Protect conversations. Protect information. Protect privacy.
In a world where almost everyone carries a smartphone, confidential conversations can be recorded without anyone noticing. A phone on the table may be much more than a communication device — it can also contain microphones and recording applications capable of capturing sensitive conversations.
The CryptSec AJB-332 Dual Phone Recording Blocker provides a simple and professional way to reduce this risk. Designed to protect smartphones from unauthorized audio recording, the AJB-332 uses advanced ultrasonic mixing technology to interfere with smartphone microphones while allowing the phones to remain connected to their networks.
Whether you are discussing business strategy, legal matters, personal affairs, security information or other sensitive topics, the AJB-332 helps create a more private environment for the conversation.
Privacy protection for the modern smartphone
Smartphones are everywhere — at home, in offices, meeting rooms, boardrooms, hotels and government facilities. That means privacy protection should not be limited to large corporations or high-security environments.
The AJB-332 is designed for anyone who has conversations they do not want recorded without their knowledge.
Private individuals, companies, lawyers, consultants, organizations, executives and governmental agencies can all benefit from having a dedicated phone recording protection solution available when confidentiality matters.
Two smartphones. One secure solution.
The AJB-332 has two dedicated phone compartments, allowing two smartphones to be protected simultaneously.
Simply place the smartphones inside the unit and activate the device. The ultrasonic interference is designed to prevent the phones’ microphones from clearly capturing the surrounding conversation.
The result is a practical privacy barrier between a sensitive conversation and the microphones inside the smartphones.

Why is smartphone recording protection important?
Confidential information can have significant personal, financial, legal or strategic value.
A conversation may involve:
- Business strategies and negotiations
- Mergers, acquisitions and investments
- Intellectual property and research
- Customer and employee information
- Legal advice and case discussions
- Financial information
- Security procedures
- Government or organizational information
- Personal and family matters
- Sensitive negotiations or agreements
Traditional instructions such as “please don’t record this meeting” depend entirely on trust and compliance.
The AJB-332 provides an additional technical privacy measure by requiring smartphones to be placed inside the protection box during sensitive discussions.

The AJB-332 provides two internal slots measuring approximately 173 × 86 mm, designed to accommodate large modern smartphones.

1. Power on

You do not need to be a government agency or multinational corporation to have information worth protecting.
Every organization has confidential information. Every professional has conversations that should remain private. And every individual has a right to consider how their personal conversations are protected.
The CryptSec AJB-332 makes smartphone recording protection a practical part of everyday privacy and information-security procedures.
Keep it in the meeting room. Take it on a business trip. Use it when a conversation needs an additional layer of confidentiality.
