With my Phonak P70T I have custom molds, always had them since my first digital Ha’s 14-15 ears ago, before that I had types analogs, only once did they have to redo a new one for comfort reasons, the vent hole (1 in each) is supposed to be sized to your hearing loss, my receivers are 2P in both ears, I really have had no issues with them all this time. If they don’t fit after fitting my Audi will replace them.
