With both wireless and wired connections available, the ECM-S1 portable streaming microphone is a compact and lightweight high-performance unit that provides clear, low-noise, minimum audio delay, high-quality audio for easy recording or live-streaming either indoors or outdoors.

• High-quality microphone capsules for clear voice recording: Despite its compactness and light weight, the ECM-S1 is equipped with three large-diameter (14 mm) microphone capsules that provide clear, high-quality sound recording with a flat frequency response.
• Low intrinsic noise levels deliver clear sound: The low intrinsic noise and wide dynamic range of the microphone allow clear capture of even low-level sound.
• Directivity selectable to suit the scene: Three directional sound capture modes are provided: Uni-directional, Omni-directional, and Stereo. A switch on the side of the microphone allows the user to select the appropriate directivity for the current scene or usage situation.
• Noise-suppressing filter functions: A digital noise cut filter removes persistent background noise, and a low cut filter on the microphone side reduces unwanted low-frequency sound from wind, air conditioning, and vibration.
• Pop guard to suppress popping noise: A pop guard is included to prevent the annoying popping sounds that can occur due to vocal plosives when the microphone is placed close to the speaker's mouth, allowing vocals, narration, and other audio to be recorded under optimal conditions.
• Compact, lightweight body design: The ECM-S1 comprises compact and lightweight microphone / transmitter and receiver units that provide excellent functionality with high digital sound quality. It can be used in a wide variety of environments, both indoors and outdoors with a camera.
• Operability for real-time confirmation and adjustment: An independent AUDIO LEVEL dial allows real-time adjustment of the audio input level with the upper dial. In addition, the connection status between the microphone and receiver can be checked with the LINK lamp.
• Suitable for long hours of outdoor shooting: The receiver and microphone each have built-in batteries. The receiver can be used continuously with direct power supply when connected to the camera's Multi Interface (MI) Shoe or to a PC or other device.
• Wireless transmission with low latency and high sound quality: Bluetooth 5.3 and a LC3plus codec provide low power consumption, low latency, and high sound quality.
• Supports a variety of mounting and attachment methods: The microphone can be attached to a stand during recording, and the angle of the microphone can be adjusted back and forth.
• Multi Interface (MI) Shoe for minimal audio delay and cable-less power supply: Connecting the receiver to a camera from Sony that supports the Multi Interface (MI) Shoe, such as one of the α series digital interchangeable-lens cameras or vlog cameras.
• Wireless sound recording in conjunction with a camera: By connecting the receiver to a camera from Sony that supports the Multi Interface (MI) Shoe with a digital audio interface, high-quality audio can be captured and transmitted digitally without degradation.
• USB digital audio output: Both the microphone and receiver are equipped with a USB Type-C port that provides 48 kHz / 24-bit digital audio output. This enables the microphone to be connected to a wide variety of devices, allowing for filming and streaming with a variety of connection methods.
• Microphone audio input/output via 3.5 mm mini jack (stereo): A 3.5 mm mini jack (stereo) is provided for audio output from the receiver, allowing use with cameras, PCs, IC recorders, and other devices not equipped with a Multi Interface (MI) Shoe.
• Audio monitoring with headphones: The microphone is equipped with a headphone output jack, allowing audio monitoring via headphones (sold separately) during recording via USB connection.
• Expansion of Sony's microphone lineup: With a wider selection of Sony microphones available, you can now choose from a broader range of options depending on the situation and application in which you wish to use the microphone.
