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

The Sony ECM-90BC is a tiny dual-diaphragm electret condenser lavalier mic built for clipping to a lapel or collar. Its dual-diaphragm capsule gives it a wider pickup pattern than a single-diaphragm lav, so it forgives slight head movement in interviews and presentations. It is a wired mic with a Sony-specific connector, so it suits owners of compatible Sony wireless transmitters and recorders more than general-purpose users. Compared with modern lavs, it is small and light but lacks the USB-C and 3.5mm flexibility of current rivals.

Questions and answers

What devices does the ECM-90BC plug into?
It uses a Sony-specific connector, so it is meant for compatible Sony wireless transmitters and bodypack systems. It will not plug directly into a phone, laptop or camera with a standard 3.5mm input.
Is it good for interviews and presentations?
Yes. The dual-diaphragm capsule picks up speech from a wider area, which helps when the wearer turns their head. It clips to a lapel or collar and stays out of frame.
How does it compare with a modern USB lavalier?
Modern USB lavs plug straight into computers and phones and often include adapters. The ECM-90BC is smaller and Sony-native but needs compatible Sony gear, so it is less flexible for general use.
Does it need phantom power?
No. It is an electret condenser powered by the Sony bodypack or recorder it connects to, not by separate phantom power.
What is in the box?
Expect the microphone itself with its attached cable and connector. Check the listing for a clip or windscreen, since bundles vary.
Where is the Sony ECM-90BC Ultra-Compact Dual-Diaphragm Electret Condenser Microphone cheapest?
At Best Buy, for $474.49, as of our latest check.
