Neckloop with Microphone for Analogue, Digital and VSB
High Efficiency Neckloop with Integral Microphone in Beige or Black
Description
Designed to provide the magnetic field to drive to standard analogue and digital wireless earphones the Neckloop can be worn discreetly under clothing. Neckloops produce an even field and the volume in the wireless earphone will remain constant when the head is turned. It also incorporates a highly sensitive omni-directional microphone with very high immunity to chafe-noise that can be generated when the device is worn under clothing. The high-sensitivity of the microphone is of particular importance for eavesdropping during covert operations.
