Arrived yesterday, and I am very impressed so far. My stress levels are way down already. It’s magical. If you are prone to stress or reactivity, you may notice less of that. But you don’t actually feel anything physical from the device. Just more calm.

I am thrilled to say that I have ordered a second device to fill the gap when the other one is charging. Since I have been wearing the One Device, I am migraine-free, and I almost sleep like a baby. It exceeds all my expectations!

What a beautiful necklace! I’ve worn The One Device necklace daily, and I can genuinely feel the frequency shift in my body. 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.

As a Sound Healing Practitioner and Fitness Professional, I was very curious about this. I’ve been wearing The One Device for about two weeks now, and I can genuinely feel a difference. I feel more grounded and focused throughout the day, with noticeably less irritability and anxiety at work. I have a very high-pressure, demanding job, and this has helped me feel more regulated and steady instead of constantly running in overdrive. I also really love the weight and feel of it against my skin, it’s comforting and grounding without being distracting. Overall, it feels like it’s helping my nervous system stay in better balance. Subtle but meaningful support that I didn’t realize I needed until I felt the difference.

I've been using The One for a few weeks now, and it's quickly become part of my daily routine. The combination of light, sound, and vibration therapy is unlike anything I’ve tried—it feels like a full-body reset in just minutes. I’ve noticed deeper sleep, better focus during the day, and a subtle but steady sense of calm. If you’re into biohacking or just want to feel more balanced and energized, The One is absolutely worth trying.

I rarely leave reviews, but this device is worth mentioning. As someone navigating chronic fatigue, this has bencome part of my daily wellness stack. Sleek, easy to use and no nonsense. It's subtle but powerful. Highly recommend if you're looking for something beyond supplements.

OMG I LOVE IT SO much already. It is sooo coherence creating I feel the vibrations mesh with my body.

I can’t leave my house without it. I can REALLY feel myself more connected with everything including my own body. As a trainer and nutritionist I’m happy to have meet your amazing device. A perfect tool to integrate my body/ mind and energy ✨🙏🏽

I love mine got one for Christmas to be honest. I wasn’t sure anything was really working first couple of weeks but I stuck with it and what I noticed is actually I noticed it more when I wasn’t wearing it so it definitely does calm the nervous system down. 🥰

Three days in and I’m seeing subtle yet powerful shifts. I stopped grinding my teeth. I stopped having nightmares. And I wake up more alert, ready to take on the day. Nice start!

I have been wearing mine for a few months now. I can't express in words the depth of the changes that The One has made for my entire being and my quality of life. I am so much calmer overall and my body is settling down into peace and harmony. There is no doubt in mind that this device has helped my body to be relieved from so many random and unexplainable symptoms. I know I cannot prove this emphatically to be able to give absolute credit to this modality of healing support, but as having suffered from so many physical and emotional distresses for most of my life.... my experience has been life changing since I began wearing it and without making any other appreciable changes. For One, I am grateful!

My experience so far with The OneDevice is nothing short of spectactular. First, it feels similar to tuning forks I have so I know it's working. For best results I wear it under my clothes in direct contact with my body and I can feel subtle pressure in my head/crown chakra with certain frequencies more than others. Second, what it seems to be doing over the first couple weeks is giving me a subtle yet profound sense of personal empowerment. I am feeling more empowered over my mind and body so that I am now calling the shots instead of living as a victim to addictions and cravings, for example. I haven't felt this in my entire life and i'm in my mid 40's. It's assisting in helping my True Self take full control of my life, which is priceless if you think about it. Edit: After writing my review, I read all of the others. There is a common theme: Subtle & Profound

Joe P.

This is the most incredible frequency device! As a holistic health care practitioner, I use frequency daily, and the fact that they have created a wearable frequency device that looks beautiful blows my mind. It auto-adjusts to the frequency my body needs in the moment, but I can change it if I want to lock in focus at work, or wind down for sleep, etc. I won’t take it off!

Brit G.

