A headset with many flaws, difficult to explain given its price.
As soon as I received the headset, I had a number of problems with wi-fi desynchronisation.
With successive resets and uninstallations/reinstallations of drivers and related software, this problem eventually became relatively rare.
After that, I repeatedly encountered problems with the headset disconnecting when it was at 70/80% battery and it didn't warn me of any form of discharge or low battery. Annoying, but tolerable nonetheless.
Finally, after just over a year, it's now the mute button that remains stuck in the mute position, preventing me from using the cable normally.
It was my first Steelseries, I was disappointed by the quality of the microphone, the quality of the audio (although I was used to comparable levels, coming from a Logitech G935), disappointed by their software, disappointed by the random battery and the wi-fi sync problems, now disappointed to have bought a headset at this price, only to have to throw it away a year later.
I wouldn't recommend buying the Arctis 9 and I don't think I'll be buying Steelseries products in the future.
