Yes, you can put your earbuds in the case while it's charging. This is the intended way to charge most wireless earbuds. The charging case will automatically transfer power to the earbuds once they are placed inside.
Here are some additional points to consider:
- Charging Cycles: Frequent charging and discharging of batteries can reduce their lifespan, but modern earbuds and their charging cases are designed to handle this.
- Overcharging: Most charging cases have built-in mechanisms to prevent overcharging. The earbuds will stop charging once they reach 100% capacity.
- Case Battery: It's crucial to ensure that the charging case itself is adequately charged.
