Logitech G635 Review

Our Verdict
Our Analysis and Test Results
Comfort
The G635 only received so-so marks; none of our judges could wear this headset for a full day, and most of them found 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.
Audio
The G635 did quite a bit better in our audio tests. We could understand what other players were saying quite easily, 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 quiet and hollow, similar to speaking in a large empty room. The ear cups on this headset have a closed 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. 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.
Microphone
When wearing the G635, our voices came across quite clearly 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
The G635 has a companion software program that you can use to adjust the equalizer, programmable buttons, or lights, but it 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.
Value
The G635 isn't a great value, pairing a relatively lackluster performance with a slightly higher than average price tag.
Conclusion
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.
