One simply becomes the subwoofer.
At the edge of fashion and experimental science, Vollebak has released the Sonic Jacket — a white puffer coat lined with 180 inward-facing speakers designed to flood the human body with sound frequencies rather than the surrounding air. Built in collaboration with Hollywood costume engineers, the garment raises an ancient question in a thoroughly modern form: can rhythm and resonance genuinely alter the inner life of a person, or does the desire to believe so simply make for compelling marketing? The answer, as with most things at the frontier, remains beautifully unresolved.
- Vollebak has embedded 180 tiny speakers into a puffer coat that fires sound frequencies — from 4Hz to 20,000Hz — directly into the wearer's body, turning the human form into a living resonance chamber.
- The jacket's visual design makes no attempt at subtlety: yellow wires loop openly across white fabric, black speaker housings dot the surface, and the whole assembly looks closer to a film prop than a coat — because, in part, it was built by the people who make film props.
- To generate ultra-low frequencies its small speakers cannot physically produce alone, the jacket plays two slightly different tones simultaneously, letting the wearer's body perceive the difference — a beat frequency trick that manufactures sensation from mathematics.
- Vollebak's marketing copy promises everything from flow states to spiritual awakening, while the scientific community offers only cautious acknowledgment that sound can influence mood — leaving the jacket suspended between genuine sensory tool and very expensive provocation.
- Priced on application and framed as concept-grade futurewear, the Sonic Jacket is less a product launch than a question posed in fabric and wire: how far are we willing to go to feel something different?
Vollebak has produced unusual things before, but the Sonic Jacket represents a new category of strange: a white puffer coat embedded with 180 inward-facing speakers, each 32 millimeters wide, laser-cut into the fabric and wired visibly across the torso, sleeves, and hood. The garment does not attempt to hide what it is. Yellow wires loop openly, black housings dot the surface, and the overall effect is less clothing than laboratory equipment that wandered into a wardrobe. The design leans into its own absurdity — anything more restrained would simply feel dishonest.
The speakers cover a frequency range from 4Hz to 20,000Hz, controlled through an onboard MP3 player, a physical tuning dial, and Micro SD storage for up to 1,000 custom presets. A Bluetooth app is in development. The jacket's most technically interesting feature is its approach to ultra-low frequencies: by playing two slightly different tones simultaneously — say, 100Hz and 104Hz — the wearer perceives the 4Hz difference between them as a felt sensation, a beat frequency effect that allows the small speakers to produce what they cannot technically generate alone.
Vollebak built the jacket alongside FBFX, a London special effects studio whose credits include Gladiator, Dune, and The Martian. The collaboration brought genuine costume-engineering craft to what is, at its core, a wearable speaker system. Co-founder Grant Pearmain acknowledged the build looks like a science experiment — because that is precisely what it is.
The company frames the jacket around sound therapy and the long human tradition of using rhythm to shift mood and perception. There is real science suggesting sound influences emotional state, and a device that delivers frequencies through the body could be a meaningful sensory tool. But Vollebak's marketing reaches further, suggesting the jacket might produce enlightenment, flow states, or something approaching the divine. Whether that ambition reflects genuine possibility or simply committed showmanship is a question the jacket leaves deliberately open — and one that can only be answered, perhaps, by zipping it up.
Vollebak has built a lot of strange things over the years, but the Sonic Jacket might be the strangest yet: a white puffer coat embedded with 180 tiny speakers, all facing inward, all firing sound frequencies directly into your body. It is, essentially, wearable subwoofer technology—a way to become the bass instead of standing next to it.
The jacket spreads these speakers across the torso, sleeves, and hood. Each one measures 32 millimeters in diameter and 10 millimeters deep, mounted into laser-cut holes and wired across the surface like laboratory equipment that somehow ended up in a closet. The visual effect is deliberately exposed: white puffy fabric, yellow wires looping visibly, black speaker housings dotted across the garment. It looks less like clothing and more like something you'd wear if you were being unplugged from The Matrix. The design owns its own absurdity—anything that tried to look normal would simply disappoint.
The speakers generate frequencies ranging from 4 hertz to 20,000 hertz, firing them directly into the wearer's body. The control unit includes an MP3 player with 10 preset frequencies built in, a large physical dial for manual tuning, and Micro SD storage capable of holding up to 1,000 custom presets. A Bluetooth-connected app is currently in development. The real trick happens at the lower end of the frequency spectrum. To produce ultra-low frequencies that such small speakers would normally struggle with, the jacket plays two slightly different tones simultaneously. Play 100 hertz and 104 hertz at the same time, and the wearer experiences the 4-hertz difference between them—a beat frequency effect that creates the sensation of frequencies the speakers themselves cannot technically produce.
Vollebak frames the Sonic Jacket around a long human history of using rhythm, sound, and frequency to alter mood and perception. There is legitimate science suggesting that sound can affect attention and emotional state, and a device that vibrates these frequencies through your body could genuinely be an interesting sensory tool. But the company's marketing copy ventures into wilder territory. The official description suggests that wearing the jacket might produce enlightenment, flow state, or some kind of audio-induced spiritual experience. "Maybe you'll orgasm. Maybe you'll shit yourself. Maybe you'll find God," the copy reads. Whether that's transcendence or just extremely committed bass remains an open question.
To engineer the jacket, Vollebak partnered with FBFX, a London special effects studio known for building costumes for major film and television productions—Gladiator, The Martian, Prometheus, Dune. The studio brought its costume-engineering expertise to what is essentially a wearable speaker system. Grant Pearmain, FBFX's co-founder, noted that the construction looks like a science experiment because that is what it is. The build quality is impressive, even if the claims around consciousness and frequency might strain credibility.
Vollebak lists the Sonic Jacket's price as available on application, which seems fitting for a wearable frequency chamber built by the people who engineer Hollywood spacesuits. It is clearly positioned as concept-grade futurewear rather than something for everyday use. The jacket is strange, visually striking, and several steps removed from having an obvious practical application. Whether that represents genuine progress or just an expensive way to become the bassline depends entirely on who you ask—and whether you're brave enough to zip it up and find out.

La Conversación del Hearth Otra perspectiva de la historia
So this is a jacket with 180 speakers sewn into it, all pointing inward. Why would anyone want that?
Because most sound technology pushes outward—headphones, speakers, earbuds. This reverses it. You're not listening to the sound; you're feeling it vibrate through your entire body.
But can your body actually perceive those frequencies? Isn't that just vibration?
That's the interesting part. Yes, it's vibration. But vibration is how we feel bass in a concert, how we feel rhythm in our bones. The jacket is just making that the entire experience.
The company mentions enlightenment and spiritual experiences. That seems like a stretch.
It is a stretch. But there's real research on how low-frequency sound affects the nervous system and mood. Whether this jacket actually does anything beyond feeling strange—that's untested.
Who would actually buy this?
People who collect experimental art, people curious about sensory experiences, maybe sound therapists. It's priced on application, so it's not a mass-market product. It's a statement piece.
What's the most honest thing about it?
That it looks exactly like what it is—a science experiment. No pretense. No hiding the wires or speakers. That honesty is actually refreshing.
