You're right. However, in most cases a lowly worker bee in an office environment doesn't really have too many options. Several years ago I was in a really bad office noise situation and I went out and bought Bose QC-15 headphones for $300. It was the best $300 I ever spent. I still have them and I still regularly use them in my home office. When they break, I plan to buy another pair.
