Logitech G733 LIGHTSPEED Wireless RGB Gaming Headset

Battery life and lighting

Logitech claims 29 h with lighting off at 50% volume, and 20 h with default lighting. SoundGuys measured 28 h 26 min at a constant 75 dB with the LEDs off, and Tom’s Guide saw a discharge rate consistent with the same figure, so the lights-off claim holds up.

Lighting is where the budget goes. Tom’s Hardware ran it 6 h at 100% brightness and G HUB still showed 66%, which works out to roughly 15 h. PCWorld had 24% left after 15 h with RGB on, closer to 19 or 20 h, and IGN reported it beating the 20 h claim at half volume. Treat anything with lights on as mid-teens to about 20 h. Android Central put the loss to lighting at roughly 9 h and called it disappointing. Auto-shutoff is 30 minutes of inactivity by default and drops to 1 minute or off.

Owner reports split. One owner says daily use has been much better than advertised, and another measured a little under 10% an hour after a year. Against that, r/LogitechG threads report a headset that never held a charge past 3 h and never warned before shutting down, a G HUB battery reading stuck at charging, a replacement pair that stopped at 7%, and a percentage that stayed wrong through a device reset and a reinstall. The community answer in one of those threads is to charge it overnight, run it flat once, expect about 20 h with lighting and closer to 30 h without, and ignore the percentage. Nobody has published a failure rate, so read this as a known annoyance rather than a measured defect.

Sound and the microphone

SoundGuys measured a very accurate response across the spectrum, with bass slightly low against its house curve, and RTINGS called the default profile well balanced but lacking bass. IGN found it clean and loud with no leaning toward treble or bass. Audio delivery is sensitive to seal and positioning, so the sound shifts a little between wears.

The microphone is the most cited weakness. SoundGuys scored it 6.7 out of 10: clear, but with a large bass and midrange dropoff up to around 500 Hz. RTINGS heard a voice that is clear but not natural or full-bodied, doing a decent job of separating itself from room noise. Hardware does part of the damage, because the boom is a 6 mm stick with no telescoping arm and no mute indicator light. Tom’s Hardware’s teammates said it sounded muddy or nasal with Blue VO!CE defaults on. The counterweight is Blue VO!CE itself, which SoundGuys said improves the mic noticeably and adds presets, EQ, compression, gating and filtering. Manufacturer spec is a cardioid 100 Hz – 10 kHz boom, Discord-certified.

The surround modes split the testers. IGN liked the directional cues in Overwatch and Fortnite, but said enabling Surround Sound blew out the bass and did not return to normal through customization.

Fit, comfort and isolation

At 278 g this is one of the lighter headsets testers have handled, and owners single out the mesh cups for not getting hot. One owner calls it more comfortable for long sessions than the G Pro X, and a 2024 thread describes it as very comfortable with good mic and audio.

Fit is where it divides. The suspension band is notchless with two peg positions and limited extension. Tom’s Guide’s reviewer found the pegs either too tight or too loose, needed to adjust each earcup separately, and could not get a reliable seal. PCWorld judged the all-plastic headband a bit flimsy, and Tom’s Guide said the whole headset felt that way. The earcups do not swivel or fold, so the headset is bulky and will not pack flat. The USB-A dongle is bulky too: over an inch long and nearly half an inch thick, it can block an adjacent wired-mouse port on a laptop.

Isolation is the one weakness both labs agree on. SoundGuys scored attenuation 3.2 out of 10 and blamed thin fabric pads over modest pad thickness. RTINGS lists poor passive noise isolation as a con, describes the headset as blocking out very little ambient sound, and notes it leaks less at high volume than the G535. There is no ANC. Fine in a quiet room, poor in a shared one.

G HUB, range and repairs

DTS Headphone:X 2.0, LIGHTSYNC RGB, EQ, Bass Boost and the remappable mute button all live in G HUB, and none of it works on PS4. Android Central also found PS5 loses DTS:X. IGN’s test is the warning sign: on one of two PCs the EQ, Surround Sound, Assignments and G-Shift panes were missing entirely, a full reinstall did not fix it, and the second machine worked fine. Owners in the same r/logitech thread that documents the headband problem report G HUB connection failures too.

Range claims disagree. Product pages and retailer spec sheets say 20 m; Logitech’s support spec page says 15 m in 360 degrees. In practice IGN had usable audio out to nearly 100 ft and PCWorld saw no drop walking from desk to kitchen, while Tom’s Hardware lost the connection in one bedroom. Judge it by your floorplan, not by the number on the box.

Repairs are middling. Logitech’s support page states the battery is not user replaceable, yet iFixit publishes a battery replacement guide: remove the right earpad, undo four screws, and do not puncture the cell. The same wiki documents a 5 to 10 second reset via the button under the left earcup for connection and battery-registration problems, which is the first thing to try. Logitech lists no spare parts and sells neither replacement earpads nor spare dongles, so a lost receiver means contacting Logitech support. Third-party pads, microphones and headbands are the only route, and owners put replacement headbands at about $10. An iFixit forum thread from March 2025 describes an earcup that broke off and stayed attached by a wire; another from January 2024 covers random static. The 2-year warranty comes from retailer listings for part 981-000863, since Logitech’s own US pages do not state a term.

Is it worth it?

Logitech’s own US store listed the black headset at $119.99 in October 2026, with free shipping, 30-day free returns and a 20% discount when bundled with another Logitech peripheral. The launch price was $129.99, which is roughly where most instrumented testing was done.

Above about $140 the case thins. PCWorld reviewed it at $139.99, and SoundGuys named the Razer Barracuda X (2022) and SteelSeries Arctis 1 Wireless at roughly $99, with the Corsair HS70 Pro as IGN’s sub-$100 alternative. SoundGuys’ own verdict is that if you will not need to block anything louder than idle chatter, the G733 is pretty much a slam dunk, and that condition stops holding as the price climbs.

Buy it for weight, comfort and lights-off battery life. Accept poor isolation, a short mic that will not stay put, no Bluetooth, no wired fallback and a software dependency. Running cost is zero: no consumables, and Logitech sells neither pads nor spare dongles.

Which model this is

This page covers the Logitech G733 LIGHTSPEED Wireless RGB Gaming Headset, regulatory model A00178, released 2020-08-25, in four colorways: part 981-000863 black, 981-000882 white, 981-000889 lilac and 981-000942 blue. SoundGuys tested 981-000889, the lilac unit.

Do not confuse it with the G933, G935, G522 LIGHTSPEED or G Pro X. Logitech’s own G522 comparison page documents different drivers, sample rate, battery, range, RGB zones and weight for the G522, and RTINGS treats the G522, G535 and G735 as separate tested models. The Amazon listing for the black variant is ASIN B08141GQQG.
