What if I want to listen to music, but I don't mind someone talking to me if they need something? What if I want to concentrate with no interruptions, including no noise/music from headphones?
For me - I like having headphones on without music because it's kinda warm and lowers outside noise. If I want to listen to something and still indicate I'm available to chat, I only have one headphone over the ear and the other to the side.
