I have had The KS9/Phonak ($1,500 per pair) hearing aids since December 26, 2019. I am generally satisfied with them when used just as a hearing aid, but I have a few peripheral issues. One relates to Bluetooth use.
I use BT both for telephone and listening to books (iPhone 11 Pro) Telephone connectivity is inconsistent and unreliable. I can initiate or pick up a call via Bluetooth, but the BT connection will generally fail after a few minutes I have to put the phone to my ear (which works just fine). I thought perhaps it had something to do with interference from other devices in my residence, but I have tried it in several places in my house and the issue is about the same all over.
I use BT for other purposes (for example, connect my phone to my Apple Watch 5, connect to my car, a Subaru Forester, connect to headphones) so I pretty sure it is not the phone, but rather the hearing aides.
Any ideas about fixing this issue? Hands free connectivity is very important to me, as I need to have my hands available to type while conversing. Thanks.
