Our Verdict

Finishing almost exactly in the middle of the group overall, the Logitech G635 failed to merit any awards or other commendations. Our testers and judges didn't find this headset to be all that comfortable but it does have decent sound and microphone quality. It also is packed with extra features and functions, making it one of the easier to use headsets. However, it also is quite pricey and was thoroughly outperformed by other models that cost less than half as much in our tests, making it hard for us to recommend.

Our Analysis and Test Results

The G635 finished just behind the beyerdynamic MMX 300 and ahead of the Cloud Revolver S. The Cloud Revolver S and the G635 both scored about the same, with the Revolver's superior comfort averaging out the better sound and mic quality of the G635. These headsets also retail for about the same price, which is a little less than half that of the beyerdynamic. The MMX 300 does have the best audio and mic quality of these three headsets, but we didn't find it to be particularly easy to use or all that comfortable, which is a shame, given its premium price and superb sound quality.

Performance Comparison

To determine which gaming headset is truly the greatest of them all, we did tons of analysis and research on dozens of different headsets, then bought the most promising models to test out head-to-head. We graded each headset's performance in four different weighted rating metrics, with the G635's results discussed below.

Accountable for 40% of the overall score for each headset, comfort is the most significant component of our tests. To evaluate each headset, we had a wide variety of different users try out each headset for a lengthy period of time, then averaged the results. In particular, we were looking for how long they could comfortably wear them, how the headband and ear cups fit, and if there were any uncomfortable pressure points, even when wearing glasses. The G635 only received so-so marks, earning it a 5 out of 10.

None of our judges could wear this headset for a full day, with most of them finding it to be quite uncomfortable after 4-5 hours. The headband is covered with microfiber mesh and the fit is a bit on the tighter side, so this headset is usually a better fit for gamers with smaller heads. Our judges found that this fit created a non-trivial amount of pressure and discomfort after a while, hurting the G635's score quite a bit.

The ear cup padding is on the firmer side and is also covered in microfiber mesh. However, the ear cups are quite large — in direct contrast to the tight headband fit — measuring about 3" tall and 1.875" across.

After our comfort evaluations, we moved on to rating the sound quality of each headset, which accounts for 30% of the final score. In addition to grading and scoring how each headset replayed other players' voice, we also listened to different types of music and other in-game sounds and rated the playback. Additionally, we also subjected each product to a set of audio benchmarking tests and looked at how well they block out ambient noise. The G635 did quite a bit better, earning a 7 out of 10.

We could understand what other players were saying quite easily with the G635, although their voices didn't sound quite as rich and full as they would if you were talking in person. The reproduction by the G635 seems a little on the quiet and hollow side, similar to if you were talking in a large empty room. The ear cups on this headset have a close back, so they also do a fairly good job at cutting down external noise in whatever room you are playing in, reducing sounds by about 20% or so in our experience.

When it came to identifying the origin of a sound within a game, the G635 did an absolutely excellent job — almost perfect in fact. Regardless of whether the sound was another player's footsteps, gunfire, or an explosion, we could always tell where it was coming from.

For our trio of audio benchmarking evaluations, the G635 did very well in two of them. It did a fantastic job with the binaural recording and the drivers are very well matched, but we did get a slight amount of parasitic buzz in the bass quality test. This carried over into our music assessment, with the bass being a bit on the weak side compared to the mid and treble tones.

Responsible for 20% of the total score, mic quality was next on the testing docket. For this test, we had our judges rate how well the G635 picked up and transmitted voice and how recordings of our voices sounded, as well as how well it did at filtering out background noise or side conversations. The G635 again did very well, meriting a 7 out of 10 for its performance.

Our voice came across quite clear in recordings and to other players, sounding very full and having little to no feedback at most mic levels. However, we did notice that feedback can become quite prominent at higher mic levels. We did especially appreciate that the G635 isn't overly sibilant and doesn't overexaggerate hard "t" sounds.

This headset does a good job of filtering out ambient white noise and doesn't make too loud of a sound for the other person when you mute or unmute the mic but it will almost always pick up a side conversation happening in the same room.

Ease of Use

Our final metric for gaming headsets focused on the different convenience factors each one has, which is responsible for the remaining 10% of the total score. The performance of the G635 again was very good, earning it a final 7 out of 10.

The G635 does have a companion software program that you can use to adjust the equalizer, programmable buttons, or lights but is otherwise ready to go out of the box. It has onboard controls right on the headset that allow you to adjust the volume and mute the microphone. Additionally, you can also mute the mic by lifting it out of the way.

The cord is about average in length and is detachable, so you can easily replace it if it gets damaged or remove it for storage or transport. However, the mic is not detachable.


The G635 isn't a great value, pairing a relatively lackluster performance with a slightly higher than average price tag.


Overall, the G635 did fine. It's definitely not our favorite headset but we wouldn't strongly dissuade you from purchasing. It's just a bit pricey relative to its performance and there are far better headsets out there that cost about the same or even less.