Day 1-2 using one device improved sleep 1st and 2nd day. Been focusing on blue, red, quartz and violet for now. Sleep setting seems to have an effect. Too soon to confirm but def took notice on sleep. Day 3-4 ok.... getting clearer effects experienced waves of emotion during internal reflecting noticeable when at a restaurant my vibes were buzzing engagements were consistent almost magnetic. Overwhelming confidence and sense of peace during the night out. Worth noting the week of purchase I was 6 weeks in working out 5 times weekly eating clean juicing and taking natural supplements (chlorella, zinc tumeric etc). I think this helps but I've been more focused on sticking to goals (didn't cheat or have the urge to for cheat meal during a night out bday party). Strong sense of wanting to get goals done. Honestly starting to believe the effects. Day 5-6 atp I am certain I'm feeling effects. Richer and deeper sleep with more vivid dreams, usually a light dreamer as i got older. My vibe just feels amped for a lack of better words. Feeling locked in on my workouts, fitness and health. Like a charged optimism. Still not even a full week in so I still need more time but im logging this day-by-day as a real non bias customer who was very much skeptical initially yet starting to feel less so. Let's see where this goes and I will continue to post my experiences.

Thank you very much and the other day I woke up feeling so great aligned and I’m at a peaceful feeling up-to-date. Really nice device incredible ❤️😎💯✅

Enrique R.

It's hard to put into words what the first 2 weeks of wearing The One Device is doing to me. It's subtle but very powerful. I feel like, for the first time in my life, that I am taking control of my mind, thoughts, and actions at a deep core level. It's like, instead of having things like addictions/cravings rule me, I now feel as if I am rising above such things and am having a much easier time abstaining from things that are detrimental to my health and wellness.

Joe P.

United States

I have had mine for about 10 days and wear it everyday and hang it by my pillow at night. I felt the effects around the second day, and it continues to improve each day. I have tried so many modalities to try to give me relief from my neuro-divergent brain and a myriad of physical symptoms from nervous system disorder that I have suffered all of my life; I am now 67. I can speak with great confidence that it working for me without a doubt. My energy level is up, my mind is more settled, with less emotional upset and anxiety, with seemingly feeling normal physical responses to stimuli. I know that as this works on a synergistic level and, therefore, will be a personal experience as to effectiveness, I believe it can be amazing for many who have challenging nervous system disorders. I never want to be without this device and am so grateful to have The One!

I got mine today. What I feel is more integrated, something I cannot really explain. Stronger.

Nissim M.

So far I love it! I got it as a gift from my girlfriend and i wasn't really sure about it. But I'm glad I actually used it. I've been wearing it every day now for about 3-4 weeks and it has definitely made a difference in my sleep. I feel more restful in the morning and it's been easy to get up and go. I've also felt a lot more grounded lately.

Francisco B.

United States

It’s not only how you feel ✨❤️. I’ve been using it for about six months, and it’s the synchronicity that starts happening in your life. How you meet amazing new people, how doors and opportunities open up, and how you vibrate and allow yourself to see the world from different perspectives. All thanks to staying aligned with a frequency that’s more in tune with our spirit and our true essence.

David T.

United States

Hi I received the pendant today and not only is it beautiful but the energy is amazing! I felt it in my heart chakra almost immediately and now it is going up and down my body, it's like a warm hug. My puppy keeps checking it out. I look forward to eventually getting my personal frequency. Thank you so much.

Brenda P.

Yep had mine 3 days ago a feeling like I’m now in my body for first time in years.

Thomas P.

United Kingdom

I am having a profound Kundalini awakening. I usually have them at night frequently, and they become very violent but subside when I fall asleep. They occasionally occur during the day in deeper states of meditation. As soon as I put on The One, I felt the vibrations. My ajna chakra became more vibrant, and when I fell asleep, I saw much more vividly and was able to remember my dreams much more clearly. When I woke up, I felt an almost metallic taste in my mouth that hasn't left. It's like tasting batteries. Then, before I went to sleep for a nap today, I felt my root chakra open and a current of kundalini flow that has not stopped. I feel pure bliss, pure ecstasy. I have had energy openings before, but they were usually impermanent, save a few. This is a profound inner shift. I am sure my kundalini will permanently activate now throughout the day and night. My etheric body is glowing bright, and I can feel its light.

