When the words "stage microphone" are used, I'm pretty sure people thought of this
However, that isn't the type of microphone that I think the item was intended to be. I think it is intended to appear more like this.
That is Ruby Rhod (I hope I got the pictures right) wearing a wireless stage microphone as well.
Which would follow what the description of the microphone already is. It is a very light (approximately 1KG) wireless microphone that is clipped to the belt in the back, with a wire running up the back under clothes to a face microphone. This is what actors and actresses wear on the stage, hence a "stage" microphone. And this is exactly what the physical description of the item is, including the clip for the belt.
Hence why I think the microphone was designed to be wearable to give a performance with your hands free, but somebody just forgot to code in coverage for face and back.
But... why? Stealth rappelling is iconic.

There are quite a few things that seem like they could be comparably difficult to say, taking a sword out of someone's pocket while standing behind them in their apartment, but that would automatically break stealth now regardless of stats. It would make sense to me if there was some gradient there.
I personally think using hooks while stealthed is awesome and would prefer it if this was possible with enough skills/stats. This would be my first choice. However, it it's decided that's not okay, maybe go with a soft break instead of a hard break (if that's not already the case).
