At your facility who is the keeper and handler of the microphones?
If not monitored and controlled a $600 headset will get just as bent, broken, destroyed and lost as a $50 headset mic, at least until that happens the $600 mic will sound better!
One thing I don't like about mics like you pictured in your first post is the use of the long barrel adapters for different body packs. The long barrel puts a lot strain on the body pack connector when people lean over or sit on the body pack.
Well, the only people who are authorised to operate the sound system are the trained sound team. When people hire the hall and require sound, we provide someone to run that (for a fee of course). The headset mic is for the Pastors use exclusively. That's the rules. What actually happens, is anyone's guess.
I couldn't find an image of our actual mic. While the mic body is similar to the image I linked, the plug is shorter, being permanently attached to the lead. We used to keep the mic in a plastic clip lid container but I found the lead damaged from being pinched in the lip a few times. Now I have it in a larger cardboard box and the lead rolled up on a large foam cylinder so there are no sharp bends in the lead. If I find it not rolled neatly on the foam.
