Most headphone cables are an afterthought. They hang off the ear cup, snag on bags and collars, and add little to the design beyond carrying sound. Jojo, a wired headphone concept from All Design Lab, gives the cable a structural job. The cable forms the headband, and the fit changes by rotating the ear cups rather than sliding them.
The concept does not try to hide the wire. It asks how much of the product the wire can become. That question leads to a clear headphone design: two ear cups with black foam cushions, joined by one cord that runs without interruption between them.

Inside the wired headphone concept
The path starts at a USB-C plug and passes through an inline remote. From there, the cable enters the first ear cup, arches over the head as the headband, and winds into the second cup. The “single cable” description refers to this continuous route. The headphones still contain drivers, cushions, covers, and an internal adjustment mechanism.
The yo-yo comparison describes the interaction. Turning an ear cup’s outer cover winds cable in or lets it out, which changes the length of the headband. Instead of pulling an arm out of a housing, the wearer rotates a disc beside the ear.
A ratchet inside the hub provides stepped adjustments and holds the cable at the chosen length. The cushion is designed to stay still against the ear while the outer cover, hub, and driver turn together. Without that separation, the foam would drag across the ear with every adjustment.
The proposed materials match the mechanism. A braided textile cable would read as a cord rather than a rigid band. Frosted translucent covers would offer a partial view of the parts inside the cups. Black foam cushions keep the contact surfaces visually straightforward.
The inline remote follows the same restrained approach. It holds a microphone and a volume rocker, which keeps the ear cups focused on fit. Separating the controls from the adjustment also avoids confusion, since rotating the outer covers is the design’s defining action.
The practical question is how a narrow cable behaves as a headband. It needs enough stiffness to hold its arch and position the cups. It also needs enough flexibility to wind around the hubs. The concept description does not show how much pressure the band applies across the top of the head, or how securely the cups stay in place during movement.
Repeated winding raises further questions. The cable carries electrical signal and bears structural load, so its bending performance affects reliability as well as appearance. A continuous cable also complicates repair. If one section fails, replacing it may not be simple. These are development questions, and they are worth answering before the idea moves forward.
Jojo remains a concept, not a tested product. Its strongest feature is the adjustment itself: a small twist that visibly changes the fit. If that gesture feels dependable and the headband stays comfortable, the cable will have earned its prominent place in the design.
For a contrast, Sony’s revived WH-1000XM4 headphones with subtle upgrades show how a familiar design gets refined rather than reinvented.

Frequently asked questions
How does Jojo adjust the headband fit?
Jojo changes fit by rotating the ear cups rather than sliding them. Turning an ear cup’s outer cover winds the cable in or lets it out, which changes the headband’s length.
What path does the Jojo headphone cable take?
The cable starts at a USB-C plug and passes through an inline remote. It then enters the first ear cup, arches over the head as the headband, and winds into the second ear cup.
Does the Jojo cushion rotate with the ear cups?
No, the cushion is designed to stay still against the ear. The outer cover, hub, and driver turn together while the foam remains in place, which prevents it from dragging across the ear during adjustments.
Is the Jojo headphone concept a finished product?
No, Jojo is a concept rather than a tested product. The article notes that questions about bending performance, pressure, and repair still need to be answered before the idea moves forward.
