Logitech G733 LIGHTSPEED Wireless Headphones Review

The Logitech G733 look a lot like the Logitech G535 LIGHTSPEED Wireless with a reversible inner headband as well as textured ear cup lining. What makes them stand out a little more from the crowd is the RGB lighting strips on their ear cups that can be customized in their companion software, unlike the wired Logitech G335. They can be purchased in black, white, or more eye-catching hues, like pale purple and bright blue.

These headphones are quite comfortable. They're relatively lightweight, have a supportive headband, and don't clamp your head too tightly. Unfortunately, they're a little big and don't offer much in the way adjustability, with the headband only having two adjustment notches and the cups not being able to rotate. If you're looking for Logitech headphones with a smaller fit, consider the Logitech G435 LIGHTSPEED Wireless instead.

The Logitech G733 have an easy-to-use but somewhat limited control scheme. There's a dedicated on/off button, an infinite scroll wheel for volume adjustment, and a mic muting button whose function can be remapped in the headphones' companion app. While the volume scroll wheel doesn't have a physical notch and is quite easy to accidentally adjust, it beeps to let you know when you've reached max volume. There are also audio cues for when you've muted and unmuted the mic, which is good since the buttons themselves don't offer much tactile feedback.

The Logitech G733 aren't very portable, which is normal for dedicated gaming headphones. While they don't weigh that much, they're very bulky and don't fold or have rotating ear cups to reduce their overall footprint. It should also be noted that you'll need to bring their wireless USB dongle everywhere you go in order for them to function.

The Logitech G733 don't come with a case or pouch.

The Logitech G733 are decently well-built. They're mostly made of plastic but feature a cloth headband and fabric-lined memory foam padding on the ear cups. The detachable microphone is also malleable. Overall, they feel like they should survive some drops and bumps and have few obvious weak points, aside from the middle of the plastic headband and the ear cup yokes.

The Logitech G733 are reasonably stable. They shouldn't have any issues staying on your head if you intend to use them for gaming while sitting down, but they move around with moderately intense head movements and are likely to fall completely off during high-intensity workouts. However, their wireless design eliminates the chance of an audio cable snagging on something and pulling them from your head.

These gaming headphones have a reasonably well-balanced sound profile. They should be well-suited to listening to a wide variety of audio content. That said, those who prefer a little more thump and rumble in their games or music might be slightly disappointed with their slightly underemphasized default bass response. Thankfully, their out-of-the-box sound profile can be modified via audio presets or a graphic EQ in the Logitech G HUB companion software.

The Logitech G733's frequency response consistency is poor. Their audio delivery is heavily dependent on fit and positioning, especially in the bass and treble region. If you have long hair that covers your ears or wear glasses, achieving a consistent listening experience can be difficult.

The Logitech G733's bass accuracy is great. While the underemphasis in the low through mid-bass can lessen overall thump and rumble, the range is still quite well-balanced overall. That said, your listening experience may vary, as their audio delivery is heavily dependent on their fit and positioning.

These gaming headphones deliver great mid accuracy. Vocals, lead instruments, and dialogue should sound clear and full-bodied, though dips in the mid and high-mid range can nudge these notes toward the back of the mix and slightly weaken them.

The Logitech G733's treble accuracy is decent. The low through mid-treble range is underemphasized, resulting in a slight loss of detail for vocals and lead instruments and slightly dull and lispy sibilants.

The Logitech G733 have good peaks and dips performance is good. There's a bump across the high-bass through low-mid range that muddies vocals and lead instruments. There's also dips in the mid-mid and high-mid ranges that push those same frequencies toward the back of the mix and weaken them. An extended bump through the low-treble range makes some notes sound harsh while the steep peak in the mid-treble makes some sibilants piercing.

These gaming headphones offer excellent stereo imaging performance. Their weighted group delay falls entirely beneath the audibility threshold, resulting in tight bass and transparent treble. The L/R drivers are well-matched in regards to amplitude, frequency, and phase response, meaning that these headphones can accurately place objects like voices and footsteps in the stereo image. Note that these results are only valid for our test unit, and yours may perform differently.

The Logitech G733 provide a mediocre passive soundstage. Due to their closed-back enclosure, they don't provide as spacious a listening experience as open-back headphones. Sounds mostly seem to be perceived as coming from the inside of your head, rather than speakers placed around you.

These headphones feature the DTS Headphone:X 2.0 virtual surround sound feature. However, you'll need to activate it in the headphones' companion software, and we don't currently test this feature's performance.

The Logitech G733 have good weighted harmonic distortion performance. Aside from peaks in the mid and high-treble ranges, the rest of the frequency spectrum falls within acceptable limits, resulting in clean and pure audio reproduction.

These are the settings used to test the Logitech G733. Our results are only valid when they're used in this configuration.

These over-ears have poor noise isolation. They don't filter out any ambient noise in the bass range or most of the mid-range, meaning that you'll hear everything from the low-rumble of a bus engine to the chatter of your coworkers. Thankfully, they do a good job of blocking out high-pitched noises, so you shouldn't hear things similar to the hum of a nearby AC unit.

The Logitech G733 have a decent audio leakage performance. Most of the escaping audio occurs in the mid-range, making it sound somewhat full-bodied. If you blast your music in a quiet office, your coworkers can probably hear what you're listening to.

These headphones have a detachable boom microphone.

The boom microphone has fair recording quality. While your voice should sound clear, natural, and mostly free of distortion, the microphone frequency response shows a severe underemphasis in the bass range. This means that your voice may sound very thin and lacking in body.

The boom microphone does a remarkable job of isolating speech from loud ambient noise, in no small part due to its noise gate processor. People on the other end of the line shouldn't have too much trouble understanding you, even if you're calling from an especially loud or crowded environment.

Note: The noise gate processor's sensitivity can be adjusted in the headphones' companion software, but it can't be deactivated, meaning that it had an impact on the score given. That said, the mic would have still likely scored well in this respect even in the absence of a noise gate.

The Logitech G733 have an impressive battery performance. They provide more than 21 hours of continuous playback time and feature an auto-off timer, which can be adjusted in their companion software. Unfortunately, you can expect it to take close to 4.5 hours to fully recharge them, but at least, you can still use them while they're charging.

These gaming headphones are compatible with the Logitech G HUB software. It grants you access to a huge variety of configuration options, including a graphic EQ, audio presets, button remapping, auto-off timer adjustment, and a customization menu for their RGB lighting strips. The BLUE VO!CE feature allows you to customize your microphone settings in-depth. Unfortunately, there have been quite a few user reports of various problems when using the Logitech G HUB software. This includes but isn't limited to startup issues, freezing, and connection issues with some devices. Even though we didn't encounter any issues with this software, if you've experienced problems with it and your unit, please leave us a comment in the discussions.

The Logitech G733 are not Bluetooth-compatible and instead rely on their proprietary wireless USB dongle.

These over-ears have okay non-Bluetooth connectivity. Their proprietary wireless USB dongle has higher latency than the Logitech G PRO X WIRELESS LIGHTSPEED Gaming Headset and can cause your audio and visuals to be slightly out of sync. If you're looking for Logitech headphones with a better latency performance, consider the Logitech G735 Wireless, which have very low audio lag.

These headphones are wireless-only. They come with a USB-C to USB-A cable for charging or connecting to your PC to configure them.

These headphones aren't compatible with Xbox One consoles.

The Logitech G733 don't have a dock, but they do come with a wireless USB dongle that grants full audio and microphone compatibility with PC and PS4 systems.
