That's only if you like to listen to music while you work. If you just want quiet, get yourself a pair of the earmuffs that the airport ground crews wear out on the tarmac. I had a coworker who wore those and the only real downside was that he'd get horribly startled when people were trying to get his attention because they'd have to come up and touch him on the shoulder. Even basically yelling in the vicinity of his ears, he'd have no idea people were right behind him.
I have an older noise-cancelling model, the QC 15s, and they do a decent job at noise cancelling even without music. I listen to https://www.brain.fm/ (paid, but lifetime license is cheap) at a low volume to drown out any remaining noise. It's consistent background "white" noise that drowns out even the loudest co-workers. Wear them for 6-10 hours / day, best productivity investment I've ever made.
Can't you just use a pair of noise-canceling cans without piping audio through them? Is there a drawback to turning on the noise-canceling feature without coming through the speakers? It won't be completely quiet (on basic models), but it is probably comfortably quiet for most.
