Sony ECM-44B Reviews

Extraordinary Lavalier Microphone

By silvio
Rated 5 out of 5
Date: 2025-08-11

I used a Sony ECM-44B set of four microphones for the first time in 1995. Throughout the years I have tried other brands of lavalier microphones and no one compares to it. I have a few 20 years old units that still work. Although these are only entry level microphones in the Sony family, they are incredible reliable and super affordable. I use them daily, packing and unpacking them as I move from location to location and 30 years later, it is the only brand I use. I highly recommend this product.

question

Sound-wise would this be as good as a 77B? That is, if I don't need the smaller profile of the 77B would this 44B sound as good?
Asked by: Thomas
The main difference between the ECM 77B and 44B other than physical size, would be the frequency response. The 77B extends lower than the 44B, however generally for speech and broadcast applications those would be rolled off. If size is of no importance, the ECM 44B is a fine choice and very popular in broadcast applications.

question

How to connect Sony eco-44b to audio recorder
Asked by: Nicole M.
Hi Nicole, What audio recorder? The ECM-44B has a Male XLR connector. If the audio recorder has a female XLR port it will plug right in. If your recorder has a 3.5mm or inch input you will need an adapter:Hosa Technology Pro REAN XLR Female to 1/4 TS Hi-Z Microphone Cable - 10'https://www.bhphotovideo.com/c/product/828155-REG/Hosa_Technology_HMIC_010HZ_HMIC_010HZ_Pro_Mic_Cable.htmlOrKopul XRSM 3-Pin XLR Female to 3.5mm RA Stereo Mini-Plug Cable (1.5')https://www.bhphotovideo.com/c/product/1221867-REG/kopul_xrsm_015b_xrsm_3_pin_xlr_female.htmlRegards, -Erin

Would the 44-b use the XLR-Line or the XLR-Mic audio setting on the camera?
Asked by: Brian
The ECM-44B is a microphone, so it outputs mic-level voltage. You would want to use the mic level setting on your camera or recording device.

Will this mic work with Scarlett Focusrite 2i2?
Asked by: Gary
Should be able to work. Make sure AA battery is installed in the XLR barrel. Remove battery when not in use do prevent the Lav from damages from acid leaks. It's a great lav to have and audio is great. Have 2 for talking heads.

question

To link this to a DSLR with a 3.5mm jack in a way that adds to the length of the cord, I could use a 20' Kopul Premium Performance 3000 Series XLR M to XLR F Microphone Cable, plus a Kopul LMT100 - Low to High Impedance Matching Transformer, correct? The length will not degrade the sound, and I can go right into the camera?
Asked by: Brian
Correct. A standard XLR mic cable in addition to the Kopul LMT-100 cable will allow you to connect the ECM-44B directly to a DSLR. At this length would not affect the audio quality.

Connecting with the Kopul Low to High Impedance Transformer should the camera use the 3.5mm LINE or 3.5mm MIC setting?
