usbroway 3.5mm Surveillance Coil Tube Earbud Kit 10 Pack

Ten-Pack Surveillance Earbud Kit

This ten-piece kit supplies 3.5 mm listen-only surveillance earpieces for two-way radios, speaker microphones, remote mics and MP3 players. Each unit uses a coil-tube acoustic design with a reinforced clip that secures the cable and removes strain from the earphone. The polyurethane-jacketed construction is built for rugged daily use. All pieces are fully compatible with original equipment manufacturer parts.

Suits Teams Needing Discrete Audio

Security personnel, event staff and marine radio operators who require private, receive-only monitoring will find this kit practical. The 32-ohm impedance and 0.1 W rated input match standard radio accessories. Users who need push-to-talk transmission, a different connector size or wireless operation should look at other configurations.

32-Ohm Impedance Defines Compatibility

The 32-ohm output impedance determines which radios and audio sources the earpieces can drive cleanly. With a 72 dB output level and 0.2 W maximum input power, the specification sets the electrical match required for clear, distortion-free listening. Verify that your device supports this impedance before deployment.
