They are comfortable Battery lasts quite some time between charges Audio is great Very noise cancelling

Range is weak. No side tone (combined with the noise cancelling makes it disorientating for me) Bugs? Glitches? Errors? I've had repeated issues with them, and currently the audio keeps dropping in and out.

I had Corsairs cheaper headset for years. Loved it, but due to constantly moving I lost the USB for it. Figured the step up has to be better right? Wrong. Some of it is personal opinion, like the lack of side tone. But I have had other issues, mainly with audio dropping in and out, software dumping your settings, the fact that when it's plugged in it has a completely different set of settings than when you're wireless, and the range is extremely weak. For the cost of the headset it is far to mid tier to be that price. If it was cheaper I would give it a higher rating. The battery has lasted and the build quality is still going strong. But its performance is just not worth the cost.

Was good initially the first 2 weeks.

The left side of the headsets volume started bugging out, being lower than the right side making listening experiences very uncomfortable, and then not even a month of use it stopped working.

I don't know if the product is just old but it was good when it worked.

This is hands down the best wireless headset on the market. The headset is made of premium materials and is extremely comfortable for a full days worth of use. The microphone is by far one of if not the best microphone on a wireless headset. Sound is excellent for my use case of gaming and general productivity, I used EQ settings from a YouTubers review (The Techne). USB C is a big plus for me. Battery without the LEDs on is easily more than a days use. LEDs are nice however turning them on will reduce battery life, from my experience having the LEDs on the low brightness setting I still get most of days use depending on volume and use case. Wireless range is more than enough for me and most likely for most people. Corsair icue works just fine. This headset just checks every box for a wireless headset, its by far the most well rounded device right now.

Not something to take away from the headset itself but something to note, for whatever reason Corsair sends some of these headsets with a default microphone input setting of -6db, which will cause it to be very quiet. This however can be easily fixed by using a application called Equalizer APO, simply watch a YouTube tutorial on how to use it and set the mic to pre-amplification of +10db and your set. Not sure why Corsair hasn't fixed this yet as it may cause some confusion for someone who isn't very experienced in troubleshooting or solving technical problems.

If you are in the market for the best wireless headset, look no further than the Corsair HS80. This will hit every major headset check list from the excellent sound to excellent microphone quality to being the most comfortable headset I've ever used. If you happen to get a model with the weird mic settings just use Equalizer APO and it will be perfect. Highly recommend.
