Review: Fills a very small niche... within a small niche - My initial reaction to this microphone was that the gain was a tad low. It didn't pick up my voice as well as I would've wanted. Once I moved it from a direct connection to my recording device (a Zoom H4n) to a Behringer mixer I was able to boost the gain enough to make it useful. As my title suggests, once you get past the gain issue, this microphone still fills a very small niche, because it is a niche within a niche. Here's why. This microphone is a "Boundary Microphone", which is generally used to pick up ambient sounds within a small area such as a conference table or a church alter. Basically, you place a microphone on a flat surface, such as a table and your table actually becomes a part of the microphone, thereby extending the normal pickup to include sounds that otherwise can't be picked up. Some people place mics like this in very unusual places, such as on a wall or the floor to pick up the room sounds or footsteps (great for picking up tap dance) ... on a piano door, to get a more full bodied sound. In my case, I have the MX393/S version which is the "Super-Cardiod" version, which means the microphone picks up a very narrow area within the boundary, so it rejects more sounds on the sides than the other versions. This microphone feels solid and heavy, which is important for a Boundary Microphone. It stays where you put it, and assuming it were placed on the floor, it seems strong enough to withstand being stepped on from time to time.

*by J***S on 14 July 2015*

Awesome little microphones. We use them for theatrical performances in public parks. Just bought a second set. Pickup is great, sound is great. We have a set that has lived through a bit of abuse - like getting kicked around in the dark, slightly rained on, etc.
