Logitech G333 Headphones Review

The Logitech G333 are sleek-looking wired in-ear headphones with brightly-colored silicone tips. They come in a few different color schemes. We purchased the black G333 model with blue tips, but you can also buy them in white/violet and purple/yellow. There's also a League of Legends K/DA variant, which have a white and blue color scheme.

These are comfortable headphones. They're lightweight and don't put pressure on your ears when you wear them. However, you may feel some suction when you take them out of your ears.

The Logitech G333 have okay in-line controls. There are buttons for raising and lowering the volume, and the center button lets you play/pause audio content or answer/end phone calls. If you're using the headphones with a mobile device, you can also press and hold the center button to activate the voice assistant. The buttons are very clicky and give better feedback than the Turtle Beach Battle Buds' controls, but unlike those headphones, you can't mute the microphone or skip tracks using their in-line controls. There also aren't any audio cues.

Like most in-ears, the Logitech G333 are incredibly breathable. They shouldn't make your ears feel warm during long gaming sessions or even during intense workouts, although they aren't really designed for use during physical activity.

These are fantastically portable headphones. The earbuds are very compact and should easily fit in most bags and pockets.

The Logitech G333 come with a sub-par case. It's a basic pouch made of a cloth material that isn't waterproof. It has thick padding and opens with a zipper, so it's easier to get the headphones into it compared to drawstring pouches like the one that comes with the Turtle Beach Battle Buds.

The Logitech G333 have a good build quality. The earbuds are lightweight and have a metal finish with a good flat silicone cable. The tips and cable feel like they could rip after a while, though. These headphones don't have an IP rating for dust and water resistance, which is common for gaming headphones.

The Logitech G333 are decently stable headphones once you achieve a good fit with the silicone tips. The cable can easily get hooked on something and yank them out of your ears, but if you can avoid that, they should stay in your ears with no problem when you're gaming.

The Logitech G333 have a bass-heavy, boomy sound profile. Mixes have lots of body and punch, which helps emphasize sound effects in video games, but some may find they sound muddy and cluttered. Unfortunately, they lack any sound customization features, so you can't adjust their sound profile to suit you.

The Logitech G333 have incredible frequency response consistency, like most in-ears. Once you achieve a good fit, you should experience consistent audio delivery each time you wear them.

These headphones have poor bass accuracy. The bass range is overemphasized, especially the mid-bass and high-bass ranges, so your mixes have extra thump, rumble, and punch, but some may find they sound boomy and muddy.

The Logitech G333 have good mid accuracy. The low-mids are overemphasized, which makes mixes sound cluttered and muddy. There's also a smaller dip in the high-mids, which slightly weakens lead instruments and vocals.

These headphones have good treble accuracy. The whole range is fairly even but underemphasized, so instruments and vocals lack detail and presence, and sibilants like S and T sounds are dull.

These headphones have excellent peaks and dips performance. There's a peak in the high-bass that adds warmth and boom to your audio, while a dip in the mid-mids nudges vocals and lead instruments towards the back of the mix. The mid-treble is uneven, so sibilants like cymbals can be piercing or dull, depending on the frequency.

These headphones have a fantastic stereo imaging performance. Their weighted group delay falls below the audibility threshold for the entire range, resulting in tight bass and transparent treble reproduction. The L/R drivers are well-matched in amplitude, frequency, and phase response, so objects like footsteps are accurately placed within the stereo image. However, that these results are only valid for our unit, and your experience may vary.

The Logitech G333 have an awful passive soundstage, like most in-ears. Because they don't interact with your outer ear, their sound seems to be coming from inside your head instead of from speakers in the room around you. Also, because of their closed-back design, the soundstage doesn't seem as spacious as open-back headphones.

The Logitech G333 have a good weighted distortion performance. There's a small amount of distortion in the mid-treble range at normal volumes, but it may not be audible to most listeners. Aside from that, most frequencies fall within good limits, resulting in fairly clean and pure audio reproduction.

These are the settings we used to test these headphones. Our results are only valid when using these settings.

The Logitech G333 have mediocre noise isolation. They do an okay job of blocking out sounds like background conversations or the high-pitched hum of an A/C unit. They don't really reduce noises like the rumble of a bus or plane engine, however.

The Logitech G333 have an amazing leakage performance. You should be able to listen to your music at high volumes in a moderately quiet environment like an office without bothering people around you too much.

The mic has a decent recording quality. Your voice sounds a bit thin and muffled, but it's still easy to understand. If you're looking for wired earbuds with a mic that has an even better recording quality, consider the SteelSeries TUSQ.

Update 10/18/2021: These headphones have been updated to test bench 1.5. In this update, we made changes to the way we test noise handling. We now use a subjective evaluation of our audio clips. This new method has resulted in different results than what we had reported in our previous test bench. As a result, the scoring of this box has changed, and we have updated our results.

The microphone has sub-par noise handling. If you use these headphones to talk on the phone in a noisy environment like a subway station, the person on the other end may not be able to hear you clearly.

Update 10/18/2021: These headphones were updated to Test Bench 1.5 and we've retested their USB-C audio latency on PC and Android. When using the adapter on PCs, we measured 109 ms of latency and 11 ms of latency on Android devices. As a result, we have updated our text to better reflect these measurements.

These headphones use a 1/8" TRRS connection and come with an analog to USB-C adapter, so you can use them with phones or PCs that don't have an audio jack. They have high latency when connected to PCs via their USB-C adapter, which is disappointing if you're gaming. However, their latency on Android devices when using the USB-C adapter is much less, so you shouldn't experience too much delay between your audio and visuals. Some apps and devices seem to compensate for latency differently, though, so your real-life experience may vary.

If you want to use these headphones with a VR headset, they come in another variant, the Logitech G333 VR gaming earphones. They lack mic support but come with a shorter cable that's less likely to get snagged on something while you're using the headset.

These headphones offer full audio and microphone support with Xbox One and Xbox Series X if you plug them into the controller.
