Who really is an Audiophile? And, how do you become one?

One of the things that I get so often is – who is an audiophile? What does that even mean? And do you need to be an audiophile to start using and listening to music on high-end headphones and IEMs? I don’t know if there’s a text definition for an audiophile that I like, but I’ll tell you what I think about it.
