This page sets out the regulatory status, safety conditions and limits of liability you should know before using REZZONIX products. Please read it before use.

Regulatory status

REZZONIX products are developed for professional and research use. They have not been approved as medical devices by any health authority, and no such approval has been sought.

Do not use REZZONIX products in place of prescribed medication, treatment recommended by your doctor, or emergency medical care. If you have a health concern, see your doctor.

No guaranteed outcome

We give no warranty that the products will produce any particular outcome for any individual. Personal experience is not evidence, and no user account is presented by us as a claim of efficacy.

When to consult a doctor first

Always consult your doctor before using REZZONIX products if any of the following apply:

You have a pacemaker, defibrillator or any other implanted electronic device
Epilepsy or a history of seizures
A hearing condition
Pregnancy

Use is not recommended with small children. If it feels uncomfortable, stop.

Safety warnings

When using headphones, high volume levels are a hearing risk — keep the level low. Use the application modules (Helmet, Glasses, Wristband) only by connecting them to the main REZZONIX device and following the instructions supplied with the product. Do not use with a damaged cable or body.

The catalog in the mobile app

The frequency catalog in the app came out of the personal study of our founder and researcher Yakup Öner. That work has not been independently verified or peer-reviewed. We present the catalog as the organised form of our own research, not as a claim of accuracy.

Use around animals

Many animals hear far wider ranges than humans (dogs ~45 kHz, cats ~64 kHz). A tone inaudible to you may be distressing to them. Watch the animal's reaction and stop if you see discomfort. Consult a veterinarian for any concern about your animal's health.
