Selection Principles
Polar Pattern
Unidirectional for headset applications — rejects background noise and feedback, focuses on user's voice.
Impedance Matching
150Ω/600Ω dynamic mics for aviation/industrial. 2.2kΩ ECM for consumer headsets. Match to your amplifier input.
Wind Noise
Helmet applications need wind noise resistance. ECM-B6027UL50-23702 optimized for open-face helmet use.
Durability
Robust solder joints and flexible cables — designed for daily headset wear and tear.
Performance Standards
Voice-Optimized
Frequency response tuned for speech intelligibility.
