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.

Havent used my purchase but very familiar with this product from use in television at various stations. Quality product. It goes without saying but it is easy to do and I have seen it multiple times, make sure you take the battery out.

I have used this so far for an interview indoors and echo is too a minimum and it is really easy to clip the mic onto the subject and included gear. I have also used it outdoors on a fairly windy day while doing a performance involving pouring water.

I conduct interviews for magazine articles and so I need nice, clean recordings for easy transcription. I am very pleased with this mic and will likely buy another one in the near future.

It has a bit of a large profile, but the sound is good.

I just received this wired lav. a week ago & had my first time using it yesterday... The audio coming through the camera was clearer than any other mic. I've used in the past. I like that it connects directly into the camera & I don't have to rely on a radio signal that is vulnerable toradio...

I do a lot of filming in the Holy Land and wireless mic systems are not always allowed. This EMC-44B is just what I depend on to maintain the same audio quality as the Sony wireless mic. I've also been a TV journalist for many years and this mic is all we used. Great for the price.

Love my lavalier microphones. They always give me the most professional sound. I have 5 of these microphones.

It's easy to know when it's time to replace these lil' guys, because the slightest move by your interviewee means horrible crackling in the headphones! I hate that, and I love that Sony keeps these moderately prices in the $100 range!
