Hello, isabeau2603.
Thank you for using Apple Support Communities.
From reading your post, your AirPods are disconnecting when ever you answer a call. We'd like to help. How are you answering the calls? Are you using the iPhone or using the AirPods? Make and answer calls with AirPods on iPhone
"Answer calls with AirPods
Do the following to answer a call; do the same to hang up or switch calls:
- AirPods Pro: Press the Force Sensor on either of your AirPods.
- AirPods: (2nd generation) Tap either of your AirPods.
- AirPods: (1st generation) Double-tap either of your AirPods".
If this isn't the case, try resetting the AirPods: Reset your AirPods
Keep us updated.
Cheers!
