Many power sources (like charger or power bank) are dynamic. So the label generally means "up to". 2A is usually for fast charging. So if a device does not support fast charging, the amperage will be reduced.
So a 5V2A power source will only transmit 5V1A to the headset because of the limitation by the headset.
