Sony ECM-77 Overview

The black Sony ECM-77 is a miniature omnidirectional lavalier microphone designed for professional broadcast, sound reinforcement, and recording applications. The condenser mic element's tiny profile allows 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, helping to provide consistent levels, even if the talent isn't speaking directly toward the mic.

The ECM-77 provides a wide frequency response of 40 Hz to 20 kHz for accurate reproduction of speech and vocals and requires 1.1 to 10 VDC power from a compatible wireless transmitter or similar device. A windscreen to reduce wind and breath noise and a tie clip to attach the mic to clothing are included.

Unterminated (Pigtail) Leads
Customizable Wiring
  • Pigtails: Works with Sony transmitters equipped with This version of the mic features unterminated pigtail leads allowing for custom wiring.
  • Third-Party Devices: The ECM-77 will work with many third-party wireless transmitters and portable audio recorders that are equipped to supply 1.1 to 10 VDC through a Sony wiring configuration.
Dependable Performance
Small Size
The ECM-77's capsule is 1/4" in diameter and 1/2" in length, allowing the mic to be used on stage or on camera while remaining inconspicuous.
Headroom for Standard Speech and Vocal Applications
The mic can handle up to 120 dB SPL without distortion—adequate headroom for most presenters, performers, and instructors.
Omnidirectional Polar Pattern
The forgiving omnidirectional polar pattern picks up sound from all around the mic and provides a consistent frequency response, even for off-axis sound. This helps to supply clear, intelligible speech and vocals, even when the talent turns away from the microphone.
Wide Frequency Response
With its 40 Hz to 20 kHz frequency range, the ECM-77 provides accurate and transparent reproduction of speech, vocals, and instruments.

Sony ECM-77 Reviews

Better Than Expected

By Andy
Rated 5 out of 5
Date: 2025-02-04

I have the Sony URX-P03D and two URX-B03 Transmitters and have been using them with the supplied Lavs ECM-V1BMP. These have worked pretty good with My Canon XF400. But with my new Fuji X-H2s, the background hiss noise level was extremely noticeable, even when I lowered the X-H2s Mic gain -12db and then raised the output from the Sony RX. Not very usable at all without much noise reduction work in Premiere. Then I simply replaced the original mic with the ECM-77. WOW! Background hiss is almost entirely gone, and the ECM-77 produces about a 4-5 dB higher levels at the same gain settings. The ECM77 sounds better than the specs may show. I can now avoid purchasing a Tascam CA-XLR2d-F unit for my camera.

Caps go bad regularly

When it's working, it sounds great. The problem is, we use this product 10+ hours per day for live news broadcasts, and they are not robust enough. We have had 5 caps go bad in just as many months. Never seen anything like it. Costing us a lot of money to have to replace on a regular basis. I'm going to dish out more money this time for the Sanken mic in hopes that it will have a longer life.

If you had to do it again, would you still buy this over the cos-11d?
Asked by: Angelito
The Sony ECM-77 Miniature Omnidirectional Lavalier Microphone with Locking Sony 3.5mm Connector and Sanken COS-11D Lavalier Microphone are both high-quality, professional microphone choices. Selection between the two is mostly a matter of personal preference but can also be influenced by application, continuity, and compatibility.

Would this work on the Tentacle Track E?
Asked by: Angelito
Found answer to my own question but sharing for others who may find it useful: This lav can work with other devices if the device can supply 1.1 to 10 VDC power. The Tentacle Sync Track E has a mic plugin power up to 5V so it can work with this lav mic.

question

I have a wireless lavalier mic system. The microphone is model sony emc77BMP and the receiver is sony wrt 805.It is not working well, since it catches a lot of interference when recording on longer distances that 30cm, and especially in the city, and as such the wireless part of the system is practically useless for me, but the lavalier mic is very good, and I want to connect it directly to my field-recorder a Tascam DR-40. The input in the recorder is XLR, while the lavalier has a jack (male). I need an adaptor from jack to XLR, and I am wondering about 2 things:1) The adaptor should be a jack (female) to a XLR (male), but is anything else needed, like a converter of electric tension between the lavalier and the field-recorder, or does the lavalier connect directly to the field-recorder?2) The field-recorder offers different settings for recording. One option is to record directly, and one option is to record using phantom-power. Which option should I use when connecting the lavalier directly to the field-recorder via an adaptor (omitting the wireless receiver and emitter system)?
Asked by: John D.
The lav can plug directly into the DR 40. All you will need is a 3.5mm to XLR adapter and phantom power from the recorder. Then you can plug the lav directly into the XLR mic input on bottom of the DR 40. B&H # QUQAD2 see below.

question

Could this microphone also be used with the Tascam DR-70D?
Asked by: Thomas
Just heard back from Tascam and they confirm that plug-in power is about 3 volts. So mike would have to go through wireless and then into Tascam via XLR.
