Whatever you do, don't go for an office that has a "noise suppression" system in it. A company that I used to work for has one, when I first joined I thought it was just a loud HVAC system (until I was informed what it really was). It took a lot of getting used to, or so I thought, then the headaches started coming. Headaches that would start at work and then dissipate an hour or two after leaving the office. After doing some reading and discussing with a relative who designs buildings for healthcare, I realized the connection between the two. I started working from home, no headaches. Apparently a not insignificant percentage of people have this reaction to a constant "barely audible" white noise. I'm not sure if I would have the same reaction to the headphones, but at this point I'm not trying it.
