iPhone has static on Bluetooth calls

When I’m on a call with my fiancé she always says wow that so loud and annoying. Just wondering if others had this issue and how to fix it. I tried messing with the volumes on radio and phone both. Didn’t help. Thanks

 

Does it happen with other people when you call them?

Did you piss her off recently?

 

Haha. No has happened every time we talked. She told my son to tell me it’s loud too when she had on speaker. My friend said he heard something when I asked after a call . I don’t call many people besides my family. Just weird to me that doing that

 

Have you tried to restart calling? When you have the problem: when you call her or when she calls you? All in all, you can bring your IPhone to the service centre.

I wonder how she thinks your son could change the situation ...
