There must be a difference for the potential to get shocked. German repair shops must use isolating transformer, to safeguard galvanic isolation! Btw. galvanic isolation also is the reason, that even cheap measuring bridges with a laboratory power supply, still need a battery. Direct current voltage <= 60 V and alternating voltage <= 25 V are values that in Germany are considered as riskless, for medicine there are anyway other values. The advantage of microphones with metal cases that are hot is, that nobody will sing or speak to close to the microphone ;p. Ok, some times a proximity effect is wanted, but usually it's a PITA that so many idiots touch the mics with their lips.
