Logitech G435 LIGHTSPEED Wireless Headphones Review

The Logitech G435 have a somewhat nondescript look. They have coiled audio cables that lead from the ear cups up into the headband, which gives them a slightly more gamer-centric design. In the 'Black & Neon Yellow' variant, they don't stand out from the crowd. However, if you're looking to make a statement, they come in two more eye-catching color variants: 'Blue & Raspberry' and 'Off-White & Lilac'.

The Logitech G435 have a comfortable fit. They're extremely lightweight and have a good clamping force, so you can wear them for long periods without feeling too much fatigue. They also have memory foam ear padding, which feels nice on the skin. However, they have a limited range of motion, and since they're designed for teens, they may not fit on extra-large heads.

The Logitech G435 have sub-par controls. There aren't a lot of buttons but there are a lot of controls, which aren't intuitive out of the box. These headphones don't come with a manual either, though Logitech provides a digital copy here. There are beeps for a lot of the commands like reaching max volume as well as a crescendo beep when you unmute the mic and a decrescendo beep when the mic is muted. The buttons are also pretty clicky. However, there's no feedback to let you know when you've reached the min volume.

On/Off button:

• One press: Indicates battery level. When the light is green, you have roughly 31-100% of battery life. When red for five seconds, there's 15-30% of battery life remaining. Finally, if the light is flashing red, you have under 15% battery life left.
• Hold for 1.5 seconds: Turns the headphones on.
• Hold for 3.0 seconds: Turns the headphones off.

Volume button: Raises and lowers the volume.

Mute Mic button:

• Short press: Mutes and unmutes the mic.
• Hold for 5.0 seconds: Switches the connection. When the light is cyan, you're using non-Bluetooth wireless. When the light is blue, you're using Bluetooth.
• Double press: activates mic sidetone, which allows you to hear feedback of your own voice.
• Single press (while holding the 'volume up' button): Raises sidetone.
• Single press (while holding the 'volume down' button): Lowers sidetone.
• Hold for 3.0 seconds (while holding the 'volume up' button): Sets the volume limiter to 100 dB.
• Hold for 3.0 seconds (while holding the 'volume down' button): Sets the volume limiter to 85 dB.

These headphones aren't really portable, which is to be expected for gaming headphones. While they're a bit smaller in size than other Logitech products like the Logitech G733 LIGHTSPEED Wireless, they don't fold or swivel inwards to help reduce their footprint. They also don't come with a carrying case to help protect them when you're on the move.

The Logitech G435 have an alright build quality. They're mostly made of lightweight plastic. The headband is covered in fabric, while the ear cups have cloth-covered memory foam padding, which is a nice touch. However, they don't feel the most sturdy, especially as the headband's cloth covering could rip with time. The hinges may also wear down over continuous use.

The Logitech G435 are reasonably stable. If you're gaming from your couch or desk, they shouldn't move around too much. However, they're not designed for use during physical activity, and they can fall off your head with larger or more vigorous head movements.

The Logitech G435 have a slightly warm sound profile that delivers a touch of extra boom to your mixes, which can help bring out sound effects. Vocals and lead instruments are present but a bit bright. However, they lack an EQ to help you customize their sound to your liking.

Note: These headphones have a volume limiter that you can set to either 85dB or 100dB. When set to 85dB, we could reach a max volume of 91dB, which isn't ideal if you want to protect the hearing of younger listeners. That said, we conducted all of our sound tests with the volume limiter off.

The Logitech G435 have mediocre frequency response consistency. Their audio delivery is dependant on their fit, seal, and positioning on your head, and they're prone to inconsistencies in bass and treble delivery. You may notice a drop in bass if you have thick hair or wear glasses.

The bass accuracy of the Logitech G435 is good. They lack a bit of a thumpy low-bass, but the rest of the range is overemphasized, so mixes have a bit of extra body and boom.

Note: The response here represents the average bass response, and as bass delivery can vary across users, your experience may vary.

The mid accuracy is excellent. There's a bit of overemphasis coming from the bass range into the low-mid, which can slightly clutter mixes. A dip in the mid-mid also nudges vocals and lead instruments to the back of the mix. However, the high-mid is very flat and neutral, so these sounds are clear and detailed.

