Benefits of the Sony ECM77B Microphone

Great things sometimes come in small packages. Get to know the discreet yet powerful Sony ECM77B Microphone further below.

Industry Standard

It’s not every day you’ll find a microphone that experts call an industry standard — especially in a competitive, technically challenging field like recording. But the ECM-77B manages it with style and functionality.

Housed in a sleek black casing, the compact device has accompanied radio hosts, field reporters, and broadcast journalists for decades. Featuring three different clips and a lightweight body (it weighs just shy of 1 lb.), this omnidirectional lav mic is discreet and comfortable while capturing the human voice accurately and reliably. This has made it a mainstay for television broadcasting channels, including the BBC.

Of course, anyone with the capacity to invest in this device can benefit from it, whether they’re a hobbyist or a seasoned pro. It’s also much better than your average Zoom recorder, so if you’re looking to upgrade your audio tools and the Sony has captured your eye, we say go for it.

Crystal Clear Audio

The miniature lav mic features an omnidirectional polar pattern and a condenser that primes your vocals even before editing, delivering crisp and full-bodied tones for everyone to hear.

Any audio pro can attest to the quality of the vocals produced by the ECM77B. This is in no small part due to the wide frequency range of the microphone, which gives it the ability to pick up voices, amplify them, and then mute background noise in one fell swoop.

We’ve tested it in different rooms with varying acoustics, as well as outdoors where there are plenty of environmental obstructions, and it did not disappoint. The ECM 77B is able to function at its peak no matter where you are, although we observed it worked at its very best indoors. For outdoor settings, users can install the windscreen that comes with the package to filter out explosive consonants and moving air.

Compact and Discreet

Lavalier mics, or lapels, are much more compact than handheld devices. This makes them perfect for field reporters and podcasters on the go who don’t want to miss out on recording a spontaneous conversation. It’s also a viable option for live music performances in small spaces, filmmakers, teachers, and more.

The wire of the Sony ECM77B is also long enough that you can still move around a little without the risk of unplugging it. You also have the freedom of placing it where you like on your person and not be limited to a single spot, whether it’s on your tie, collar, or waistband.
