Harmoniq is a wearable wellness device — the Limitless Neckband — that uses patented ulRFE® (ultra-low radio frequency energy) technology to help you shift your mental and physical state, without any drugs or supplements. The Neckband emits ultra-low radio frequency energy signals called Frequencies (such as Zen Companion, Deep Work, and Creative Boost) that your body interprets to help you boost energy, sharpen focus, or ease into deep rest — all at the press of a button. Wear it, choose a Frequency, and let the science do the work.
Using the Limitless Neckband is straightforward:
Wear the Neckband comfortably around your neck.
Open the Harmoniq App on your iOS or Android smartphone.
Select a Frequency for the state you want — for example, Deep Work for focus or Zen Companion for calm.
Choose your session duration and let the Neckband do the rest.
No ingesting anything. No complicated setup. Just wear it and feel the difference.
Tip: Make sure your Neckband is charged and Bluetooth-connected to the app. The app will guide you through pairing on first use.
Yes. The Limitless Neckband is designed with safety as a priority. It uses ultra-low radio frequency energy — far weaker than the signals emitted by a typical cell phone. All Frequencies undergo rigorous safety and efficacy testing before release. There are no chemicals or drugs involved, just low-energy signals operating at levels well below those of common electronic devices, making it a non-invasive wellness tool.
The Limitless Neckband is intended for adult use only. We do not recommend using the Neckband if you are under 18 years old, if you are pregnant, or if you have a medical implant (such as a pacemaker). These precautions exist out of an abundance of caution — the effects of the Neckband's signals have not been fully established for those groups.
If you have a serious medical condition (such as epilepsy or a seizure disorder) or any implanted electronic device, please consult your doctor before use. When in doubt, reach out to our support team or your physician to confirm the Limitless Neckband is right for you.
The Neckband is fine for lighter activity, but we do not recommend using it during high-intensity exercise that causes excessive sweating, as moisture can affect device performance over time if it enters the hardware. We also advise against wearing it during high-intensity sports or labor-intensive environments where the device could get caught or pose a safety risk. Your safety is our top priority.
Yes — many users do. If you find wearing it around your neck less comfortable during sleep, try placing it under your pillow. The Neckband is designed to emit its signal within a range above and below the device, so you'll still benefit from the Frequency as long as the Neckband is nearby.
No. Do not wear the Limitless Neckband in water. Exposure to water (shower, pool, rain, etc.) may damage the device.
No. The Neckband emits a completely silent signal. You may notice a small vibration when you connect the device or when a session starts and ends — that's it.
No — one subscription covers multiple Neckbands. However, two devices cannot be played simultaneously on the same subscription.
No. The Harmoniq App is required to operate the Limitless Neckband. Download it from the Apple App Store or Google Play Store and create your account to get started.
Most people notice the effects of a Frequency within minutes. Users commonly report a shift in mood or state — feeling calmer, more focused, or ready for sleep — shortly after starting a session. That said, individual responses vary. Some feel it almost immediately; others may need a session or two to tune in.
The effects are intentionally gentle, so pay attention to subtle changes. If you're not noticing much at first:
Try a longer session.
Try a different Frequency.
Make sure your environment supports the state you're aiming for (for example, use a sleep Frequency when you're settled and winding down, not mid-activity).
Most users find their rhythm within the first few sessions. Rediscover your flow — it's closer than you think.
The Limitless Neckband is a one-time purchase priced at $399 USD, backed by a 45-Day Money-Back Guarantee. If you're not satisfied within 45 days of receiving your device, you can return it for a full refund — so you can explore with confidence.
Visit feelharmoniq.com for the most current pricing and any available offers.
A membership unlocks the full library of Frequencies in the Harmoniq App. There are two plans:
Plan Monthly Yearly Includes Sleep / Calm (Strain Relief) $10/mo $99/yr Sleep and Calm frequencies and experiences All Access $19/mo $199/yr Every frequency and experience in the library
Every membership includes a 30-day free trial. Your trial begins when you set up your membership in the Harmoniq App after your device arrives — not at the time of purchase — so shipping time never eats into your free period. Cancel before day 30 and you won't be charged a thing.
Memberships are flexible and cancellable — you're never locked in long-term.
If you choose not to continue your membership after the free trial, your Limitless Neckband will have limited functionality. You'll retain access to only a small selection of Frequencies, rather than the full library. To unlock all Frequencies — including new additions over time — an active membership is required.
Think of it like a music streaming service: without a subscription, you get a single station; members get the entire catalog. You can always subscribe later if you initially opt out.
Harmoniq occasionally runs promotions and limited-time offers. Rather than list anything here that may have changed, check feelharmoniq.com for whatever is currently available. Choosing an annual membership plan is always a straightforward way to save compared to paying month to month.
And remember: the 45-Day Money-Back Guarantee on the Limitless Neckband means your initial purchase is effectively risk-free. If the Neckband isn't right for you, return it within 45 days for a full refund.
Here's exactly how it works:
Purchase the Limitless Neckband at feelharmoniq.com.
Your device arrives in a few days.
Download the Harmoniq App and go through the sign-up/payment portal to create your account.
Set up your membership in the app — this is when your 30-day free trial begins. Not at purchase. Not at shipping. At activation.
Log in to the app using the account you just created. That account's email is your subscription email and your login email — they are automatically the same.
Important: The email you used to buy the Neckband on the website does not need to match your app/subscription account. The account that matters is the one you create when setting up your membership in the app. If you ever have trouble accessing your subscription, make sure you're logged in with that membership account.
