Owner of the headphones for a week now, coming from Razer (Nari Essential). In terms of construction, they are all plastic, but that doesn't mean they are of low quality. They are very lightweight and do not creak. The ear cushions are comfortable (memory foam) and do not press on the ears. Personally, I wear glasses with a thick frame and there is no pain from pressure. The sound quality is good, nothing special, but compared to the Razer, the Logitech has a cleaner sound and the mids and highs are not "muddy" or "drowned out" by heavy bass, which impressed me, so I would say the sound is the highlight of these headphones (based on my experience with the Razer). The support for 24bit audio is a plus. In gaming, I was able to distinguish from which direction the opponent was coming from their footsteps and in general, they have a good soundstage; you can distinguish the positions of vehicles, airplanes, gunfights, etc. The microphone is built-in and does its job; it's not for podcasts but for Discord calls it's just right. The ghub software is simple, without many frills, and stable without bugs. The buttons are ON/OFF, Bluetooth/Lightspeed, Mute (it has a distinct texture, which is good), Volume. Overall, it's a good all-rounder, it's very hard to think of something negative. If I find something, I will come back.
