Very Pleased


from Indianapolis, IN  -  Experienced

I haven't really tried out all the features of this microphone, but so far, I'm pretty happy with it. It allows for changing the frequency settings in extremely small increments, like 0.25 Hz or less. So you don't simply have to stick with just a few channels. The clip on this microphone is also quite a bit different than I'm used to on most lapel microphones. Instead of an "alligator" style clip, it's a molded plastic clip that just slides on to the speaker's clothing. That also makes the cable last much longer, because people can't clip it on to the cable and break it.
