Soundcore Liberty 5 noise-cancelling wireless earbuds. £75, so $100ish. Saved my sanity when the infrastructure team decided to set-up a rack mount server in my office "just for a few days, honestly" and I spent two weeks listening to the system fan spooling up every (count them) seventy five seconds. The sound quality is pretty good too.
