Right side disconnecting after 2 minutes connected

My air pods pro are charging correctly but, since the day i bought it 3 months ago, the right side keeps disconnecting after 2/3 minutes of use. If I put it back inside the case for some time and then reconnect in my ear, the same thing happens, in some minutes it disconnects again. I already tried to fix it by forgetting the device on my iPhone and pairing it again but it doesn’t worked.
