Like that of work
I bought it as part of my teleworking arrangement with Covid, and it has allowed me to participate in meetings without worrying about my neighbours hearing what I wanted to say.
Outside of work, it also allowed me to play online role-playing games in the same conditions (on another computer).
In short, did the job (allowing to talk without worries) without hurting my ears (even if it was hot in the height of summer ^_^ ?
