The One Device — wearable frequency + light + sound pendant — A jewelry-style wearable that delivers infrared light, micro-vibration/sound and crystal-activated resonance throughout the day to support sleep, stress resilience, recovery and HRV. Worn on the body, in the environment, or by the bed; charges via USB and intentionally emits no Bluetooth / no EMF. Learn more: https://theonedevice.com/joshuahollandUSE CODE: JOSHSUMMARY:Joshua talks with Dmitri Leonov about The One Device — a jewelry-style wearable that blends infrared light, subtle sound/vibration and crystal resonance (no Bluetooth / no EMF) to support sleep, HRV, stress resilience and daily presence.5 KEY TAKEAWAYS• The One Device combines infrared light, subtle sound/vibration and activated crystals (clear quartz + shungite) to provide continuous, low-intensity “whisper” therapy rather than occasional, intense sessions.• Wearing subtle, persistent frequencies throughout the day helps maintain a resonant baseline so the benefits of therapy are less likely to dissipate when returning to daily life.• The device intentionally avoids Bluetooth/EMF and is plated in metal (copper base) to minimize emissions — design choices were driven by user priorities and measurement.• Practical use tips: tap to cycle modes, wear against skin for strongest effect (but hanging near the bed or in your environment can still help), long battery life, water resistant (not fully waterproof).• Early signals from users and internal testing show improvements in HRV and increases in theta (meditative) states; some users note rapid symptom relief for pain, improved PMS, and better sleep — company offers a 90-day guarantee.TIMESTAMPS00:00 START — Episode opener & guest intro (Joshua introduces Dmitri).00:02 — Dmitri’s short bio: serial entrepreneur, wellness tech, mission to scale human thriving.02:13 — First hello from Dmitri; setup for demo of the pendant.02:27 — Josh: first impressions — wearing the pendant continually, where he wears it.03:15 — Dmitri: recent travels (Asprey conference) and context for the product.04:07 — Josh: voice issues and how that shifted his thinking — small personal moment.05:37 — Dmitri: origin story—tech and wellness background, why he built the device.14:06 — Evolution of the technology; from passive materials → active, rechargeable device.20:23 — Battery life and continuous-use claims — discussion of practical use.21:45 — Design choices: volume, light brightness, user testing and iteration.34:10 — New feature: bio-tuning with HRV to find personal resonant frequency (clinic-based today).36:54 — How bio-tuning works today (centers in NY/LA/SD/UK) and plans for at-home programming in 2026.39:25 — Discussion about competing devices (Sense8, Apollo, others) and One’s focus on light + sound.48:37 — Product positioning: calm, focus, sleep, HRV, recovery — how it resonates with users.54:35 — Who’s the early adopter and where the company sees product-market fit (mostly US).1:12:59 — How to get in touch: theonedevice.com (customer support responsive).RESOURCES MENTIONED• HumanTechWeek (events / summits referenced by Dmitri): https://humantechweek.com• Dave Asprey / Business of Biohacking (conference referenced): https://daveasprey.com (search “Business of Biohackin🌐 Connect with Joshua & SWTT Podcast Website: https://www.simplywalkthetalk.com YouTube: @simplywalkthetalk Instagram: @simplywalkthetalk TikTok: @simplywalkthetalk Joshua Holland: https://linktr.ee/joshuajholland
