Vollebak’s Sonic Jacket is closer to a wearable prototype than a conventional piece of outerwear. Developed with special-effects company FBFX, the garment incorporates 180 small speakers facing inward across the torso, arms, and hood, creating a field of sound intended to be heard and physically felt through the body. The speakers are integrated into the fabric with visible yellow wiring, making the jacket look as experimental as its premise. Vollebak has connected the project to ideas around vibration and sound therapy, but the most convincing way to read it is as an interface experiment rather than a medical device. What happens when sound is distributed across clothing instead of delivered through headphones or a room? The prototype makes that question tangible, using the body itself as the listening environment and turning fashion into a platform for spatial audio research.
One Hundred and Eighty Speakers Change the Scale
The Sonic Jacket begins with an absurdly large number: 180 speakers, each approximately 32 millimeters across, arranged over a garment. Unlike a portable speaker designed to project outward, these drivers face inward. Sound is distributed directly across the wearer’s torso, arms, and head, creating an experience closer to vibration and immersion than ordinary personal audio.
The configuration changes how listening is imagined. Headphones concentrate sound at the ears, while club systems move air through an entire room. Vollebak’s prototype places the source against the body. Different areas can theoretically become channels, allowing low frequencies or directional effects to be mapped physically. The jacket is therefore less interesting as “clothing with speakers” than as a wearable sound field whose geometry is determined by anatomy.
FBFX Brings Costume Engineering to the Problem
Vollebak developed the garment with FBFX, a company known for complex costume and special-effects work on major film productions. That partnership makes sense because integrating so many components into clothing is as much an engineering problem as a fashion one. The system has to flex, carry wiring, distribute weight, and remain legible enough to test and repair.
The visible yellow wiring is a smart aesthetic decision because it refuses to pretend the prototype is finished consumer electronics. The circuitry becomes part of the visual identity, making the jacket look like a test rig that happens to be wearable. In speculative design, that honesty can be more persuasive than polish. Viewers can see the complexity rather than being asked to imagine that 180 speakers have somehow disappeared into an ordinary shell.
Feeling Sound Is Not the Same as Proving Therapy
Vollebak has discussed the project in relation to low-frequency vibration and sound-based wellness practices. There is a long history of using vibration in therapeutic and relaxation contexts, but the existence of a vibrating garment does not by itself establish clinical benefit. Any medical or wellness claims would require careful evidence, controlled testing, and clarity about frequency, intensity, duration, and individual conditions.
The Sonic Jacket remains compelling without such claims. As a design experiment, it asks how tactile sensation can become part of audio. Bass is already felt as well as heard at concerts; haptic motors in phones and game controllers already translate information into vibration. A garment covered with full-range drivers expands that familiar principle into a continuous surface. The research value lies in the interface, not in promising an outcome it has not yet demonstrated.
Fashion Becomes an Infrastructure Layer
Wearable technology often fails when electronics are treated as accessories clipped onto clothes. The Sonic Jacket takes a more integrated approach: the garment itself is the carrier for power, signal, speakers, and spatial positioning. That makes pattern cutting and component placement part of the audio design. A sleeve is not only a sleeve; it is a location in a distributed acoustic system.
This approach could eventually influence applications beyond entertainment. Navigation cues, performance art, gaming, accessibility interfaces, or remote communication could all use localized vibration and sound across the body. The current prototype does not need to solve those use cases. Its contribution is showing that clothing can become infrastructure for information, with the body receiving signals across a far larger surface than a watch or earbud provides.
A Prototype Is Allowed to Be Strange
Vollebak has built a reputation around speculative garments that test unusual materials and technologies, and the Sonic Jacket fits that pattern. It is not easy to imagine 180 speakers becoming a mass-market wardrobe essential. But judging every prototype by immediate commercial practicality misses the point of experimental design. Strange objects can expose possibilities that later become simpler, cheaper, or more focused.
The jacket’s most useful achievement is conceptual clarity. It makes wearable audio impossible to think about only at the ear. Once sound can be placed across the chest, back, arms, and hood, designers have to consider choreography, mapping, and bodily attention. The garment may never become ordinary—and perhaps should not—but it expands the territory. Fashion becomes not merely what covers the body, but a programmable layer through which the body can receive an environment.
The Jacket Raises a Question About Where Personal Audio Ends
Headphones create a private sound field by sealing music close to the ears. A garment filled with speakers proposes almost the opposite relationship: sound becomes distributed across the body and potentially audible beyond it. That shift turns audio from an accessory into an environmental layer, raising questions about privacy, immersion, and how vibration is physically experienced.
Vollebak’s experiment is most interesting as a prototype rather than a promise that everyone will soon wear 180 speakers. Extreme objects can make hidden assumptions visible. Why do speakers normally sit in a box across the room? Why does wearable audio concentrate around the head? What changes when the torso becomes the platform? The sonic jacket tests those conventions at exaggerated scale. It also sits within a longer history of fashion trying to absorb technologies that usually remain separate from clothing. Many such experiments never become everyday products, but they can still influence how engineers and designers imagine interfaces. Here, the body is not merely carrying a device in a pocket. It becomes the surface through which sound is organized, turning listening into something closer to inhabiting an instrument.