The Logitech G435 have decent treble accuracy. There's a small peak in the low-treble that keeps vocals and lead instruments present and detailed. However, a dip in the mid-treble dulls sibilants like cymbals.

Note: The response here represents the average treble response, and as treble delivery can vary across users, your experience may vary.

The Logitech G435's peaks and dips performance is decent. There's a wide peak between the low-bass to low-mid, which adds thump, body, and boom to mixes. A dip in the low-mid pushes vocals and lead instruments to the back of your mix, while a large peak in the low-treble makes the upper harmonics of these sounds harsh. An uneven mid-treble range turns sibilants like S and T sounds alternatingly dull and painful.

The Logitech G435 have great imaging. The group delay falls below the audibility threshold, resulting in tight bass and transparent treble reproduction. The L/R drivers are also well-matched in amplitude and frequency response, which ensures a balanced stereo image. However, there's a very large peak in the phase response's mid to treble range, affecting the accurate placement of objects like voices in the stereo image. It seems to be louder from the left driver and is somewhat off-centered. It's also audible with regular content. However, our results are only valid for our unit, and yours may perform differently.

The Logitech G435 have a passable passive soundstage. The soundstage seems large, natural, and somewhat open. However, sound is perceived as coming from inside your head rather than from speakers placed in the room around you.

These headphones are compatible with Dolby Atmos. However, you need a license for this, which isn't included in the box. They're also compatible with PS5's Tempest 3D AudioTech as well as Window Sonic Spatial Audio.

The Logitech G435 have a very good weighted harmonic distortion performance. There's a small peak at normal volumes in the low to mid-treble, but this can be hard to hear with real-life content. As a result, the rest of the frequency range falls within acceptable limits, resulting in clean and pure audio reproduction.

These are the settings used to test the Logitech G435 LIGHTSPEED. Our results are only valid when used in this configuration.

The Logitech G435 have poor noise isolation. They don't block out any bass-range noise like the low rumble of bus and plane engines. They also really struggle to cut down ambient chatter, although they do a better job of reducing the high-pitched hum and an AC unit.

The Logitech G435 have a sub-par leakage performance. Leakage is concentrated between the mid to treble range and sounds somewhat full-bodied. If you like to listen to your audio at high volumes, others around you can hear it, even if you're in a moderately noisy environment.

The recording quality of the Logitech G435 is fair. Your voice sounds bright but a bit unnatural and lacking in body. However, speech is still clear.

The microphone's noise handling performance is mediocre. The mic struggles to separate your voice from moderate ambient noise. If you're talking near an open window with a lot of traffic outside, your voice may be drowned out by ambient sound.

The Logitech G435 have a very good battery performance. They're advertised to last 18 hours continuously, and we measured just under 20 hours. However, battery life can vary depending on usage, and your real-life experience may be different. They have an auto-off timer that activates after 30 minutes of inactivity to help conserve battery life when you're not using them. Unfortunately, they don't have an AUX port, and you can't use them passively. You also can't use them while they're charging.

These headphones have decent Bluetooth connectivity. They have low latency on PCs as well as Android and iOS devices, which is good for wireless gaming. However, while they support Bluetooth, you can't connect to both a Bluetooth device and a console at the same time.

Note: We couldn't determine the Bluetooth version as it isn't mentioned on the manufacturer's website, in the manual, or on the box.

The Logitech G435 have satisfactory non-Bluetooth wireless connectivity. Using their USB dongle, their latency is a bit high, which can cause your audio and visuals to fall out of sync. If you're looking for wireless Logitech headphones with lower latency, check out the Logitech G535 LIGHTSPEED Wireless.

These headphones only come with a USB-A to USB-C cable for charging up the headphones. This cable doesn't support audio, though.

These headphones are fully compatible with Bluetooth-enabled PCs. You can also use them with full audio and mic compatibility via their wireless dongle.

You can only use the Logitech G435 LIGHTSPEED on PS4 and PS5 consoles via their wireless dongle. However, you have full audio and mic compatibility.

These headphones come with a wireless USB-A dongle that works on PlayStation consoles as well as PCs. It delivers full audio and mic compatibility.
