Looks like a Speaker, works as a Stealth Recording Blocker.
Introduction of the Anti-Recording "Bluetooth Speaker" U-136
This device is engineered as a professional-grade solution for preventing unauthorized audio capture during private discussions or high-security meetings. It emits a sophisticated ultrasonic pattern - silent to the human ear - yet powerful enough to overload the microphones in phones, recorders, and other listening devices. Once the interference blends with live speech, any attempted recording becomes distorted, noisy, and impossible to decipher. Its core purpose is to safeguard spoken information and block covert recording attempts. Designed for industries that demand strict confidentiality, the product highlights its strong voice-protection and anti-surveillance capabilities.
Advantages and Functional Features
- Enhanced Ultrasonic Interference System. A dense matrix of 136 ultrasonic emitters operates simultaneously to produce a strong jamming field that disrupts microphone input on smartphones, digital recorders, and similar devices. This creates a 360-degree protective barrier with an effective range of up to 8 meters, ensuring full coverage around a meeting table or within a room.
- Purpose-Built Design & Dual Use. Its slim, vertical form factor blends naturally into offices, conference spaces, and other secure environments where privacy is critical. In addition to protective functions, the unit can be used as a conventional Bluetooth speaker for playing audio.
- Reliable All-Day Operation. Equipped with a 4-hour internal battery and full functionality while charging, the device delivers uninterrupted protection during lengthy discussions or continuous daily use.
- Smart Voice-Triggered Mode. To save energy and maintain discretion, the system can be set to activate only when it detects human speech, automatically returning to standby when the environment is quiet.
- Stealth Remote Activation. A compact remote control allows the user to enable or disable the jamming mode without physically touching the unit - ideal for covert operation during confidential meetings.
Applications
The Anti-Recording "Bluetooth Speaker" U-136 is designed for flexibility and performs effectively across multiple environments. Below are some key situations where it provides maximum value:
- Business Environments: Shield confidential company discussions and proprietary information from unauthorized audio capture.
- Public Sector Facilities: Keep sensitive negotiations and internal communications protected from recording.
- Private Conversations: Preserve privacy during one-on-one conversations at home or in private workspaces.
- Educational Institutions: Stop illicit recording during examinations or restricted staff meetings.
- Medical Facilities: Protect patient confidentiality and support compliance with privacy standards.

(*) Note: The mini-program supports independent control of 5 Audio Jamming Devices. It allows you to turn the Recording Blocker Devices on and off, adjust their power, and provide information on their current status and battery level. Using the program allows for a higher level of stealth in the use of Audio Jammers, compared to a standard remote control.
