The World’s First Heart-Synced Ferrofluid Headphones
When tech touches soul, rhythm comes alive.
Equipped with high-precisionPPG optical sensors, Levi is more than just headphones—it detects your emotional ebbs and flows by monitoring your heart rate (BPM) and Heart Rate Variability (HRV) in real time. By activating the "Dopamine Sensing Mode," you unlock a uniqueSensory Symbiosisdriven by thedual synchronization of ferrofluid and light (Liquid & Light Sync).
Powered by a self-developed mapping algorithm, the ferrofluid’s morphology and lighting colors shift instantly according to your inner state:
Deep Calm Mode: When you are relaxed, the ferrofluid flows with silky, water-like grace, paired withlow-saturation "breathing" lightsto guide you into a deep state of flow.
Peak Power Mode: When you are excited, the ferrofluid transforms into a "spiked" formation, pulsating withhigh-frequency lightflashes that leap in sync with your racing heart.
Biofeedback Interaction
Levi creates a proprietary "Life Resonance,"giving every song a soul that breathes in harmony with your own pulse. It is your companion in solitude and your healer in times of stress. It doesn’t just play music; it resonates with the very rhythm of your life.

Ferrofluid-Driven Real-Time Visual Headphones
See Your Music in Real-Time Fluid Art
Most headphones only let you hear the music. This time, you can watch it come to life. Inside Levi, a specialized substance known as ferrofluid reacts instantly to sound. Driven by a precision electromagnetic system, the fluid pulses and flows in sync with every beat, transforming low-frequency vibrations into visible dynamics.The melody doesn't just play—it breathes.
Every rhythm leaves a trace; Every beat is crystal clear.Originally developed by NASA for fluid control in zero-gravity environments, we have integrated this space-age technology into our headphones. Combined with our proprietary Rhythm Algorithm, we’ve given sound a visible form like never before.Put them on, press play—don’t just listen to the music, watch it flow before your eyes.

Team Story
We’re a small team of designers and engineers, always asking one question: does music have to be only something you hear? In a world where audio products are becoming more and more similar, we wanted to create something different — an experience where music is not just sound, but something you can actually see.
LeviSound is inspired by the natural motion of ferrofluid. We explore how sound can be transformed into visual movement, so every beat creates a real-time shifting rhythm. After multiple prototypes and tests, we turned this idea into a wearable pair of headphones.
It’s more than just headphones — it’s a new way to experience music, where sound, motion, and futuristic aesthetics come together. We’re bringing LeviSound to Kickstarter to build it together with people who believe in new ideas.
