Technical Specifications

Engineered for compact, voice-driven devices, the ECM-DM1508K600 is a 15mm dynamic microphone capsule ideal for headset microphones, conference systems, intercom equipment, and handheld microphone assemblies.

Its tailored frequency response from 100Hz to 9kHz captures the vocal range with clarity while gently rolling off high frequencies to reduce noise and sibilance. The 600Ω impedance ensures stable performance across most voice amplifier circuits.

With a durable build and compact form factor, this capsule is well-suited for headset booms, gooseneck mics, handheld microphones, and voice pickup modules used in education, communication, and public address systems.

Reliability Tests

High Temperature Test: Microphone subjected to +60℃ ±3℃ for 96 hours with 20-50% humidity, followed by 6 hours of normal temperature lay.

Low Temperature Test: Microphone subjected to -25℃ ±3℃ for 96 hours with 20-50% humidity, followed by 6 hours of normal temperature lay.

Humidity Test: Microphone exposed to 40℃ and 90-95% relative humidity for 96 hours, followed by 6 hours of normal temperature lay.

Temperature Cycle Test: Microphone subjected to rapid temperature changes from normal temperature to +60℃ ±3℃ for 1 hour (normal temperature lay for 3 hours) and then to -25℃ ±3℃ for 1 hour (normal temperature lay for 3 hours).

Sensitivity Stability: Sensitivity remains within ±3dB of the initial sensitivity after each environmental test.
