Anyone have any issues using their Phonak Marvels outdoors?

And if you are streaming outdoors, forget having your phone in a pants pocket … I find that distance to the aids is much too far for uninterrupted Bluetooth. When outdoors I always have to keep my iPhone in the shirt pocket closest to my primary aid (so that the distance is no more than 10 inches). I have also noticed that wearing a leather jacket over my iPhone in a shirt pocket always interrupts the streaming, so the iPhone has to be moved to an upper jacket pocket!
