Features, sound, and conclusion
One of the most important features in a high-end headset, for me at least, is that 3.5mm analog jack. While there are doubtlessly many gamers out there who play exclusively on PC, personally I switch between PC and console on a daily basis. For me, leaving this feature off a headset at this price point is inexcusable, but it happens enough that Logitech's inclusion here is still laudable.
The biggest upgrade from the G933 though, is the switch from 40mm to 50mm drivers in each ear. Aside from obviously being 20% bigger, Logitech says it has redesigned the entire casing around the driver and claims the new driver cuts down on low-frequency distortion. We'll get into how it sounds down below, though.
Another big feature for the G935 is the addition of DTS Headphone:X 2.0. The first revision of Headphone:X made surround sound possible with two-driver headphones, but the 2.0 version allows game creators to put sounds anywhere, not just where surround sound speakers would generally be placed.
The advertised battery life is eight hours with the RGB LED lighting on and 12 hours with it off. This matches up well with my experience with the headphones. I went through about two full charges while testing these for gaming with the lighting on, and 16 hours total is about right.
How it sounds
When we're looking at a gaming headset rather than a pair of headphones, there are two distinct sound profiles (gaming and music) to consider, and two modes (wired and wireless).
On the gaming front, the DTS Headphone:X 2.0 really does make a difference. I played about eight hours of EA's Anthem demo and a few hours of my one true gaming love, Doom. Because Anthem was an all-new experience, it's a little harder to gauge the difference that the G935 made. In Doom, though, I was impressed with how well the surround sound works. I noticed noises I hadn't heard before, and it was helping me catch enemies at my back before they got me. The audio feels clean and clear, and the ability to adjust EQ through the G HUB software means that just about anyone should be able to find a sound profile that works for them.
Talking over Discord using the wireless connection, I was pleased with how clear my chat partners' speech came through, and they were especially impressed with how I sounded.
And that's because the results were a little less impressive when I plugged the headset in. In addition to my time gaming on PC, I spent a good chunk of time playing Sea of Thieves on Xbox One X, in multiplayer the whole time and with the headset plugged into the controller.
Game audio was acceptable. Here, the headphones simply act as 2.0 stereo cans, and they do a fine job of that. Where they fell short was in delivering my voice to my players. I have a couple friends I regularly play this game with. Normally when I play with them, I use Logitech's G Pro headset—a personal favorite because of its light feel, solid mic, and the excellent nylon-wrapped 3.5mm audio cable it comes with. The G935 has a shorter, rubberized cable that's acceptable but has all the problems that come with rubberized cables. It catches on things like zippers and has some (though not much) shape memory. It's not the worst, but I'm a little disappointed that the nylon cable didn't make the jump.
But back to the sound: My shipmates noticed right away that I was on a different headset than usual. "You sound weird, did you change headsets?" they asked. To troubleshoot a little bit, I switched to Logitech's also-new G432 and then to the G Pro. Both of those received high marks from my crew, but switching back to the G935 got the same lackluster result as before. I spent my time in Anthem with one of the same players. Thus, we had the same set of ears, using the same headphones, listening to me on three different headsets across two different gaming devices and networks, and the G935's Xbox performance stood out in a negative way. Given that the other two headsets sounded fine on the Xbox One X, it doesn't seem like Xbox Live is the problem. The same headset sounded better on the PC than on the Xbox, so it's not the headset mic itself. It seems like something about plugging in with the wired connection with this headset was the cause of the drop in audio quality. This is total conjecture, but my guess is that something bandwidth-related is getting in the way to make the audio quality drop.
As a set of music headphones, the G935 performs pretty well for a gaming headset, but personally, I still prefer my ATH-M50x headphones. It's worth keeping in mind, though, that they go for just $25 less and don't feature wireless technology, a microphone, a battery, LED lighting, or 7.1 surround sound. I'll admit some personal bias toward dedicated music headphones there. My M50x headphones get louder and sound clearer than the G935. By comparison, the G935 feels like offers less instrument separation, and in the default configuration it leans heavier on bass. Metallica's "Of Wolf and Man" didn't have the punch I expect from the drums, for example. Miles Davis' "Blue in Green" felt subdued.
I still found the sound acceptable, though, and I don't think the differences will stand out unless you're the kind of person who owns music headphones and has strong opinions about them.
The only big knocks I can offer against the G935 is the head pressure and console/wired sound quality. In every other department, it's a rockstar. It offers solid battery life and checks all those must-have boxes for a pricey gaming headset: 3.5mm connectivity (even if it's subpar), lift-to-mute mic, surround sound, and EQ functionality. DTS Headphone:X 2.0 feels like a substantial upgrade over Headphone:X, too.
If your primary gaming platform is a console or mobile phone, the G935 might not be the best option, but if you plug into your PC to get your game on, the G935 earns every cent of the $179 price tag.
