Other Brainwave Entrainment Devices

The DAVID Delight Plus is the most popular model in the Delight family: 28 built-in sessions, five in every category, plus three gamma sessions the base Delight does not have. No app, no subscription, nothing to program.

Made by Mind Alive Inc. in Edmonton, Canada, the Plus is designed for people who want real choice in their routine. Different depths, different lengths, different approaches to the same goal, so the session that fits a rough Tuesday is there when you need it.

Designed to support

• Stress regulation and a calmer baseline over weeks of regular use
• Easier sleep onset and staying asleep
• Focus, attention, and mental clarity
• Mood support and emotional balance
• Energy in the morning without caffeine

28 built-in sessions

About the gamma sessions

Gamma activity around 40 Hz is associated with higher-level processing and sharp attention. The Plus includes three ways to work with it: a session that cycles between 40 Hz and the calming SMR range (12 to 15 Hz), a randomized session that varies around 38 to 42 Hz, and a fixed 40 Hz session. Gamma stimulation is an active area of research; we describe it as a focus tool, not a treatment.

How it works

Audio-Visual Entrainment (AVE) delivers gentle pulses of light through the eyeset and matching tones through the headphones. The brain tends to fall into step with a steady rhythm, a response called frequency following, which researchers can observe on EEG within a few minutes. Each session is built around a target range: faster rhythms for alertness, slower rhythms for relaxation and sleep. Sessions end with a gradual soft-off fade so you are not startled.

AVE has been studied for more than 30 years. Published work includes shorter sleep onset in older adults using evening sessions, improved seasonal mood scores with morning sessions, attention gains in students, and mood and balance improvements in seniors. Mind Alive's own pilot studies are small (6 to 8 participants) and are described as such on their research pages. We share this so you can weigh the evidence for yourself.

Technology

• Tru-Vu Omniscreen eyeset. Eight blue-tinted white LEDs behind a translucent screen spread light evenly across both eyes and can drive each side at a different rate.
• Randomized stimulation. Small variations within each session help the brain follow the rhythm without habituating to it.
• Night-Vue buttons. Raised, illuminated controls you can find in the dark without opening your eyes.
• Soft-off fade. Light and sound dim gradually at the end of every session.
• Portable power. Runs on the included 9-volt battery or the AC adapter.

Choose your eyeset

• Standard (white) eyeset, eyes closed. Soft white light seen through closed eyelids as shifting patterns. A clean, neutral choice for calm, focus, and sleep.
• Multi-Color eyeset, eyes closed. Adds color to each session: blue for calm and sleep, green for meditation, yellow for focus, red for energy.

Which DAVID is right for you?

The Delight has 10 sessions and is the easiest place to start. The Delight Plus has 28 sessions including gamma. The Delight Pro has the same 28 sessions and adds Cranio-Electro Stimulation (CES). The Premier is the programmable, practitioner-level model with the full-color Spectrum eyeset.

DAVID devices are not intended to diagnose, treat, cure, or prevent any disease. They are designed to be used alongside, never instead of, any care you already have. Individual experiences vary.

The DAVID Delight is the simplest way into Audio-Visual Entrainment. Ten built-in sessions, no app, no subscription, nothing to program. Choose a session, put on the eyeset and headphones, and give yourself twenty minutes.

Made by Mind Alive Inc. in Edmonton, Canada, the Delight is designed to support calm, focus, and sleep with light and sound rather than pills. It is the model we recommend for first-time users and for anyone who wants a routine that fits in a bag.

Designed to support

• A calmer, quieter mind after a stressful day
• Easier sleep onset and a steadier evening wind-down
• Focus and mental clarity during work or study
• A brighter mood, including through the darker months
• A caffeine-free lift in the morning

10 built-in sessions

Two sessions in each of five categories, so you can pick by need.
