I did quite a bit of research online before purchasing these. Coming from a Hyper X Revolver (stereo) headset, I was looking for an upgrade in fidelity that would also have some of the features that I like with other gaming headsets. Closed back was a big one for me, which made my search slightly more challenging. Many headphones in this range are open back, and I didn't want much sound getting in or out. These are planar drivers, not cone. I won't go into much detail other than to say these type of drivers produce a cleaner sound than dynamic or moving coil. The downside is they require power. This headset has a battery inside, which means it requires power. I have them connected via usb-c to my pc, but when connecting over analog you will have about 8-10 hours of listening before they need to be charged. You can hear them turn on, but when audio is playing you can't hear it. I'm trying to hear it as I type this with tv on my other screen. I could do without the headset telling me when I've muted, charged, or changed modes, but it's nice to know sometimes. It would be a nice option to turn that off. Microphone sounds good, plenty loud, and a mute switch is right on the headset, no in-line controller which is a plus imo. Mic is also detachable and has independent volume control also on the headset. Most of the buttons and wheel have multiple functions and may take some time to get used to. 7.1 and 3d mode both work well. I still prefer stereo most of the time but it's nice to have options...some games or movies sound really good in surround, but it depends on the source. Head tracking is pretty neat, and would be perfect paired with a vr setup. Looking at a flat screen you don't turn your head enough for them it to be practical...but it certainly works as advertised. Hi-Res audio mode is only available on pc, and is the best sounding mode on the headset. Stereo sounds good still when connected to your phone or game controller. It's definitely heavier than my old set, and fits a bit tighter. It was almost alarming how loose my old set felt after wearing these for the last three weeks. These are comfortable, thick ear and band pads feel nice, but they do clamp. If you are sensitive to pressure, you may find some discomfort. The band is adjustable and the cups turn and swivel. In conclusion, they sound amazing and they were well worth the price for that reason alone. They fit snug, which doesn't bother me but could bother some. This headset will connect to a variety of devices and offer convenient options. I don't really use the software, though like I mentioned before would be a great addition to a VR setup. If you want high quality audio with great features and no additional equipment, it's hard to find a better set. They're not wireless, but I wasn't looking for that.
