Sidney,
Hi. This changed with the new Phonak Paradise HA’s. They can “…simultaneously connect to two Bluetooth devices and seamlessly alternate between the two.” These are great HA’s, and this is one of the best features.
Since there is so much confusion with this, I documented how to connect an iPhone and iPad in this thread: Connecting an iPhone AND iPad With A Phonak Audéo P-RT [Draft Guide]. Please take a look and let me know what you think.
Best regards,
Dan.
