I once used wired ($200?) Sony noise cancelling headphones to listen to music in the office (and on airline flights). They wore out a few years ago, and instead of replacing with another pair of big $ NC headphones, I bought "Sentey LS-4560 B-trek H9 Bluetooth Wireless Foldable Headphones with Carrying Case" for $40[1]. They obviously don't noise cancel, but since I listen to music anyway, and get great non-cancelling isolation from the new phones, I don't really miss the NC aspect; the only place where I believe NC is dramatically superior to these headphones is on airline flights. And I take so few of those these days, I can't justify the expense. [1] https://www.amazon.com/gp/product/B00PYW5X1A/ https://www.amazon.com/gp/product/B00PYW5X1A/
