    Shure MX391 reviews

    MX391W/C Microflex Cardioid Surface Mount Microphone (White) is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from Shure MX391W/C 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. Being mounted above the heads of the students and staff, the cardioid pickup pattern works great and helps to reject sound reflection from the ceiling. I had to build a TA4M extension cable in order to reach a wall mounted I/O plate, and another TA4F cable to reach the preamp, which I mounted beneath a countertop at the audio mixer in the adjoining room, but everything worked well. I've been using Shure products for many years, and they have never let me down.

    Rated 5 out of 5 by from Excellent boundary mic 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!
