Earbuds

It's amazing the difference in the sound quality you get with a decent pair of earbuds. These are a must for working for me anyway. I stick them in my ears and go to it. The music helps me focus on what I'm doing and helps to tune other noises around me out. And also, it's suppose to discourage my co-workers from trying to chit chat with me. When I have the earbuds in most of the time they keep on walking by my office.
