A friend of mine read my review and told me I had given only 3 stars, so I feel as if I need to update and change to 5 stars. I teach about 230-280 classes a year at the Y and this mic is still going strong after 4 years. I couldn’t possibly ask for more. I’ve kept the wording of my original review as written, because there really wasn’t anything to change. I did solve the “drooping” mic by wrapping the extended part with wire, so it always stays in place, but that doesn’t change the fact that “as is” you may have a problem with it falling a little. It still works better on the stereos that accept the larger size Jack than the smaller. But 4 years of good service for this price? 5 stars all the way.I use this mic when teaching Les Mills Bodypump classes at some local YMCAs. At one Y, the receiver part plugs directly into the stereo mic jack and the sound is EXCELLENT. At the other Y the receiver piece plugs into a wireless unit that is meant for another type of mic and the sound is not very good. So, the key thing to know here is that the sound may vary depending on your setup. The main reason I purchased it is that the transmitter is in the mic itself; I hate the wireless mics that have clip on transmitters that you wear at your waist. The headset fits well and can be bent to adjust to your head size. Several of us use this type of mic and some of my friends have had to use rubber bands to adjust for head size and those work well also. My only real complaint (and some of my friends have the same issue) is that the wire attaching the mic to the headset is not very stiff; the mic often falls below my chin and I have to readjust. That’s kind of a big deal, hence my rating of only 3 stars, but I still prefer this to any mic with a separate wearable transmitter. Other observations: Charging is easy and it always lasts through my hour long class (but I’ve never tested how long it will run on a charge). The case is excellent. I’ve never had an issue syncing the receiver and headset. I teach about 60 feet from the stereo and the connection is perfect.
