Battery
— one of the advantages of this type of power supply over batteries is that the built-in battery is a priori included in the standard package of tactical headphones, and when the charge is exhausted, it is enough to charge it again. Built-in rechargeable batteries often have a higher capacity than batteries. On the other hand, if such a battery runs out, it cannot be quickly replaced: it needs charging, and this requires time and external power.
