Once I heard music from a pair of high quality headphones when I was a kid, I knew I just needed some. It was so long ago I can't remember the model, but they were circumaural and made in the 80s, I think they were Panasonic possibly Technics. Distinctively, I remember they had 1/4 inch plug only and and 1/8 adapter!
I remember thinking that it sounded like I was right there with the musicians, like an auditory hallucination. From then on I knew I needed cans that were honest and pure.
