YPA M1-C4S Clip-On Lavalier Cardioid Microphone - Compatible with Shure Wireless Mic Systems - Perfect for Interviews, Podcasts & Live Performances

I own multiple wireless units as I do location video work. I needed to add some lavs to our kit and tried this mic. It is unusable for any on-person application. The directional pattern attenuates so many key frequencies in the voice range that the only placement we found that was usable for this mic was to have the talent hold the mic in front of their mouth. Due to the directional roll off, we found it worked when attached to sources we needed to capture - for example it worked reasonably well clipped to the bridge of a mandolin. In summary not for voice applications at all.
