Q:
What is the nominal level of the Shure SM10A headworn microphone? It seems a little bit low, is there something wrong with my mic?
 
A:
The nominal level for this mic is -65dB, comprared to a 'typical' vocal handheld mic which has an output level between -50dB and -60dB, it can be a little softer output than a handheld. This level is just the specification of the mic and your situation may greatly vary the actual output level.
