Fantastic quality for public speaking. I'm a bit of a perfectionist when it comes to mics and at 1/4 the price of quality ear hooks I was concerned that the quality might not be good enough. But my fears were unfounded. The mic is excellent and with a little mid EQ the sound is crisp and clear. The output gain also seems spot on - powerful but not intrusive. Overall I would rate the sound quality of this model at 90% compared to the most professional versions on the market. A great buy for the price! In fact, I liked the first one so much that I even bought the second one as a replacement for our church. My only suggestion for the manufacturer would be to include a second/spare collar clip in the box or at least make it available for purchase through myself. Within two weeks one of our speakers accidentally fell and lost the clip. I had to buy mini clothespins to use as a makeshift collar clip. They work, but not that easily.
