Featuring an "interchangeable cording system" that allows for switching between audio-only and phone-compatible cables, these headphones come in two 70s-inspired styles -- a square ear cup model based on the decade's Hi-Fi studio monitor pieces, and a circular ear cup that "refers to 12-inch vinyl record textures, with a metallic material finish that identified the premium audio equipment of the era", because Dionne Warwick deserved no less.