Christopher D.

Thank you, The One Device team. My order has arrived, and I am truly fascinated by the device. Within just five minutes of wearing it, I felt a deep sense of calm and balance come over me. It harmonized me instantly and gently brought me fully into the present moment. I am already recommending the device to all members of my family, as the experience has been truly impressive. Thank you for the amazing work you are doing. Please keep it up.

Simion A.

I've been using The One for a few months now. It's a decent product. It feels high quality, and the design is nice. As for the effects, they're kind of hit or miss for me. Some days I think it helps me focus, other days I don't notice much difference. For the price, I was expecting something more obvious. Not sure I'd recommend it, but I'm still hopeful it'll kick in more over time.

I've been dealing with chronic stress and it's had a big toll on my body, mind and overall health. But using the one has helped reduce the constant stress and has made me feel more relaxed and at ease. I love that it has a combination of sound, light and vibration therapies.

Kay

This device is my best friend!!! I don’t understand the technology and how it works exactly, and honestly I don’t care that much. I have ADHD and I used to get easily distracted and lazy. My life has completely changed since I wore ONE. I don’t know what happened, but I have been wearing ONE for 2 months and I feel way more focused and clear. I stopped procrastinating and I have a different drive and motivation towards my goals and my vision. Not sure why and how, but ONE definitely works!!! Thank you ONE team, endless gratitude to you!!

Jackie L.

I’ve had the One Necklace device for about two weeks now, and I can confidently say I’m really happy with my purchase so far. Everything works exactly as described—no flaws, glitches, or issues to report. The black nickel color I chose looks amazing in person—sleek, modern, and super stylish without being too flashy. It gives off a nice premium feel and goes well with just about anything I wear. I also have to give major credit to the company behind it—they were extremely responsive and professional throughout the entire process, from ordering to delivery. It’s rare to find both a well-made product and great customer service these days, but this hit both marks. Definitely recommend if you’re thinking about picking one up.

Kellen N.

United States

I have been getting up every morning for 3 years with strong inner restlessness and since then I have not been able to breathe properly. The unrest often follows me throughout the day and due to the shortness of breath, every day is a struggle. After a few panic attacks and countless anxiety attacks, I am now addicted to prescription tranquilizers. Since wearing The One Device I am breathing and have no agitation at all throughout the day. I even forget to take my meds. It's an incredible feeling.

Alma S.

Germany

I've been on a long journey with my health--burnout, anxiety, sleep issues, you name it. I came across The One Device during a late-night scroll and something about it just felt right. I've now been using it for a little over a month, and it's hard to put into words how much lighter I feel. It's not like a sudden jolt of energy or some dramatic change--it's gentle. Like your nervous system just finally gets to exhale. I use it in the mornings before journaling and again in the evening when I'm winding down. It's become part of my daily rituals, and I honestly can't imagine not having it now. I've recommended it to a few friends who also deal with emotional overwhelm or scattered thoughts, and they've had similar responses. It's subtle but profound. Grateful this exists.

Olivia C.

United States

I travel a lot for work and I am constantly looking for things to help me stay grounded. meditations apps, breathing exercises, you name it. I bought the One not really knowing what to expect. Six weeks in, I fell steadier, My sleep is better, and I don't feel as drained after flights, I'd love if they share more info about where the crystals come from, but overall, I am happy with it.

Bounce P.

As much as I was impressed and motivated after reading about the One Device, I nevertheless tempered my expectations. After I began wearing it, I consistently experienced both subtle and enhanced energetic shifts. My body, mind and sprit welcome it.

Richard L.

United States

Ok so I wasn’t totally sure about this thing at first, but I’m 3 weeks in and it’s working. I don’t feel as drained after work and my sleep is much better. I actually feel rested in the morning.

Zac R.

