We have been using the Sony ECM44B lavalier mics for over 25 years in both studio and on-location productions. They last a long time, and are easy on the budget. We have periodically used other lavalier mics, but have never found any that work as well as the these for the price.

The mic was just as advertised. The ECM-44B is an industry workhorse and well worth having in your kit.

I've been using this style of mic for the last 15 years. It is perfect for interview settings.

I was tremendously disappointed in this mic. It was sold to me as being "industry-standard" - I'm not sure what industry that's referring to, but it surely can't be film.

I'd been getting by with a cheap lav for some time and started to have problems. I have XLR inputs on my Canon XA10 and wanted a mic with XLR output. The Sony is great and the AA battery lasts a long time and I don't have to deal with turning the mic on and off (and forgetting to turn it off).

I use this microphone to record video interviews. It doesn't make a lot of noise and sounds thicker than the wireless mics I've used in the past.

I've used Sony Lavaliers fro over 40 years. They are the standard. I would like a clip system similar to the TRAM microphone, but the traditional clip is fine. The ECM-44B is excellent quality and works as I expected.
