Pre-order | Global Launch of SONAR

In the world of magic, there are legends of a perfect system.

A tool so powerful it could achieve the purest forms of mentalism:

Hypnosis, remote viewing, mind control, seances, drawing duplications, invisible touches,predictions…

A system with a breathtaking set of features:

No Preshow

No Stooge

No Physical Contact

No Need for the Audience to Write or Draw Anything

For years, this has been the holy grail.

Today, the legend becomes real.

Introducing SONAR, a revolutionary performance ecosystem that transforms sound into a focused, invisible beam of energy.

Imagine a whisper, a thought, or a secret, projected through space like a laser, materializing only at the ear of your chosen spectator.

To everyone else, there is only silence.This is not a concept. This is a new reality for the professional performer. And after years of relentless development, we are officially opening the doors for a select group of pioneers to join us.

SONAR is not just a tool; it is the ultimate weapon for the modern wizard.

The Genesis of SONAR: A Mission in Reality

Many years ago, I was captivated by a high-tech scene in Mission: Impossible – Ghost Protocol. Ethan Hunt, played by Tom Cruise, and Benji, played by Simon Pegg, infiltrated the Kremlin using a cutting-edge device that could project sound with pinpoint accuracy, creating an auditory illusion to deceive a guard. That moment ignited a spark in my mind: was this just movie magic, or could the laws of physics allow for the creation of a real-world product?

This idea grew into an obsession. We began to explore whether it was truly possible to create a tool that could project sound like a beam of light, a marvel that could bring an “impossible” whisper to life in the midst of silence. SONAR is our ultimate answer to that very question.

From Inspiration to Innovation: The Story of SONAR

Our journey was inspired by the rumored techniques of the world’s greatest masters, effects so clean they were once thought to be possible only with actors.

This mystery, this pursuit of the impossible, became the foundation of our work.

Our path began in 2018 with ECHO, a device using bone conduction.

As Wayne Houchin said, “ECHO is terrifyingly good… a product with infinite potential and powerful effects.”

But behind ECHO’s success,we knew a higher peak awaited.

In 2019, we turned our focus to amore mysterious and potent technology:

“Ultrasonic Directional Audio Transmission”.

The road was not easy.

The SONAR project faced a global pandemic,financial strain, technical barriers, and countless setbacks.

But through it all, our belief in creating the perfect performance tool never wavered.

SONAR is the result of years of persistence, a testament to our relentless pursuit of excellence.

Project: E S _

ECHO and SONAR are not separate entities.

They are chapters in a grander vision: Project: E S _

E for ECHO, S for SONAR.

From covert receiving to directional transmission, they form a complete system for invisible audio control.

The blank space, _, signifies that this journey is far from over.

What can I do with it?

With SONAR, you can achieve miracles that once existed only in the imagination.

  • The Contract (EVP Manifestation): You can secretly transmit a ghostly voice or a mysterious message directly into a spectator’s recording device. While the room remains silent to the human ear, their phone captures an impossible Electronic Voice Phenomenon (EVP). When they play back the recording, a voice from the “other side” speaks their chosen word or answers their question, captured on their own device, in their own hands.
  • The Mask (PK Mind Control): Guide a spectator into a state of heightened suggestion. Then, using SONAR, you become an invisible puppeteer. Project untraceable commands—”lift your left hand,” “nod slowly,” “draw a circle”—that only they can “hear.” To the rest of the audience, the spectator moves as if controlled by an unseen force, their body responding to your will while you stand perfectly still, creating a chilling demonstration of mind control.
  • The Ringing (Auditory Hallucination): Make a spectator hear sounds that simply aren’t there. With SONAR, you can project the crisp sound of a bell from any location you choose, creating a perfect auditory illusion. The spectator will point to where the sound came from, stop in their tracks when they hear it, and swear to everyone that they heard it—even when you prove to all that the bell was never rung. You control their perception of reality, crafting a powerful and deeply personal hypnotic experience.
  • And more…

The Technology: Sound as a Laser

We’ve always known sound to be ripples.

But SONAR commands a different law of physics.

It transforms sound into an invisible, highly-focused beam of energy.

How It Works:

Loading the Sound:

We take a “whisper” or a “heartbeat” and load it onto an “invisible bullet”—ultrasound.

Laser Transmission:

SONAR’s transducer matrix fires this bullet, like a laser, along a dead-straight path.

Activation at the Target:

When this “sound laser” hits your designated spectator, it uses the physics of the air to create a virtual loudspeaker right at their ear.

