The D-R5 “Noise Suppressed” covert wireless earpiece utilises custom designed audio signal processing, which has been developed to significantly suppress electromagnetic interference for the operator when carrying out foot or mobile covert surveillance, while maintaining the high quality of audio associated with Sonic covert wireless earpieces and systems.

The D-R5 system delivers both noise suppression and exceptional speech quality across the whole spectrum of covert applications, where standard inductive earpieces for example, may have rendered a particular type of vehicle unusable, due to the high levels of electromagnetic interference.

Micro D-R5 Wireless Earpiece Kit makes use of the Micro shell and contains the same technology as our D-R5X Wireless Earpiece.
