I'd would first like to thank all for taking some time to halp explain some microphone features, all comments have really made a difference in where, how and what I looked for in a headset mic. Secondly, I thank Matt for pointing me here because he new where I would get straight forward, profesional advice for my microphone questions..
And my selection was (bbrrbrbbrrbrrrr.......) Shure WH30! Thanks to L&M, and Lawrence at D&D sound, I have a barrage of microphones here, that I tediously put through the grinder, and really pushed boundaries as far as which mic has the punch, power, versatility and could deliver a sound as good, or nor better than the trusty 421 and 58/ 58A. The WH30 is comfortable, with a flexible "gooseneck" boom allowing for perfect positioning and excellent definition, very similar to that which I was receiving from my 421. The really sweet thing that i have discerned from using the microphone is that "manipulation" can be overcome without driving volumes to high and without maxing low and high end frequencies. with the mic positioned just correctly, there is virtually no audible difference from a cupped mic, to the bare head set mic. I really didn't think I would ever be able to get that type of result from a headset mic, but the WH30 is not a beginner's microphone and sounds impressive.
For the trials, I used the head set version of the WH30, which I enjoyed for mobility features and "mute" on the battery pack in between uses. I will have to get used to moving the mic away from my mouth when I am between songs, otherwise I will end up saying something not intended for my audience to hear!
FINAL QUESTION- If I do decide to do the wired version of the WH30, I would still like to find a way to mute the mic between songs. Is there a device I can carry (much like the wireless pack) what can offer this feature?