The sound isn’t traveling from the device; it is born at your spectator’s ear.

A Modular Ecosystem:

Not only for performers with top-tier teams but also a complete arsenal for the solo artist

SONAR is not a single, one-size-fits-all device.

It is a modular ecosystem engineered for the modern solo artist.

Every component is designed for maximum impact with minimum footprint,empowering you to become a true one-person team.

SONAR x Host: The Core Engine

Actual Photo. Box Dimensions: 88mm*64mm*16mm

The source of all power.

We believe the ultimate goal isn’t to be the size of a deck of cards,but to fit comfortably inside it.

Supporting both TF card and Bluetooth modes, the Host proves that top-tier performance does not need to compromise on size.

SONAR xHost: Technical Specifications

Dimensions: 66mm x 66mm x 15.2mm

Weight: 64.4g

Battery Capacity: 400mAh

Carry Method: Magnetic Mount / Pocket Carry

Audio Source: Onboard TF Card / Bluetooth Device

Data Transfer: Type-C Cable

SONAR x6: The Stealth Module

The x6 is not a “basic” version;

it is a specialized weapon engineered for two distinct and powerful purposes.

For Direct Listening (In-Person Whispers):  

In quiet, intimate settings—a hushed theater, a private gallery, or a silent moment on stage—the x6 is your key to creating miracles.

Its ultra-compact design allows for complete concealment,even under a t-shirt in the summer.   

For Electronic Voice Phenomenon (EVP):   

This is where the x6 reveals its hidden genius. In any environment, it excels at transmitting sound that,

while imperceptible to the human ear, is captured with astonishing clarity by any electronic recording device—a spectator’s phone,a digital recorder, or professional EVP equipment.

This makes the x6 the most powerful, wearable, and deceptive EVP tool ever created.

Wear it comfortably under a T-shirt in summer, freeing you from the constraints of long sleeves.

This is the dream weapon for mentalists and close-up artists.

SONAR x6 Module: Technical Specifications

Dimensions: 61.9mm x 47.5mm x 19.8mm

Weight: 22.7g

Battery Capacity: 380mAh

Frequency Range: 400Hz – 10kHz

Effective Range: 0 to 5 meters

(in an environment with 40dB ambient noise)

SONAR x6 Module: Performance Environments Note To ensure you achieve the optimal effect in every situation, it is important to understand the two primary applications of the SONAR x6 module:

Direct-to-Ear Listening:

In scenarios for direct, in-person listening, the SONAR x6 is engineered to be clearly audible to a spectator in environments with an ambient noise level of approximately 40 dB or lower.

This is the ideal condition for creating intimate, whisper-like miracles.

Electronic Voice Phenomenon (EVP) Recording:

For EVP effects, the x6’s unique signal is designed to be captured with exceptional clarity by electronic devices (such as smartphones or digital recorders) in environments with up to 70 dB of ambient noise.

This is achieved because the recording device’s internal audio processing can gain and isolate the SONAR signal,

making it perfectly clear on playback even when it is imperceptible to the naked ear in the live environment.

SONAR x61: The Stage Module

When your arena is the stage, you need power.

But power should not demand compromise.

The x61 Stage Module delivers a massive audio punch with its 61-transducer matrix, yet it remains remarkably portable and versatile.

Forget heavy, cumbersome equipment.

The x61 is designed for the guerilla performer, allowing for seamless integration into your existing gear via its Hot Shoe Compatible mount.

This transforms your setup into a mobile, all-in-one broadcasting unit, perfect for the modern, agile artist.

SONAR x61 Module: Technical Specifications

Dimensions: 100mm x 100mm x 15.8mm

Weight: 261.5g

Its tactile feedback and intuitive layout allow for blind operation, letting you focus entirely on your audience.

SONAR xR (RF Remote): Technical Specifications

Dimensions: 69.3mm x 56mm x 15mm

The AI Face-Tracking Mount:

Your Intelligent, Autonomous AssistantThis is where solo performance reaches its zenith.

When paired with the x61 module,

our AI mount becomes your invisible partner on stage.

Its primary role in a solo operation is to provide flawless, automated targeting and calibration.Simply place it, point it towards your target area, and let the AI do the work.

It will automatically lock onto a spectator’s face, ensuring your “sound laser” is perfectly aimed without any manual adjustment.

If the spectator moves slightly, the AI will track and correct.

This allows you, the solo performer,to have absolute confidence in your setup and focus entirely on what matters most: your performance.
