Are you afraid of invisible microphones eavesdropping on your every word in private occasions? Now, this microphone blocker device that looks like a small Bluetooth speaker is here! It uses cutting-edge ultrasonic technology to completely block all bad recording attempts. Whether it is a mobile phone call, video conference, voice recorder or even professional equipment, it ensures that what is captured within a range of 2-6 meters will be messy and worthless audio fragments, making your conversation safe and impeccable.
Ultrasonic interference technology
P-F16 accurately disrupts the recording device by emitting high-intensity ultrasonic signals (120dB/30cm), making it unable to capture clear voice content. At the same time, it performs secure encryption processing to ensure that the audio data after interference is irreversibly damaged, completely eliminating the possibility of recovery.
Remote control switch
Supports a remote control range of 1 to 20 meters, allowing you to get rid of the tediousness and exposure risks of manual operation. Whether it is quietly started in the middle of a meeting room or temporarily turned off in a sensitive occasion, remote control allows you to take the initiative anytime and anywhere.
Intelligent voice control start and stop
Automatically standby when there is no sound, reducing unnecessary energy consumption.
Start immediately when there is sound to ensure real-time protection without omissions.
Stable and long-lasting battery life
Built-in 5200mAh large-capacity rechargeable battery, which can work continuously for 2-3 hours. With 4-hour fast charging technology, it shortens the waiting time and efficiently adapts to your usage efficiency.
Usage tips: scene matching, better effect
This product is suitable for recording interference of ordinary mobile phones and recorders, but does not support devices with advanced noise cancellation function (some professional recorders).
The good news is: except for iPhone, most daily devices do not have this function, so this device has extremely high adaptability in daily scenes.
