I became intrigued after hearing your appearance on Sean McCormick’s Optimal Performance podcast. When I later saw Sean wearing it, I reached out to ask how he liked it. His response was simple: “Get it.” I’ve been using it for about a month now. The effect is subtle, but noticeable from the moment you put the necklace on. Wearing it feels very intentional—almost like part of a personal practice. If you’ve ever done a float (sensory deprivation), it gives me a similar post-float glow. Placing it on my bedpost at night also seems to support much better sleep for me. After a few weeks, you start to notice the moments when it’s not on your body—almost like a reminder to wear it. Recently, I’ve noticed that the necklace holds the most value for me after meditation, and especially after a float session. Paired with that post-float glow is where I’ve felt the strongest effect (yes, I’m calling it that). I’ve now worn it before and after two float therapy sessions. Last night, during a float, it felt like I unlocked something additional. I had a transformative vision in which it became clear that this necklace is a powerful tool. As I exited the float tank, I saw my necklace hanging from a coat hook. When I put it on, I felt a strong sense of energy and connection between my body and the device. I’d love to talk more about this with the folks at The One. There seems to be a meaningful connection between float therapy and The One as a supportive aid that I don’t think has been discussed yet. Update: Wore the One to a concert this week. Absolutely feeling a serious grounded connection or centering of the music with my body. Again, heard to describe the feeling but this one was strong. Beautiful stuff here!

⭐️⭐️⭐️⭐️⭐️ A Beautiful Shift for My Daughter with the ONE Device My daughter, Amelia, has been wearing the ONE Device — the wearable, heart-crafted bio-tuning necklace made by ONE Technologies in Miami — and the shift in her has been so special. This little device uses light, sound, and vibrational therapy to support natural energetic balance, and I can honestly say we’ve felt that harmony show up in her every day. Amelia is usually very reserved and shy… but since wearing her ONE device, she’s been giggly, happy, and noticeably more confident. Her energy feels lighter. She smiles more. She interacts more easily. There’s a softness and joy coming through that feels like her true self finally shining without blocks. What I love most is how effortless it is — she simply wears it, and it does its work gently in the background, like a constant energetic hug. The fact that it’s patent-pending and created with so much intention and love makes it even more meaningful to us. For our family — especially knowing Amelia’s sensitive nervous system and the deeper layers of her Lyme journey — this device has been a beautiful, supportive addition. If you’re someone who believes in frequency, resonance, and helping the body remember its natural balance, the ONE device is truly worth experiencing. We absolutely love it.

I ordered a necklace for my dad and then discovered it wasn’t appropriate for him to wear. I reached out to customer service to request a cancellation of the item and Mary promptly replied to me, giving me the option of keeping and trying it or cancelling and refunding my money. At this time I felt it appropriate to cancel and she swiftly cancelled the order and refunded my money. I am SO impressed with the customer service that I know I will re-order when the time is right. I love the concept and feel it’s a wonderful product and the customer service is amazing.

It is as if someone replugged the connection between my body and my mind. If stillness had a frequency, it would make such a soothing sound as produced by this machine. You just start feeling yourself again… on your own wavelength.

I love my OneDevice and have been wearing it daily for about 6 months. It gives me a sense of calm and I can tell if I'm not wearing it. Charge lasts a long time and it does not take long to fully charge. I'm just now learning to change the frequency mode. Customer service has been great to work with when I had an issue with the leather cord. Highly recommend. Quality item!!

What a beautiful necklace! I’ve worn The One Device necklace daily, and I can genuinely feel the frequency shift in my body. The gold and copper design is both beautiful and functional—copper being a powerful conductor that supports inflammation reduction and energy flow. I love that I can actually hear the subtle hum of the frequencies, like a quiet guardian recalibrating my field. It’s well-made, comfortably weighted, and unlike anything I’ve worn before—this isn’t just jewelry, it’s a tool for healing. Dr. Pestova

I can tell a difference when I’m wearing it or not wearing it. I feel so much more grounded, calm and loving when I wear it and it goes with everything! Great for sleep aid as well. Highly recommend!
