I was thinking less about if they're high-end, but just the general type of headgear. It's like when you see people outside, you notice their clothing and make an inference about them from it. Like clothes, it's not always about the cost.
Think about following people if you saw them on the streets, bus, train, etc. with...
Bose, Skullcandy, or one of those rapper headphones.
A headphone available locally (Sony, JVC, Sennheiser).
A headphone not available locally (Depending on where you live, examples may include Superlux, Grado, and Audio Technica).
A modded headphone.
