Spy earphones
Spy headphones are discreet audio devices designed for covert communication or unobtrusive listening. These miniature headphones, placed directly in the ear, are almost invisible and are commonly used in combination with hidden microphones or transmitter-induction loops. They are used in a variety of situations such as security operations, undercover investigations, examinations or presentations where it is necessary to unobtrusively obtain information or receive instructions. Spy headphones provide clear sound and ensure maximum discretion and privacy during use.
