OneDevice Reviews 45

Delivery took long, didnt come with the chain I ordered, the cheap black cord it came with broke the first time i took it off. Its overpriced for the quality of it 100%. I wouldnt recommend im shocked its a 4.2 rating actually 🙄 i feel i wasted my money

Ordering was easy, great communication. I love wearing my OneDevice - can’t put my finger on why, exactly, but I just feel better when I wear it and miss it when I don’t

0 customer service. Been on live chat for days 0 reply and no reply to emails either.

Update: still no reply to my email days later.

I’m not sure what happened since I bought mine about 3 weeks ago but things change fast. The two reviews below mine couldn’t be any more different than my experience. I haven’t had to email anyone at the company. And over all One which is difficult company to research in regards to ethics and inception but I digress, the emails and responses I do see do seem somewhat generated but that’s life.

I’ll spare a long breakdown by stating I work in an ICU and I have a high stress lifestyle with mental ND’s and sensory issues often related to electricity and energy. Always have. I meditate binaural and infrared/ NIR. I’ve done my own research over years and this device has directly enhanced my experience. With this device I have had the most mental clarity and even though ethical times seem uncertain, I feel the most uninterrupted peace in my stream of consciousness. My meditations have enhanced to higher dimensions with this device on but pls keep in mind I’m ND and have been doing meditation/ astral projections for years. I believe having the One device on and close to my heart is very key.

One thing I did have to add was my own silicone usb stopper that adheres to the back. It did blow my mind a that something this expensive and meant to be worn so often didn’t come installed with one but whatever. It was $5 and held on to the platinum well. Overall it charges well, lasts a very long time. Mine CERTAINLY does emit frequencies and lights and I’ve had no regrets. The cool kids tin foil hat for sure.

Hope to find more information in near future on the owners/ investors of the company and the true ethical principals they stand on. I did see a very lovely yaght photo on ig tho so we’ll see :)

Arrived and does not work. No response from support at The One Device, despite now sending three emails and a "90 day guarantee". Very disappointing. Would not recommend.

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.

This was my first week of trying it.... needless to say atp I barely take it off except for bathing and and workouts. Going thru a divorce shattered my nervous system and this little bit of magic helped to get me back on track.
I love the service support and the communication between them and their customers. I've even spoke with the CEO of the company many times. I would highly recommend.

"A month with The One has completely transformed my daily practice. As a healthcare provider, the immediate sense of calm and spiritual alignment I feel when wearing this medallion is a game-changer. It helps me protect my energy so I can focus on what matters most: healing. Highly recommended for anyone in the caregiving space!"

I got my device on the 23rd of February this year, and the first feeling I got when I wore it was this sense of calm and I felt the noise in my mind just came quietly down, I could feel a lot calmer, three days in and I was sleeping really fine, waking up earlier than I normally do and it has been consistently so up until now,… 7 days in and my confidence is through the roof, I normally would not confront people but recently i have been all out and doing confident shi… this device is a beast when it comes to battery life too, I used it for about 80 hours, yes I calculated every hour, didn’t even turn it off at all at night when I went to bed.. and after 80 hours I just felt I needed to charge it but it was still on and working… then who has dropped theirs by mistake? Me… it had a hard fall on my tile floor and it was still working perfectly even without a scratch… that’s by the way though, the best thing about this device is the new energy you build with everyday use, I suggest using for about 7 days to really notice the shift… this device is powerful to say the least… still on this journey and it’s becoming more and more interesting as the days progress… I am going to have a meditation session with mind and see the difference… more feedback soon.

Surprisingly Tough – Even After a Car Accident!

I got the One Device and right away I felt this gentle, subtle hum—like something quiet inside me woke up. I'm sensitive to sounds, so I could hear it even if it was faint. At first, it took a little focus to notice… however, wearing it for just half a day, the accident happened—I dropped it getting out of the car, and another car rolled right over it.
Thought it was done for. But wow—it kept going! I wore it for a few hours each day over the next few days, same soft hum, same colors spinning. And that resonance, it started feeling more alive, more present—like I could finally hear it without trying too hard or it pulling me away from anything else. That really blew me away.

After that, the battery finally went out. But I am glad that it let me explore this gentle hum I never knew I could feel.

The team was amazing—they sorted everything out super quick, no fuss. I'm grateful.

(5 stars—because it lasted way longer than I expected even ran over by car)

So I receive my one device on Friday immediately upon unpackaging it and putting it on I could feel a sense of calm and warmth wrapping me it was almost like I could feel a buzz but it was absolutely fantastic I haven't taken it off since then except the charge it it hangs over my bed at night and I don't know if it's just me but I slept from the time I put my head on the pillow until my alarm went off in the morning with no interruptions that is completely new for me I can't say enough good things about the one device and what the company is doing Thanks again for all your hard work and for making a fantastic and easy to wear device

After reading the reviews and having used several energy wellness devices and taken supplements, I am somewhat disappointed by the hype. I was really looking forward to a subtle difference, yet I drew a blank. If i leave the device on and sleep with it, it actually impairs my sleep pattern... My 2-year-old daughter is fascinated by the light changing colour and calling them out as they switch... I was hoping for something more, given the reviews and testimonials. Whether I would buy another ? No... Recommend? No.... It is overpriced for what it is---. Yet I will give it a full month before making a final decision and will update the review should I notice a subtle change. Even the powerbalance bracelet had more of an impact on my yoga practise than the ONE device... Its a shame as I was super eager and excited...

Upon receiving my platinum device, I immediately commenced its use to assess its functionality. While some users have reported a vibrating sensation and an audible hum, my unit operates silently, exhibiting only flashing green, blue, and red lights. Consequently, I am concerned about its operational status. Given the price point of this device, I anticipate it to be fully functional. Should it not be, I would like to inquire about the possibility of a refund.

I been wearing it two days. It didn't come with instructions. I charged it put it on. I hear nothing,feel no vibration,and have no idea what the red,yellow or green dots mean. I tried looking up info. Lots of talk but no answer to anything on how I know it's working. Disappointed. I email customer service. Nothing no answer. Am clueless as to if it's even on

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.

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!

tried it for 2 weeks didnt feel any change

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.