United States

At first, I assumed it was another trending wellness gadget that most people get roped into. I wasn't convinced. After a month of wearing it, I started noticing minor changes such as: less brain fog, less stress towards the end of the day. Its not like my life is drastically changed, but I do feel a more sense of unshakable balance. I like that its not a bulky device. It's simple, clean, but most of all subtle.

Kent C.

I had no clue what I was getting into but its been awesome! Thought it was just gonna be a gimmick but I actually feel calmer?? hard to explain. I am super sensitive to vibes and this helps me stay centered, also obsessed with the copper.

As a meditation enthusiast, I'm always exploring tools to deepen my practice. The One Device seamlessly integrates into my sessions, enhancing focus and promoting a deeper state of mindfulness. Its gentle cues guide me into a tranquil space, making each meditation more profound.

Angel

United States

My friend told me about "the one", and honestly... I laughed. I thought, no way am I buying jewelry to help fix my energy. But here I am, two months later, wearing it every day. I work in IT, so there's tons of screen time, and I usually feel drained by 3pm. This thing gives me a weirdly steady energy that avoids the afternoon crash.

Zierra W.

United States

The one has definitely helped me so much during my times of meditation,I have felt a difference hence I started using it, I feel more grounded and just so at peace. Even when I’m not meditating I still wear mine. I just feel a difference in the way I feel so it has become a must for me, to wear almost daily. I am so grateful to have found this device it truly has been a game changer, I now cannot be without it.

Erika M.

When I wore the One, I felt a huge heart opening and an instant connection to Source. I compare this experience to NSA (network spinal analysis). There was a feeling of harmony, peace and at the same time great amount of energy was running through me.

Luba F.

United States

When my husband first purchased his OneDevice, I was a bit of a skeptic. I tried it on for the first time and did not feel a thing. He, however, swore he could feel something. I gave it a chance and would put it on occasionally when he was unable to wear it. Slowly over time I found myself wearing it more and more to the point where I was requesting to wear it when I had a big meeting at work. He surprised me with one for my birthday and I promise you it has been a game changer. When I am not wearing it around my neck during the day, it is hanging by my bedside while I sleep. It is hard to explain, but just buy one already.

Amanda B.

United States

I've tried a bunch of wellness devices before, some have helped and some were a total waste. What I like about one is the combination of light sound and vibration in something wearable. Most things I've used are clunky or you have to sit still to use them. I travel a lot for work and needed something portable. I have been using it for about six weeks and feel more balanced overall. My HRV scores are better too.

Andrea R.

Ever since I came across ONE website I have felt a deep sense of resonance. I immediately knew i was not there by accident,l believe the device was calling me and i was guided there. I purchased it immediately. Since the moment I started to wear it I have been receiving constant downloads and intuitions, I feel my heart wide open and crazy synchronicities are happening to me on a daily basis. I have been wearing ONE for 3 months now and I have a highly paid brand new job, a new partner whom I am madly in love with and my sleep has improved by 100 times!! ONE is now my to-go-gift and if you are now reading this review... maybe it's because ONE is calling you too! Thank you so much ONE.

Lucas F.

Costa Rica

I was a bit skeptical at first. I decided to buy it just because it was a beautiful piece of jewelry and way more affordable than many of the stuff out there! Once I wore it I almost immediately felt a deep state of Centeredness and peace. I have been wearing it for more than a month and I can feel the difference in my body and my overall mental state when I don't wear it. I never take it out! Definitely a must have!

Inna S. 

United States

Let me first tell you how wonderful your product has been for my son. He has always had difficulty with his emotions & temper. He loves “The One”! His girlfriend even notices a difference in his essence & being. She has said to him, “go get your ONE & get yourself centered”. It’s amazing!

Cecilia B.

United States

I really love this device. First time in years that I have slept almost all night without getting up, three nights in a row, to use the bathroom. Is it a placebo? Maybe, but I really don’t care. I’m wearing it full time. I plan on wearing it full time for a week and then not wearing it to bed to see if there’s a difference.

Janelle

I became intrigued after hearing your appearance on Sean McCormick's Optimal Performance podcast. When | later saw Sean wearing it, I reached out to ask how he liked it. His response was simple: "Get it." l'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.
