Questions, answered.

AVE delivers synchronized pulses of light through LED glasses and matching tones through headphones at specific frequencies. Your brain naturally follows along — the frequency-following response — which can guide it toward states associated with calm, focus, energy or sleep. It is drug-free and built on 40+ years of research.

CES uses a gentle micro-current delivered through ear-clip electrodes to support the nervous system. It is often combined with AVE for calm, sleep and stress protocols. CES is included on the Delight Pro and Premier (the Delight and Delight Plus are AVE only).

AVE works through light and sound; CES works through a gentle micro-current via ear-clips. Every DAVID includes AVE; the Pro and Premier add CES, and you can use them on their own or together.

No. Every DAVID runs its built-in sessions on its own — no computer, phone or subscription. The Premier can also be programmed with the DAVID Studio software if you want custom protocols.

Most built-in sessions run 15–45 minutes. Sleep and deep-relaxation sessions are longer; focus and energy sessions are shorter. You can stop at any time.

Most people find a daily session works best. Many run a calming session in the evening and a focus session in the morning. Cumulative effects on your baseline typically build over 3–6 weeks of consistent use.

Many people feel a shift during the first session — usually a deeper calm or sharper focus. Steadier changes in sleep, calm and morning focus often settle in over 2–4 weeks of daily use. Responses vary.

Sessions are tuned to alpha, beta, theta, delta, SMR and gamma ranges — associated with calm, focus, sleep, relaxation and alertness. Each session names its frequency and intended state.

The Delight Plus, Pro and Premier are programmable, and the Premier is fully programmable through DAVID Studio — so you or your practitioner can build custom protocols.

Most people notice something in their first session, though responses vary. AVE and CES are a structured, drug-free support for calm, focus and sleep — used alongside, not instead of, professional care.

AVE and CES are non-invasive and drug-free, and have been used in clinical and home settings since the mid-1980s. Stimulation is gentle and well below thresholds that cause adverse effects. Tens of thousands of units have shipped worldwide with a strong safety record.

Side effects are uncommon and mild — occasionally light-headedness, a mild headache or grogginess if a session runs too long when you are starting out. These usually settle within a session or two; shorten the session or pick a lower frequency if needed.

It is not recommended if you have a history of seizures or photosensitive epilepsy, an implanted electronic device such as a pacemaker or defibrillator, or a cochlear implant. If you are pregnant, recovering from a head injury, or on psychiatric medication, check with your clinician first.

In extremely rare cases, AVE has been associated with seizures in people with photosensitive epilepsy. If you or a family member has any seizure history, do not use DAVID without first consulting a neurologist. The included safety guide covers the warning signs.

It is generally used with children from around age 8, with adult supervision and shorter sessions. Many practitioners run reduced-length sessions for children — we recommend involving a pediatric clinician for ongoing use.

Many people use DAVID alongside therapy or medication as a drug-free support. It is not a substitute for treatment — if you have a medical or psychiatric condition, check with your clinician first.

Relaxation and sleep sessions can leave you deeply calm. Give yourself a few minutes to re-orient before driving or using machinery.

Most people start with the Delight Plus or Delight Pro. The Delight Plus is a strong default for home sleep and calm; choose the Pro or Premier for CES and full programmability or clinical use. Our quiz recommends a match based on your goals.
