The SENNHEISER's MKE 2 EW is a lavalier condenser microphone with dual-diaphragm construction resists sweat and moisture, and its small size makes it easier to conceal, even when buried in clothing and costumes, it resists touch and rustling noise. The MKE 2 lav provides crisp, comprehensible reproduction of speech, dialogue, and vocals with its wide 20 Hz to 20 kHz frequency range and capacity to tolerate up to 142 dB SPL. The omnidirectional polar pattern of the microphone picks up sound from all directions around the capsule, allowing for stable levels even when the talent turns away from the mic capsule.
