Logitech G733 LIGHTSPEED Wireless  Headphones Review

The Logitech G733 look a lot like the Logitech G535 LIGHTSPEED Wireless with a reversible inner headband and 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 you can customize in their companion software, unlike the wired Logitech G335. You can buy them in black, white, or more eye-catching hues, like pale purple and bright blue.

They have a comfortable fit. 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 of 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 mute button whose function you can remap 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 don't offer much tactile feedback.

They aren't very portable, which is normal for dedicated gaming headphones. They're bulky over-ear headphones and don't fold or have rotating ear cups to reduce their overall footprint. You'll need to bring their wireless USB dongle everywhere you go for them to function.

They have a decent build quality. 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'll survive some drops and bumps and have few obvious weak points, aside from the middle of the plastic headband and the ear cup yokes.

They have adequate stability. When gaming at your desk or on the couch, they won't fall off your head, even if you move your head a little. However, they can slip out of place if you move more exaggeratedly.

These gaming headphones have a reasonably well-balanced sound profile. They'll be well-suited to listening to a wide variety of audio content. If you like to hear the thump and rumble in game audio or music, you might be disappointed with their slightly underemphasized default bass response. You can modify their out-of-the-box sound profile 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 heavily depends on fit and positioning, especially in the bass and treble region. If you have long hair that covers your ears or wear glasses, it can break the ear cups' seal and cause a drop in bass. You need to adjust the headphones' fit and positioning on your head to get the same sound each time you use them.

Their bass accuracy is amazing. While the underemphasis in the low through mid-bass reduces thump, rumble, and punch, the range is still quite well-balanced overall. Your listening experience may vary, as their bass delivery depends more on the ear cups' seal against your head.

They have impressive mid accuracy. Vocals, lead instruments, and dialogue sound clear and full-bodied. These elements are slightly weakened by underemphasis in the mid and high-mid ranges, so in games with a lot of dialogue, like Fallout 4, voices seem less present and are pushed back in the mix, relative to boomy sound effects.

They have good treble accuracy. The whole range is underemphasized, which results in veiled instruments and vocals. Sibilants like S and T sounds are also dull.

They have a good peaks and dips performance, meaning the headphones control their sound profile well despite some deviations. A bump across the high-bass through low-mid range muddies vocals and lead instruments. There are also a few 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 higher-frequency sibilants piercing.

These gaming headphones offer excellent stereo imaging performance. Most Logitech headphones we've tested have very good imaging, indicating the brand's quality control and ergonomics. 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 amplitude, frequency, and phase response, meaning that these headphones can accurately place objects like voices and footsteps in the stereo image. However, imaging varies from unit to unit.

Their passive soundstage is mediocre. 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 from speakers placed around you, making for a less immersive listening experience.

These headphones feature the DTS Headphone:X 2.0 virtual surround sound feature, which is meant to make your audio seem more '3D' and provide a more immersive listening experience. You can activate the feature in the headphones' companion software.

They have a very 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 LIGHTSPEED Wireless Gaming Headset. Our results are only valid when you use the headset in this configuration.

These over-ears have poor noise isolation, which is normal for gaming headphones that don't have an ANC feature. They don't filter out ambient noise in the bass range or most of the mid-range, meaning you'll hear everything from traffic outside your window to people chatting in the next room. They can block out a decent amount of high-pitched noise, so they can help reduce the sound of a noisy computer fan or A/C unit.

The Logitech G733 LIGHTSPEED wireless have a decent leakage performance. Most of the escaping audio occurs in the mid-range, making it sound somewhat full-bodied. If you crank up the volume when you're gaming, other people in the room can hear it.

The boom microphone has fair recording quality. Recorded speech is clear and understandable but not particularly natural. It also sounds thin and tinny.

The boom microphone does a decent job of isolating speech from loud ambient noise, partly because of its noise gate. If there's noise from a busy street or conversations in the background in your gaming space, your voice is still easily understandable to whoever's on the other end of the line.

Note: You can adjust the noise gate processor's sensitivity in the headphones' companion software, but you can't deactivate it, meaning that it had an impact on the score given. That said, the mic would have still likely scored fairly well in this respect, even without a noise gate.

They have impressive battery performance. The manufacturer advertises a continuous battery life of 20 hours with the RGB lighting on, and we measured just over that. Logitech also advertises that you can get more battery, roughly 29 hours worth, with the RGB lighting off. The headphones are equipped with an auto-off timer to help save battery life, which you can adjust or turn off in the companion software. Unfortunately, you can expect the headphones to take 4.5 hours to fully recharge, but at least you can still use them while 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, several users have reported 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, please comment in the forums if you've experienced problems with it and your unit.

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, but you can't use it to receive audio.

These over-ears have excellent non-Bluetooth connectivity. They have similarly low latency to the Logitech G PRO X WIRELESS LIGHTSPEED Gaming Headset, ensuring your audio and visuals stay in sync while gaming.

They're fully compatible with PCs using the wireless USB dongle. However, they have somewhat high latency, which can cause your audio and video to fall out of sync. They can't connect any other way, like via Bluetooth or analog cable.

These headphones only have full mic and audio compatibility with PlayStation consoles using the USB dongle. However, they have somewhat high latency over non-Bluetooth wireless.

The Logitech G733 Wireless have a wireless USB dongle that grants full audio and microphone compatibility with PCs and PlayStation consoles.
