The Sony ECM-44BMP is an omnidirectional lavalier microphone designed for broadcast, sound reinforcement, and recording applications. The condenser element features a compact profile allowing it to be easily concealed in performance and broadcast situations. The omnidirectional polar pattern provides even frequency and sensitivity response at the direct and off-axis sections of the microphone capsule.

The ECM-44BMP provides a wide frequency response of 40 Hz to 15 kHz for accurate reproduction of audio signal from a variety of sources. The attached 3.9' cable features a 3.5mm locking mini jack for use with WRT-805 bodypack transmitters and UWP Series beltpack transmitters such as the UTX-B1 and UTX-B03. Phantom power is supplied via the connected bodypack transmitters. The ECM-44BMP includes a windscreen, tie clip, and microphone case.
