Logitech G733: problems, parts and running costs

Checked: 2026-10-06

Summary

The G733 is a 278 g all-plastic wireless headset from 2020, and its weak points are narrow and well documented: battery that some owners measure far below the claim, suspension headband and earcup plastic breaking, and every extra feature living inside G HUB. Logitech sells no consumables, no replacement earpads and no spare receivers, so the yearly running cost is electricity only. It is a sensible buy at or below about $130 for someone in a quiet room who wants a very light headset with fabric pads and long lights-off battery life; above about $140 the roughly $99 headsets are the better purchase.

Common problems and fixes

Battery drains faster than advertised — the 29 h figure only applies with lighting off at 50% volume, and the lighting is where the budget goes: Android Central put the loss to RGB at roughly 9 h. Owner threads on r/LogitechG describe a headset that never held a charge longer than 3 h and never gave a low-battery warning before shutting down, against other owners measuring about 20 h with lighting on and closer to 30 h with it off, and one measuring a little under 10% an hour after a year of daily use. The community advice is to charge it overnight, run it flat once, then ignore the percentage reading. Switching off LIGHTSYNC is the only saving that matters. No first-party warranty term is published; a 2-year term appears on retailer listings for 981-000863 and 981-000886. [11][12][16][17][18][19]
G HUB freezes on “charging” or shows the wrong percentage — one owner reports the battery level in G HUB stuck while displaying charging, another a replacement pair that would not charge past 7%, and another a percentage that stayed wrong through both a device reset and a full G HUB reinstall. Before assuming a dead cell, hold the reset button under the left earcup for 5 to 10 seconds, which is the first step in iFixit’s troubleshooting wiki for both connection and battery-registration problems, then charge to completion and re-read the level in G HUB. [13][14][7]
Suspension headband loses its spring, earcup plastic cracks — iFixit’s Q&A page carries a request for replacement headband pieces, a repair-forum thread from 2025-03-24 describes an earcup that broke off and stayed attached by a wire, and an r/logitech thread describes the headband suspension losing its spring, with replacement headbands quoted at about $10. Logitech lists no spare parts, so third-party headbands, earpads and microphones are the only route, and the 2-year retailer-stated warranty is the only cover if the break falls inside its term. [9][10][15][18]
EQ, surround, assignments and G-Shift panes missing in G HUB — IGN lost all four panes on one of two test PCs, and a full reinstall did not bring them back, while the second machine worked normally. DTS Headphone:X 2.0, LIGHTSYNC RGB, EQ, Bass Boost and the remappable mute button all live in G HUB, and none of them work on PS4, so without working software this is a plain 2.4 GHz headset. Owners report G HUB connection failures in the same thread as the headband problem. Install G HUB and confirm the panes load before the return window closes. [3][15][17]
The 6 mm boom mic is too short and will not hold position — the detachable boom is a short stick with no telescoping arm, so it does not reach a normal mouth position and slides out of place; Tom’s Hardware’s teammates also heard it as muddy or nasal with the Blue VO!CE defaults on. Blue VO!CE is the real fix, since SoundGuys found it improves the raw mic noticeably and it adds presets, EQ, compression, gating and filtering. There is no mute indicator light on the boom, and the fit problem is a design limit that no warranty term covers. [6][5][4][1]
Random static or crackling — an iFixit repair-forum thread from 2024-01-19 reports static appearing at random. The iFixit troubleshooting wiki lists codec mismatch and a low battery among the causes and prescribes the 5 to 10 second reset under the left earcup first. Charge fully, then test on the same PC and the same USB port before treating it as a hardware fault. [10][7]
Almost no passive noise isolation — SoundGuys measured attenuation at 3.2 out of 10 and blamed thin fabric pads over modest pad thickness, and RTINGS lists poor passive isolation as a con and describes the headset as blocking out very little ambient sound. There is no ANC and no software fix. Thicker third-party pads are the only lever, and swapping pads changes the seal, which changes the sound. This is a known compromise rather than a fault. [1][2]
Fit varies and the headset will not pack flat — 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, adjusted each earcup separately and could not get a reliable seal, and both Tom’s Guide and PCWorld judged the all-plastic frame flimsy. The earcups neither swivel nor fold, so the headset is bulky in a bag, and the USB-A receiver is over an inch long and nearly half an inch thick, which can block an adjacent wired-mouse port on a laptop. Sound also shifts between wears because delivery depends on the seal. [5][6][2][3]

Parts and consumables

Earpads (no part number published) — the pads pull off, but Logitech sells no replacements and its support page lists no spare parts, so third-party pads are the only option. No verified price, store or month-year exists for a compatible pad. [1][17]
Detachable boom microphone (6 mm, no part number published) — it detaches from the headset and third-party replacement microphones are sold for this model, which is why it shows up in repair threads. No verified price, store or month-year exists. [17][1]
Suspension headband (no part number published) — owners put third-party replacement headbands at about $10. Logitech’s product page sells headband straps and mic covers separately as accessories, but no headset headband spare. [15][17]
Battery (1500 mAh / 5.55 Wh lithium polymer) — Logitech’s support page states it is not user replaceable. iFixit publishes a step-by-step guide anyway: remove the right earpad, undo four screws, and do not puncture the cell. SoundGuys calls it not practically replaceable in the field. [17][8][1]
LIGHTSPEED USB-A receiver — a single point of failure with no replacement route: Logitech sells no spare dongles, so a lost receiver means contacting Logitech support. [1][17]
In the box — headset with the reversible soft headband attached, detachable microphone, LIGHTSPEED USB-A receiver and a USB-C to USB-A charging cable. No wall adapter is listed. [17]

Yearly running cost

Nothing to buy from Logitech: no consumables, no proprietary pads, no dongle replacement and no subscription, so the running cost is electricity. The cell holds 5.55 Wh, so each full charge draws 5.55 Wh before charging losses. At the 20 h with-lighting figure that is roughly 18 full charges a year, and at the 29 h lights-off figure roughly 13, both a little over 100 Wh a year. Multiply by your own utility rate per kWh to get the figure; against a purchase price in the low hundreds it is negligible. The only spending most owners ever do is third-party pads or a replacement headband after a break, and no verified price for either was found. [1][17]

When it is a good buy

Logitech’s own US store listed the black 981-000863 at $119.99 in October 2026, with free shipping, 30-day free returns and a 20% bundle discount when bought with another Logitech peripheral. The launch price was $129.99, which is roughly where most instrumented testing was done. Thresholds: at or below about $130 it makes sense if you want a very light headset, fabric pads that do not get hot, and lights-off battery life that measures true. Above about $140 the case thins, since PCWorld reviewed it at $139.99 while SoundGuys’ roughly $99 alternatives undercut it on build quality and mic mounting; IGN’s sub-$100 alternative was the Corsair HS70 Pro. [17][1][6][3]

Razer Barracuda X (2022) — roughly $99 at SoundGuys’ review time. The better choice when you want a stiffer frame and a mic that holds its position instead of sliding out.
SteelSeries Arctis 1 Wireless — roughly $99 at the same review time. The better choice when you are buying on price and do not need RGB or the fabric suspension band.
Logitech G735 — $208 at SoundGuys’ review time. The better choice when you want a metal frame, Bluetooth and a proper boom mic, and you are willing to pay a much larger sum for them. [1]
