The Bluetooth SE neckband and the Spy earbud form a comprehensive covert communication solution that relies on wireless Bluetooth technology for greater ease of use.

The size and color of the earbud guarantee discretion, as it is very easy to go unnoticed once properly placed in the user's ear.

Despite its wireless nature, the covert earbud boasts a very satisfactory battery life (3-4 hours per battery, with continuous use for calls), while the high sensitivity of the microphone and the device's volume will satisfy even the most demanding users.

The Bluetooth SE neckband itself is characterized by very long autonomy, as its battery can last from 4 to 6 hours, and it features Bluetooth for wireless connection to your mobile phone.

Combined with the Spy earbud, it will offer you excellent quality for your covert communication.
