The Bluetooth SE necklace and the tiny earpiece bug form a comprehensive covert communication solution that relies on wireless Bluetooth technology for greater ease of use.

The size of the earpiece guarantees discretion, as it is very easy to go unnoticed once placed in the user's ear.

The innovative design of the tiny earpiece, which is a special magnet that produces sound when placed near the transmitter, combined with the high sensitivity of the microphone and the device's volume, will satisfy even the most demanding users.
