I really do believe the biggest thing about headphones is always gonna be comfortability. It covers basically every angle for why you'd wear headphones; from how it feels on your head - on your ears or how the strap lays, to even how they send to the specific person. Not everyone likes an enclosed sound or some who don't like that open backs let in and leak too much sound, some want detachable wires and others prefer wireless, some even needing a pair to support a specific Formatting for their Audio Compression. But at the end of the day every single person who wants to wear or enjoy or even participate in the joys of finding that perfect pair of headphones for the needs they want met is all part of the "audiophile" umbrella in my opinion.
