While some shady manufacturer could probably claim to have “the world’s first interactive headphones” by say, slapping a Facebook Like button on them, the Beyerdynamic Custom One Pros ($195) thankfully go several steps further than that. These customizable cans let you change the sound and style to match your needs. Sound sliders control the flexible bass reflex vents on the earcups pads, letting you go from “Nice bass!” to “WHY ARE MY EYEBALLS SHAKING?!” in a matter of moments. The rings, covers, and cushions on the ear pads are also interchangeable, along with the cushioned headband.
