In case there are some headset standards that I am ignorant of, let me preface this by saying that I bought this purely for general purpose work and browsing on two computers (work and personal) with rare gaming use, coupled with Bluetooth audio for my phone. I don't have, and have never tried, gaming headsets so I am mostly comparing these to high-end Bluetooth ANC headphones (Bose and Sony).Pros:• Cleanest audio I have ever experienced from a wireless headset, felt on par with the Sony WH1000XM3's for music (even a tad better with Tidal on Windows) but blew away anything using Bluetooth when used for Dolby Atmos movies and games (see cons for plenty of caveats...).• Dual audio with my phone and computer is tech bliss, never knew how much I would appreciate being able to just answer a phone call while listening to some background work music.• Wireless range is stellar• Dual battery setup is a nice touch of convenienceCons:• Bad EQ out of the box! I can see the incredibly tinny sound being useful in games when you want to accurately locate stuff but it makes vocals in ANYTHING sound like they were recorded by a budget headset. The plosives and sibilance (strong hisses and 's' & 'p' sounds) made me think I had gotten a broken unit. I had to spend a few hours tuning the EQ (first through Sonar then in Engine, more on that below) to make them sound more natural to me (current EQ settings attached, my bass level might be slightly above pure flat but I enjoyed content better with the slight oomf).• Clamping force is painful out of the box! I almost returned these because of this one, I wear glasses so using these for more than an hour straight would become unbearable. I partially solved this by stretching them out over my chair at night (to do this safely, place them on anything that is slightly wider than your head when not using them), they loosened up in a few days. The other reason was the weird dual adjustment of the strap and headband. I initially kept the band as close to the plastic headband so they were less noticeable on my head but by treating them like any other headset, I ended up placing too much pressure on my jawbone, instead, it’s best to apply what might feel like a slightly uncomfortable degree of pressure on your head (this becomes unnoticeable after a while, turns out SteelSeries knew what they were doing with this ski band thing), this relieves the pressure on your ears.• Sonar is garbage for anything outside of games. It has some saved EQ presets for various games but I’d rather have my dialed in settings for everything, so I ignored all that. Their virtual surround makes anything besides games sound unnatural. Dolby Atmos for Windows sounded leagues better by knowing when to leave the audio as is and when to simulate that surround effect. I know you have to pay for it on PC but the one-time fee was more than worth it to me. The only Sonar feature that was useful to me was their AI Voice for the microphone, it makes a huge difference in cleaning up the audio. Unfortunately, Sonar deeply compresses your audio (output and input) effectively negating any point of spending top dollar for “Hi-Res Audio.” I tried getting the Sonar for Mic working without Windows constantly switching me over to the compressed audio output as well, in the end I just gave up on it and turned it off.• ANC is pretty bad; it’ll dampen an A/C, exhaust or low-hum traffic but Sony, Bose and Apple are in a completely different league. The minor noise reduction it offered was almost never worth the added ear pressure for me (if you have never used ANC, turning it on feels like a subtle version of a plane’s incline/decline on your ears). The passive isolation is still pretty good though.• Build quality is pretty meh for the price. You would expect plusher padding and better feeling plastic but nope. They never creaked on me though, so their longevity feels solid.If you stuck around till here congrats, I hope I gave you a clearer picture of these compared to any of the reviews I had seen on them. I had to work really hard to love these, something I had never had to do on a premium sound product before (besides a brief trial of the Penrose) but I can confidently say they’ll be my daily drivers for years.
