Key tactical features

Quad-microphone surround audio

The four independent microphones on the RADIANS R-3700 provide directional audio cues, helping shooters detect movement and verbal commands from multiple directions. That surround capability is especially useful on busy ranges or during team drills.

Smart amplification and impulse compression

Low-level sounds are amplified for improved communication and awareness, while the unit compresses and thresholds impulse noises—like gunshots—to protect hearing. The electronic circuitry preserves clarity without exposing the user to harmful peaks.

Practical design for field and range

Its compact folding feature and adjustable headband make the R-3700 easy to store and fit various helmets or caps. The LED onoff indicator helps avoid leaving the unit powered on and draining batteries between sessions. Bluetooth connectivity means it works wirelessly with most smart devices for streaming range commands or music during breaks.

Radian Weapons is a recognized name in tactical equipment, and the R-3700 reflects that focus on practical, mission-oriented design. The 24 dB NRR gives clear guidance on passive attenuation, and the blackgray finish keeps the profile low on any range or training environment.
