The Mind Alive DAVID line is one of the longest-running families of audio-visual entrainment devices. The Delight, Delight Plus, Delight Pro and Premier all use light and sound, but they are not simply four sizes of the same product. They represent a clear ladder: simple AVE, expanded AVE, AVE plus CES, and finally a much more advanced clinical/professional platform with extra stimulation technologies and deeper programmability.
This article gives a detailed practical overview of the DAVID Delight, Delight Plus, Delight Pro and Premier. It explains AVE, CES, MET and optional tDCS in plain language, compares the models, discusses session design philosophy, clarifies where these devices are strong, and places them in context beside Kasina, NeuroVIZR and NeuroSync Pro Audio+Light.

What is DAVID?
DAVID is Mind Alive’s family of audio-visual entrainment devices. AVE uses rhythmic flashing light and pulsing sound to present periodic stimulation to the nervous system. The idea is that carefully chosen frequency patterns can support changes in arousal, attention and subjective state. The user typically wears an eyeset and headphones while selecting a pre-programmed session from the device.
Mind Alive presents the DAVID devices as non-pharmaceutical wellness tools. Their product pages discuss areas such as stress reduction, sleep, mood, mental sharpness and focus. A careful interpretation is important: the device delivers structured sensory stimulation; it does not directly measure brain activity, force the whole brain into one frequency, or replace medical or psychological care.
AVE: the foundation of all four models
Audio-Visual Entrainment is the shared foundation. In DAVID systems, light pulses through an eyeset while sound pulses through headphones. Depending on the session, the stimulation may be alpha-like, theta-like, beta/SMR-like, sleep-oriented, energizing, meditative or gamma-oriented.
The practical appeal is simplicity. A user does not need to create a curve, route DMX, choose a music category or build a timeline. They choose a session category and let the device run. That makes the DAVID line very different from a software system such as NeuroSync Pro Audio+Light, where the professional can design each section of the experience manually.
DAVID Delight
The DAVID Delight is the entry point. Mind Alive describes it as the easiest-to-use and lowest-cost DAVID AVE device, with large session buttons and 10 sessions: two in each of five categories. Those categories are Energize, Meditate, Brain Booster, Sleep and Feeling Better.
The Delight is therefore not trying to be a workstation. Its strength is direct use. It is made for people who want a few well-defined session categories, simple controls and a minimal learning curve. Mind Alive specifically frames the large raised buttons as helpful for users who value simplicity, including seniors.
This model is best understood as a personal AVE appliance. It is not the right choice for someone who wants custom session authoring, CES, external lighting control or deep parameter editing. It is the right choice when the question is: can I choose a simple light-and-sound session without configuring anything complex?
DAVID Delight Plus
The Delight Plus keeps the same general AVE-only identity but adds more session depth. Mind Alive’s current product information describes 28 sessions: five sessions in each of the core categories plus additional gamma sessions in the user-designed area. The company also notes sound-sync sessions and limited user-designed session slots through the DAVID Session Editor, available separately.
The real difference from the Delight is not just quantity. More sessions mean more nuanced pacing options. A user who starts with broad categories may later want different sleep, meditation or brain booster routines. The Delight Plus gives more room without introducing CES or the extra clinical/technical layers of the Pro and Premier models.
For many personal users, this may be the practical sweet spot. It is still a dedicated AVE device, but it has enough variety to feel less limited than the basic Delight.
DAVID Delight Pro
The Delight Pro adds Cranio-Electro Stimulation, commonly abbreviated CES. According to Mind Alive, AVE and CES can be used together or separately. The company describes the CES frequency as linked to the AVE session frequency, with an option for 100 Hz CES.
This is a major change in category. AVE is sensory: light and sound. CES uses a low-level electrical stimulation pathway, typically through earclip-style electrodes. That makes the Delight Pro more interesting for clinicians and advanced users, but also more demanding from a safety and responsibility perspective.
The Delight Pro is therefore not merely “Delight Plus with more sessions.” It is the first model in this comparison that combines sensory entrainment with electrical stimulation. That combination may appeal to practitioners who want more choices in one portable unit. It also means users should pay careful attention to contraindications, device instructions and professional guidance when appropriate.
DAVID Premier
The DAVID Premier is the top model in this group. Mind Alive’s comparison chart calls it the most advanced DAVID brain-machine. The Premier includes Audio-Visual Entrainment, Cranio-Electro Stimulation and Micro-current Electrotherapy using optional electrodes, with optional Transcranial DC Stimulation available at additional cost.
The Premier also changes the user interface. It has a lighted graphic display showing session information and technical parameters, and it reports remaining session time. Mind Alive describes advanced dual-hemisphere AVE, randomized AVE/RAVE, frequency coverage from Infinity Ganzfeld™-style use to gamma, and a Spectrum eyeset supporting a very large colour range.
The Premier is also the most programmable. Mind Alive states that DAVID Studio on Windows can be used to program the Premier and pair sessions with audio files. The company also notes microSD storage, custom sessions and WAV audio support. This makes the Premier much closer to a professional platform than the Delight family.

CES, MET and tDCS: why the Premier and Pro require more care
The moment a device adds CES, MET or tDCS, the conversation changes. Light and sound stimulation are still sensory technologies. Electrical stimulation technologies interact with the body more directly and require stricter attention to instructions, contraindications and user suitability.
CES is typically associated with low-level cranial electrical stimulation. MET is micro-current electrotherapy. tDCS is transcranial direct current stimulation. These terms can sound simple in marketing, but responsible use requires a much more careful mindset than simply pressing play on an audio-light session. People with implanted medical devices, seizure history, neurological conditions, pregnancy, cardiac concerns, medication complexity or psychiatric instability should not improvise with electrical stimulation.
