If you're the sort of person who thrives in a quiet atmosphere or is really sensitive to sound, I can't recommend Bose QC-15 noise canceling headphones enough.

If you're the sort of person who thrives in a quiet atmosphere or is really sensitive to sound, I can't recommend Bose QC-15 noise canceling headphones enough. They've totally transformed my life and I still lament for the days of productivity I lost while living in ignorance of their existence. Even when I'm not listening to music, they take the edge off of the all the sound and noise around me so that even conversations happening within earshot aren't distracting, even though I could tune in and understand what people are saying if I wanted to. It's pretty amazing.
