A great stage mic for a keyboardist because you can turn your head left, right, up, down and still sound excellent.

I saw that also. I've tried to like headset mics, but maybe I'm too old to change my ways!
Maybe I'll trade Gary something for his extra.

You can't work a headset microphone.. That's why I've always avoided them. You can get a wide variety of tones from your voice by moving in close and going soft, or moving back and going hard, and all shades in between.

But that headset mike is going to be at the same distance all the way through the song, unless you are messing with it.

Plus, how do you deal with a cough while you are playing? Or an aside to a customer?

I never liked singing with headset mics for all the reasons above....plus I dont like the way it looks & feels on stage...

Well sports fans, you can work a headset mic - it's called voice control. No, you cannot pull away the mic when screaming out those high notes that are above your vocal range, something I see done all the time. And, I would love to hear someone explain how moving a mic closer or farther away physically changes the tone or frequency of the sound entering the mic. Either you CAN use a headset mic - or you CANNOT! I have 3 Crown CM-311A mics and the vocal reproduction quality is superb. For a number of reasons stated many times in the past, I would never go back to a handheld mic.

For a cough or conversation with a customer, there's a mute switch on the belt pack - all you have to do is push it. Or, because the mic has an extremely short range, you can just reach up and move it a couple inches from your mouth and no one will hear you cough or speak.

Cheers,

Gary

You can always use compressor to tame those highs.

Well the tone does physically change because of the proximity effect. Getting closer to the mic boosts the low end frequencies. The spec sheets that come with most mics show this effect.
Some higher notes require more energy, even though they are not above the vocal range. Actually there are many times when lower notes require a little more volume for the situation, so backing off the mic helps there also.
The Crown mic does have some built-in compression. I tried it, but it wasn't comfortable for me.

This...

Plus, you are playing, and a cough comes on. What do you stop doing to move the mike - the chords, or the melody? LOL

Me, I just keep playing and move my head off the mike.

I saw a cool little box called a "cough drop" (I think) that was a momentary OFF button for the signal. Great idea, but I'm not a candidate either - I'm too mic intensive with that proximity effect, and I never liked the aerobics instructor look. The teeny-weeny ones we use for our actors on stage are very unobtrusive, but they're all omni-directional and would be terrible in my stage setting.

No headset mic for me, either, for all of the reasons given above. Hey UD, just imagine a four-part harmony cough! LOL!
