Can’t switch off?15 minutes changes everything.

The DMSPS algorithm introduces a calibrated phase misalignment between the right and left earphone, generating dynamic, multi-layered binaural beats. These guide your brain towards the desired frequencies. You put on headphones, press play, and listen for 15 minutes. The technology does the rest.

Most users report effects from the very first session. The INSOMNIA program lasts about 15 minutes and many fall asleep before it ends. No practice or consistency required — it works every time you use it.

Music. The DMSPS algorithm is embedded in seemingly ordinary tracks — split between classical and modern — composed and produced by Alessio Chelucci and Maria Luisa Mannarino. No white noise, no artificial tones: listening is genuinely pleasant. Pick a track from the program you need, put on your headphones and press play — the technology does the rest.

That’s normal — and it’s the sign that the experience is personalised. We’re all different: the algorithm is the same in every track, but it’s distributed differently in each one, precisely to maximise compatibility across different people. Take a little time and explore the tracks in your program: when you find yours, you’ll know — and from then on, they become your go-to.

With one click from your account — no need to contact anyone. For the monthly plan, you can request a refund within 12 days of renewal if you haven’t used the app. Full details in our Terms and Conditions. Our refund rate is 0.4% — try it once, you’ll stay.

Yes. The annual plan includes up to 10 accounts, the monthly up to 5. You can share it with family, friends or colleagues. Each person gets their own separate account.

Important: sharing is available only when purchasing from the website (effettoviola.eu), not through the iOS or Android app. Apple and Google do not technically allow multi-account subscriptions through their stores: anyone who buys through the app gets an individual, non-shareable subscription.

No, any stereo headphones will work. Even your phone earbuds. The only requirement is that they’re stereo (separate right and left earphones) because the technology works on the difference between the two channels.

Yes! Effetto Viola has been a Trenitalia partner for five consecutive years. You can use it for free on board Frecciarossa and Frecciargento trains via the FRECCIAPlay portal. CartaFRECCIA holders also get 50% off the subscription.

You always use Effetto Viola through the app (iOS and Android) and the price is identical. The difference lies in the benefits.

Buying here on the website: you can share the subscription with family or colleagues (up to 5 or 10 accounts), you get refund protection within 12 days, and you can request an invoice.

Buying through the app (Google/Apple): access is limited to a single device, no refund is available, and invoices cannot be issued.

Yes, and plenty of it. EffettoVIOLA counts a significant number of healthcare professionals among its users — psychologists, psychiatrists and psychotherapists who use it before sessions to help patients reach a state of relaxation prior to the consultation, making them more receptive and easier to treat.

It is also used in structured clinical settings — hospitals and private clinics — with the specific aim of reducing pre-operative physiological anxiety, replacing or reducing the use of anti-anxiety medication.

For those who want to dig deeper, we have prepared a dedicated page with the complete collection of peer-reviewed scientific literature on Binaural Beats, the meta-analysis of 22 international studies, an explanation of the proprietary DMSPS algorithm, and the data on inter-hemispheric coherence measured after use.
