Joelzed , via OnePlus 6T , Sep 25, 2021 : I'm using the OnePlus 6t and OnePlus wireless Z bass edition earphones. There is a cracking sound while attending calls on the earphones only. Im using another bluetooth earphones and the calls are good. Even used the earphones with other devices the earphones work fine. It's just when the wireless Z is paired with my 6T that the cracking sound on calls starts.
