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.

SUMMARY:

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.
