The Sony ECM-S1 wireless microphone with Bluetooth connectivity for streaming is a compact and lightweight high-performance unit that delivers clear, high-quality audio with minimal delay and low noise for easy recording or live streaming in both indoor and outdoor environments. Despite its compact and lightweight design, ECM-S1 is equipped with three large-diameter (14 mm) microphone capsules that deliver crisp, high-quality sound recording with a flat frequency response, especially in the low-mid vocal band, while eliminating noise. The outstanding sound quality significantly enhances the overall impression a well-produced video makes on viewers. The microphone’s minimal inherent noise levels and wide dynamic range enable it to crisply capture even low-frequency sounds. Ideal for streaming, the microphone is specially calibrated to sharply and naturally capture the rich texture of the human voice near the mouth. There are 3 directional sound capture modes: unidirectional, omnidirectional and stereo. A switch on the side of the microphone allows you to select the appropriate directivity for the current scene or usage situation. A digital filter removes background noise, and a high-pass filter on the side of the microphone reduces low-frequency sounds such as wind, air conditioning, and vibration, allowing for less noise reduction in post-production and improved workflow. An anti-pop filter is included to reduce annoying occlusive vowel sounds when the microphone is placed close to the speaker’s mouth, for recording voices, stories, and other types of audio under optimal conditions.