This does not make the Pro or Premier “bad.” It means they are more serious tools. Their added power is exactly why they require more disciplined use.
Eyesets and visual style
Mind Alive sells the Delight-series devices with choices such as white eyesets, viewhole eyesets and multi-colour eyesets. The Premier uses the Spectrum eyeset, which Mind Alive describes as supporting nearly 200,000 colours and calibration for colour-therapy style work. The eyeset choice changes the experience substantially.
A white eyeset is straightforward and rhythm-focused. A multi-colour eyeset adds visual richness. A viewhole eyeset allows some visual openness. The Spectrum eyeset moves further toward a colour-programmable experience. For users comparing this category with Kasina or NeuroVIZR, this is important: DAVID systems are not all visually identical. The model and eyeset combination shapes the session.
DAVID versus Kasina
Kasina and DAVID both belong to the broader light-and-sound mind machine world, but their cultures differ. Kasina is strongly associated with encoded media such as AudioStrobe and SpectraStrobe, built-in playback, microSD media and coloured GanzFrames. DAVID is more associated with pre-programmed AVE categories, clinical-style use, CES options and the Mind Alive research/training ecosystem.
| Aspect | DAVID Delight/Premier line | MindPlace Kasina |
|---|---|---|
| Core identity | AVE devices with a ladder from simple sessions to CES/MET/tDCS-capable systems. | Mind media player with strong encoded light-and-sound media support. |
| Media culture | Pre-programmed sessions and, on higher models, DAVID Studio programming. | AudioStrobe/SpectraStrobe media, MP3/WAV and session playback. |
| Professional angle | Strong in Pro/Premier because of CES and advanced options. | Strong for standalone AVS and encoded media, less clinical-electrical in orientation. |
| Best fit | Users who want structured DAVID sessions or practitioner-oriented stimulation options. | Users who want portable encoded light-and-sound media and rich colour glasses. |
DAVID versus NeuroVIZR
NeuroVIZR is app-led and built around brain engagement language, dynamic light patterns and short guided wellness experiences. DAVID is more button/device-led and rooted in traditional AVE categories. NeuroVIZR feels modern and consumer-friendly; DAVID feels more like a long-established neurotechnology toolset.
A user who wants a clean app and guided routines may prefer NeuroVIZR. A user who wants established AVE categories, physical controls, CES options or the Premier’s advanced stimulation architecture may prefer DAVID.
DAVID versus NeuroSync Pro Audio+Light
DAVID devices are dedicated hardware systems. NeuroSync Pro Audio+Light is professional software for creating custom audio/light sessions with external RGB-W lighting. The workflow difference is decisive.
| Aspect | DAVID devices | NeuroSync Pro Audio+Light |
|---|---|---|
| Primary workflow | Select pre-programmed session on dedicated hardware. | Design a session with timeline, keyframes, music, colour, frequency, intensity and effects. |
| Light output | Eyeset-based stimulation. | External DMX/Art-Net RGB-W lighting and room-scale setups. |
| Professional strength | Pro/Premier add CES and advanced stimulation options. | Deep authoring control and immersive space design. |
| Customization | Higher on Premier, especially with DAVID Studio. | Native visible graph-based authoring inside the session creator. |
| Best use | Portable AVE/CES style sessions. | Custom Audio+Light experiences for practices, studios and created sessions. |
The practical distinction is simple. DAVID is excellent when you want a dedicated device with established sessions and, on higher models, electrical stimulation options. NeuroSync Pro Audio+Light is stronger when you want to design the entire audiovisual journey yourself and drive external lighting in a room.
Which DAVID model should you choose?
- Choose Delight if you want simple AVE with the fewest decisions and the lowest DAVID entry cost.
- Choose Delight Plus if you want AVE only, but with more session variety and gamma-oriented options.
- Choose Delight Pro if you specifically want AVE and CES in one portable device and you are prepared to use CES responsibly.
- Choose Premier if you need the most advanced DAVID platform: colour-rich Spectrum eyeset, display, session information, programmability, CES, MET and optional tDCS.
Safety and responsible use
All rhythmic light systems require care. People with photosensitive epilepsy, seizure disorders or unexplained loss of consciousness should not use flashing or rhythmic light without medical clearance. Users should also be cautious with migraine, severe anxiety, panic vulnerability, dissociation, psychosis vulnerability or high sensory sensitivity.
With Delight Pro and Premier, add extra caution because CES, MET and tDCS are electrical stimulation technologies. Follow the official manual. Do not use electrical stimulation with implanted electronic devices, uncertain neurological history, pregnancy, serious cardiac concerns, active seizures or complex medical conditions without appropriate professional guidance. Do not combine devices or protocols casually.
Never use these devices while driving, cycling, operating machinery or doing anything that requires immediate alertness. Start with conservative brightness and volume. Stop if headache, nausea, eye pain, dizziness, panic, agitation, disorientation or unusual discomfort occurs.
DAVID devices, NeuroSync Pro, Kasina and NeuroVIZR should be described as structured sensory or stimulation technologies. They should not be presented as guaranteed treatments, diagnoses or cures.
Bottom line
The DAVID Delight, Delight Plus, Delight Pro and Premier form a logical ladder. Delight is simplicity. Delight Plus is broader AVE. Delight Pro adds CES. Premier is the advanced professional platform with deeper display, colour, programming and optional electrical modalities.
For personal light-and-sound use, the Delight or Delight Plus may be enough. For practitioners who specifically want CES, the Delight Pro becomes relevant. For clinicians and technical users who want the broadest DAVID feature set, the Premier is the flagship. The right model is not the one with the most features; it is the one whose complexity matches the user’s goal, skill and safety context.
