Our take on the Sony ECM-90LM Ultra-Compact Dual-Diaphragm Electret Condenser Microphone

The Sony ECM-90LM is an ultra-compact omnidirectional electret condenser lavalier mic built for clipping to a shirt or lapel. Its dual-diaphragm capsule picks up sound evenly from all directions, so the speaker can turn their head without dropping off-mic. It is a wired lavalier aimed at interviews, vlogs, presentations and stage work, and it suits people who want a discreet clip-on mic without wireless gear. Against wireless lavalier systems it is simpler and lighter, but it needs a cable to a recorder, camera or PA, and it lacks the bodypack and transmitter of those kits.

Questions and answers

Is the ECM-90LM good for recording speech?
Yes. It is an omnidirectional electret condenser made for voice, so it captures speech clearly when clipped near the collar. It is not designed for loud instruments or distant room capture.
Does it need a battery or wireless receiver?
No. It is a wired lavalier that runs on plug-in power from the device it connects to. You plug it into a camera, recorder or PA input and it works.
Will it pick up background noise?
It will pick up more of the room than a cardioid lav because its pattern is omnidirectional. Close placement on the chest keeps the voice ahead of the room.
Can I use it with a phone or laptop?
Only with the right adapter. The mic ends in a standard audio plug, so a phone or laptop needs a compatible input or adapter to accept it.
How does it compare with a wireless lavalier system?
It is smaller, lighter and simpler, with no batteries or pairing. A wireless system costs more and adds a bodypack and receiver but frees the speaker from the cable.
What is in the box?
The package centers on the microphone itself with its cable and clip. Check the listing for any included pouch or windscreen before you buy.
Where is the Sony ECM-90LM Ultra-Compact Dual-Diaphragm Electret Condenser Microphone cheapest?
At Best Buy, for $498.00, as of our latest check.
