I’ve used the ConnectClip on my laptop, which works fine, but if there’s a phone call or if I start playing a video or song on my iPhone, then the iPhone connection takes priority and takes over the connection. But after I stop playing the song or video or phone call on my iPhone, then after maybe 5 seconds, the connection through the ConnectClip on my laptop is automatically resumed without me having to do anything.
But if you’re using the ConnectClip to your laptop and you don’t want to be interrupted by a phone call on your iPhone, then you’d need to turn off the Bluetooth on your iPhone to disconnect it from your HAs for sure. So basically the HAs are connected to the iPhone via MFI (with BT enabled), while is also connected through the ConnectClip to your laptop. The MFI connection to your HAs has priority over the ConnectClip connection to your HAs.
And @cvkemp is right, turning on/off between the iPhone and iPad so that it connects to the device you want is an iOS MFI limitation. There’s really not much Oticon can do about it.
And again, @cvkemp is also right that trying to compare how Oticon does the MFI and ASHA and standard legacy BT to how Phonak does it is to compare apples to oranges. Phonak decided to design the Sword chip to be able keep all their connections in the standard legacy BT land but still managing to avoid burning up their hearing aids’ battery quickly. This simplifies their connection to a single and standard legacy BT protocol that works with everything. So they don’t need to work with MFI and/or ASHA and are not subjected to the limitations of MFI and/or ASHA.
Phonak is the only company that went this route with their Sword chip to enable standard legacy BT connection without significant energy draw from the battery. All other HA mfgs (Oticon included) went the other route, using MFI and ASHA, and intermediary streaming devices for standard BT connection. So it’s not just Oticon, but everybody except Phonak is going to be stuck with the limitations of MFI and ASHA, and require intermediary streaming devices for standard legacy BT.
If simple BT connection is of the highest priority in your search for hearing aids, then Phonak should have been your brand of choice.
