Disclosure: I have thing for old skool headphones.
It’s easy to trace. I clearly remember popping on my mom’s old, plastic 70’s set on my head to listen to her hi-fi receiver… maybe play a few of her records. There was a ritual, a respect to carefully removing the vinyl, gently placing it on the table, placing the needle down with feather-light touch, as not to scratch the precious music. (I know, this coming from the girl who’s dropped her mp3 player countless-times.) Then putting on those headphones and getting lost in that all encompassing sound.
Anyway, I’ve got great associations with retro-cans, and apparently I’m not the only one.

Panasonic RP-HTX7
These are almost exactly what my mom had. And aren’t they ADORBS?
There’s also a red pair:

Which, sure, look like something you’d find on the firing range but I don’t care. The wire cup mounts give me pause, I’m sure they don’t travel well, but just cute as hell.
JVC has a pair that is a more current interpretation of the look, I’ll post that soon.

ETA: Oh looky here what I stumbled across at Apartment Therapy’s Unplugged.
My picks are here, although after two days straight of sweltering 100+ degree heat I’m glad to have buds, as ear sweat is not the business.
