Why I own 4 different pairs of headphones, and how I effectively use each one

I love headphones and earbuds. I have many of the latest models and some old favorites that I play around with in between testing new releases to review for work, making me the go-to "headphones person" for my friends and family. After a brief interrogation about their needs and a short pep talk about potential splurging, I find myself recommending four models the most.
