Covert Surveillance Earphone sets a new standard for quality, discretion, and clarity, providing reliable communication across surveillance teams.

Designed to be worn on the left side, this Covert Low-Visibility Earphone Kit with 3.5mm Connectorfrom Otto is a low-profile earpiece designed to offer a low-profile audio solution that delivers clear intelligible sound for environments where discretion is called for, including crowd-control, military/government, law-enforcement, and security applications. The earpiece provides exceptional audio quality to ensure important information is communicated effectively, even in loud environments such as hotels, casinos, concerts, and event spaces. Ambient sound passes fully to the other ear, preserving binaural hearing for situational awareness.

When paired with Otto's Surveillance PTT (available separately), there's no need to raise the microphone or PTT to your mouth to send a transmission, providing a truly discreet communication solution that easily connects to popular radios and remote wired PTTs.
