I’m new here, but I now have experience with the Jabra Pro 10’s and Android, and I know exactly what you are referring to. It’s really the only problem I have with these hearing aids. What I’ve found is that it is due to the very poor range of the Bluetooth receiver in the hearing aids. If you hold the phone close to your ears, everything works great. I hold the phone up near my face when making phone calls. For streaming, I can usually get away with having my phone in my jacket pocket and everything works good. In pants pocket it can sometimes start to cut out or give that “localized” effect you are talking about.
Even with this problem, the Jabras are way better than the Oticons I tried from an audiologist. Those things would disconnect all the time, and the app was horrible. I love the Jabra app and the hearing aids work good with my ears. I am hoping they can up the Bluetooth receiver range in the future. (Just let Jabra use their own receiver instead of using Resounds)
