After 25 Years, An Industry Standard


from New York, NY  -  Experienced

Over the years I've acquired a small arsenal of microphones from the very expensive (costing over a thousand dollars) to the basic inexpensive models. Years ago while working on broadcast productions, I came across this industry workhorse beauty after hearing the clarity and richness of the broadcast sound in many early productions. When I inquired, the microphone was the Sony ECM-55b.And it was a staple in tv and productions. I own a few of these microphones. As time goes on, they seem indestructible! They've been tossed about, stomped on, rained on, abused by amateurs ... you name it .. even chewed on by pets. Like the old Timex Watch ads: "They keep tickin and take a lickin." Many times, when I can't decide amongst my expensive mics, I reach in my bag for this one. Even If you have a flip style cam, grab yourself a XLR to mini plug for a few dollars and with the Sony,you've just added pro style sound to your production. After auditioning microphone after microphone for a series I'm filming this month, again I've chosen this microphone.You can't beat the quality built into this baby. Sony certainly got it right this time.


Excellent microphone


from Urbana, IL

I currently run the sound at my church, and my pastor has been using this model for almost 35 years on his wireless mic system. This microphone has excellent pickup, and a great response for the speaking voice. I hardly ever need to use an EQ on it. This is a very good buy!
