Is there any difference between a lavalier microphone with a charging case and one without a charging case?

The difference between the two is as follows:

1. Charging function: The lavalier microphone has a charging compartment that can provide charging function, which is convenient for users to charge and extend the use time. Lavalier microphones without charging compartments need to be charged in other ways, such as using a charger or battery.

2. Portability: Lavalier microphones with charging compartments are usually small and easy to carry and store. Lavalier microphones without charging compartments are larger and less convenient to carry.

3. Usage time: The lavalier microphone with a charging compartment can provide additional power through the charging compartment to extend the usage time. A lavalier microphone without a charging compartment needs to replace the battery or recharge it after the battery is exhausted, and the use time is relatively short.
