I'm going to give the advice here that saved my sanity in an open office: use headphones with "passive" noise canceling. I bought a pair of 3M WorkTunes with Bluetooth. They're just passive, sound deadening, hearing protection ear muffs like you would wear on a factory floor or in a construction workplace, with Bluetooth built. It blocks out all noise, not just white noise, and they're much cheaper than ANC head phones.

I wear the WorkTunes, plus ear plugs, plus I play cafe or brown noise through the headphones, plus I sometimes put on music. If that hadn't worked, I was going to go insane from the sound of the keyboard next to me.
