Key Highlights
  • MS Shotgun Electret Condenser Mic
  • Switchable Monaural/Stereo Operation
  • Compact & Lightweight design


The Sony ECM-680S MS Stereo Shotgun Electret Condenser Microphone is ideal for a broad range of field production and broadcast studio applications. Incorporating newly developed microphone capsules, the ECM-680S offers excellent sensitivity, low inherent noise, and a flat-and-wide frequency response. The most versatile feature of the ECM-680S is its switchable operation between a highly directional monaural mode and stereo mode.

Monaural mode provides highly directional sound pickup, while stereo mode delivers natural spatial sound. The ECM-680S is compact and lightweight, making it well-suited for use with a range of Sony professional camcorders. It can also be mounted on a boom pole.

Superior Sound Quality

The ECM-680S uses the Mid-Side (MS) technique that offers natural stereo sound and excellent localization. Equipped with newly developed large diaphragm microphone capsules with bidirectional characteristics, the ECM-680S delivers a superb sensitivity of -28 dB1 (stereo)/-32 dB1 (monaural), and extremely low inherent noise of less than 20 dB SPL (stereo/monaural). 

Switchable Between Stereo & Monaural

The ECM-680S can operate in either stereo or monaural (uni-directional) mode2, allowing it to be used in both EFP and ENG applications. Stereo mode is ideal for capturing environmental sound with natural sound quality, while monaural mode is ideal for clearly capturing voice and sound from a distance. These modes can be selected from the switch on the microphone or via compatible Sony professional camcorders3. The LED on the microphone lights up when the ECM-680S is set to stereo mode to clearly display which operating mode is currently selected. 

Flat & Wide Frequency Response

The ECM-680S microphone has a flat-and wide frequency response (50 Hz to 20 kHz stereo/40Hz to 20 kHz monaural) in both stereo and monaural modes, and will provide sound reproduction that is extremely smooth and natural.

Compact & Lightweight

The ECM-680S has been designed to be a compact yet high-performance stereo shotgun microphone, ideal for camera mounted use. It measures only 9-7/8" (25cm) in length and weighs less than 0.3 lb (140 g), maintaining good balance and mobility when mounted on a range of Sony professional camcorders.


1 0 dB=1 V/Pa

2 MS microphone signal of th e ECM-680S is internally decoded to L and R (stereo) outputs.

3 Stereo and monaural modes can be switched from the Sony HDW-F900R CineAlta camcorder, HDW-790 HDCAM camcorder, and PDW-F350/F330 XDCAM HD camcorder.
