Koss KPH30iK Retro Style On-Ear Headphones, in-Line Microphone and Touch Remote Control, D-Profile Design, Wired with 3.5mm Plug, Dark Grey and Black

Koss KPH30i, which retail usually for $30 but can sometimes be bought on sale. These are ludicrously high quality for the price and outperform a lot of $150-200 headsets in terms of sound quality. These look like library ass headphones and there is no noise cancelling whatsoever, and they're somewhat fragile, but the sound quality these put out have floored a lot of audiophiles for a few years now. They're god tier for the price. https://www.amazon.com/Koss-KPH30ik-Headphones-Microphone-Lightweight/dp/B075FBRYM1/ Koss KPH40 are an alternative for $40 that sound almost identical(some audiophiles still prefer the KPH30i) but the cable is swappable in case you care about that.
