Excerpt: I vertically mounted this mic on a wall in a medical treatment classroom. It was to be used to hear conversation and responses by an observer in an adjoining area. I needed something unobtrusive and with enough sensitivity to provide clear audio, but without too much ambient noise. The MX391 is small, and the white color helps it to become almost invisible on the wall.
Pros: Clear Sound, Compact, Durable, Easy To Use, Lightweight, Versatile
Excerpt: 4 1/2 stars. These mics perform as you'd expect. I use two of them to record audio on typical conference room tables. Used with both Mackie 402 mixer and a Sound Devices 302. Excellent results with both. Obviously the further away someone is from this mic, the more room sound you get. With 2 of these mics I've recorded 12 people around a conference room table very good results. Fairly good price on them as well. Overall, very good value.
Excerpt: This is astoundingly good boundary mic for ~$. Much more solid, heavy, and elegant (both the mic and the inline preamp unit) than I expected. Pattern and noise are just as advertised. For most conference room applications, the room noise (computers, AC, etc.) is going to be much louder than the self-noise of these mics. I will probably pick up more. This version does NOT have a mute button, BTW. B&H delivery and pricing were top notch, per usual!
Pros: Elegant, Great Pickup, Long Cable, LOW NOISE, Well-made
