Frequency Technology You Wear 24/7 | Dimitri, The One Device

At Biohackers World, Josh sits down with Dimitri, creator of The One Device — a frequency wearable that layers infrared light, visible light, and sound into one small pendant designed to bring your nervous system back to balance.

They cover the science behind it, the results of its first study (~90% reported less stress and better sleep), how Josh uses it 24/7 in circadian mode, and why he calls it a tuning fork for your energy system.


5 Key Takeaways
• The One Device combines infrared light, visible light, and sound pulsing at the same frequency — plus two vibrating crystals — so the effect is far greater than any one modality alone.

• Modern life (Wi-Fi, screens, toxins, stress) pulls us out of the balanced state where our sympathetic and parasympathetic nervous systems are in sync. The device helps you return to that state.

• The device doesn't "do" the healing — your body does. It simply creates the conditions of coherence so you have the resources to rest, digest, and repair.

• Its first study showed ~90% of users reported noticeably less stress, better sleep, more calm, and more focus.

• A copper Faraday-cage body means no Bluetooth and no EMF escape; the app syncs through vibration, and modes like circadian and voice/HRV analysis let you personalize it.

This episode is brought to you by the very thing we're talking about — The One Device.

I didn't come to Biohackers World because I had to. I came because I actually wear this thing every single day. As a biohacker, I've tried a lot of tools you have to take on faith. The One Device was the first one that looked good on me — a real conversation piece — and the first one where I could actually see a light being emitted, so I knew there was something happening beyond just "energy."

What keeps it on my neck 24/7 is coherence. I fly constantly, I live in the middle of New York City, and I'm big on sensory awareness — I'm even writing a book called Sensory Movement. Keeping The One Device in circadian mode helps me stay in that balanced, rest-and-digest state a whole lot longer, no matter where I've landed. It's a tuning fork for your nervous system, sitting right over your heart.
