIGHTSPEED dongle) and Nintendo Switch in handheld mode. The USB-C charging port is for charging only, not audio output. These are deliberate design decisions that keep the wireless chain clean, but they do narrow the headset's versatility.

Charging via USB-C is straightforward, and Logitech's documentation suggests a full charge takes approximately three hours. I found this accurate in testing. There's no fast-charge feature that I could identify, so if you run the battery flat before a session, you're waiting the full three hours. Some competing headsets offer a quick-charge function that provides several hours of use from a 15-minute charge; the G733 doesn't have this, which is a minor but real omission. The battery level is displayed in G HUB software, and there's an audible low-battery warning tone that plays through the headset when charge drops to a critical level.

One thing I tested specifically was battery performance with the virtual surround processing enabled, since DSP processing can draw additional power. The difference was marginal, around one to two hours less than stereo mode, which suggests Logitech's power management handles the processing load efficiently. Overall, battery life is one of the G733's stronger points. It's not the longest-lasting wireless headset I've tested (that distinction goes to headsets claiming 40+ hours), but 29 hours is more than sufficient for real-world gaming use, and the USB-C charging means you're not hunting for a proprietary cable.

The EQ section offers a parametric equaliser with multiple bands, which is more flexible than the simple preset-based systems on some competing headsets. I used this extensively to flatten the G733's V-shaped default tuning for competitive play, and the results were genuinely useful. The mic section includes Blue VO!CE processing, which Logitech acquired through its purchase of Blue Microphones. This gives you access to noise gates, compressors, high-pass filters, and some voice effects. It's more processing power than most gaming headset software offers, and it meaningfully improves the microphone's output quality when configured correctly.

RGB customisation is handled through G HUB's lighting section, where you can set static colours, breathing effects, or sync the lightstrip to in-game events through Logitech's LIGHTSYNC system. The G733 comes in several colour variants (black, white, lilac, and blue), and the RGB lightstrip can be set to complement or contrast with the headset's physical colour. For those who care about this sort of thing, the customisation is thorough. For those who don't, you can disable the RGB entirely and recover some battery life. Firmware updates are handled automatically through G HUB when the headset is connected, which is convenient and means you're always on the latest version without manual intervention.

On PlayStation 4 and PlayStation 5, the LIGHTSPEED dongle connects via the console's USB ports and the headset functions as a USB audio device. You won't have access to G HUB's EQ or mic processing on console, but basic audio and microphone functionality works. Sony's own Tempest 3D audio on PS5 is compatible with USB headsets, so you can use the PS5's spatial audio processing with the G733. On Xbox Series X/S and Xbox One, the headset does not work. Microsoft's wireless audio standard is incompatible with LIGHTSPEED, and without a 3.5mm output there's no fallback connection method. This is a hard limitation.

Nintendo Switch compatibility is partial. In docked mode, the USB dongle can connect to the Switch dock's USB ports, and the headset functions as a USB audio device. In handheld mode, the Switch's USB-C port can theoretically support USB audio adapters, but the G733's dongle is USB-A and requires an adapter. The headset has no 3.5mm output, so handheld Switch use is effectively not supported without additional hardware. For mobile use, the lack of Bluetooth means the G733 won't connect to smartphones or tablets at all. If you're a multi-platform gamer who moves between PC, console, and mobile, the G733's connectivity limitations are a genuine consideration.

In audio quality, the three headsets are closely matched. The Arctis 7+ has a flatter default tuning that I find more useful for competitive play out of the box, while the Cloud Alpha Wireless has a slightly warmer, more musical character. The G733 sits between them with its V-shaped consumer tuning. Microphone quality is broadly similar across all three, with the Arctis 7+ having a slight edge in voice clarity in my testing. Where the G733 wins is comfort, particularly for long sessions, where the suspension headband design outperforms the traditional padded bands on both competitors. Build quality is comparable across the three.

The G733 is competitively priced within this bracket, and when you factor in the LIGHTSPEED wireless performance, the Blue VO!CE mic processing, and the genuine comfort advantage of the suspension headband, it represents solid value. But if you need Bluetooth connectivity, the Arctis 7+ is the more versatile choice. And if battery anxiety is a concern, the Cloud Alpha Wireless's dual-battery system is hard to argue with. The G733 is the right choice if you're primarily a PC gamer who values comfort and wireless reliability over multi-device flexibility.

The compromises are real, though. The V-shaped sound signature requires EQ adjustment for competitive use, and the lack of Bluetooth limits multi-device flexibility. The microphone is functional but not impressive, and the absence of a 3.5mm output means you're committed to the LIGHTSPEED ecosystem with no fallback. For a PC-primary gamer who plays a mix of competitive and story-driven titles, values comfort above all else, and doesn't need to pair with a phone or tablet, the G733 is a strong choice at its price point. It's not the most analytically precise headset in this bracket, but it's one of the most liveable.

If you're a dedicated competitive player who wants the flattest possible frequency response and the sharpest imaging, you'd be better served by the Arctis 7+ with its more neutral default tuning. If you're an Xbox gamer, the G733 simply won't work for you. But for the PC gamer who wants a comfortable, reliable, good-sounding wireless headset with strong software support and a bit of personality in its design, the Logitech G733 delivers. I'd score it 7.5 out of 10: a genuinely good headset held back from greatness by its connectivity limitations and consumer-tuned audio signature.
