I recently reviewed my first-ever hi-res headset in the Arctis Nova Elite, and the algorithm must've known I was keen to explore this segment even more.
The hi-res certification is issued to headsets that meet a certain quality criteria, revolving around things like 40 kHz audio ranges and 24-bit streaming standards. Some aspects of the certification could be described largely as a marketing gimmick, particularly with audio frequencies that fall well out of the range of human hearing capabilities, but it does represent a family of specs that do contribute to a better overall sound experience, at least in general.
