Hi Biggar,
Thanks for the link.
Wondering exactly what made for iPhone entails? Assuming it uses Bluetooth but will only connect to the IPhone versus next generation Bluetooth that will connect to any Bluetooth device. Does that sound right?
Do you find live listen valuable? Where is it useful?
Thanks again-Sandpiper
I am not an expert in Bluetooth, just a user who has read some available documentation. MFI is an Apple approval seal for a wide variety of stuff (including simple things like cables), one subset being hearing devices. As I understand it, MFI for hearing devices is a set of protocols running on Bluetooth Low Energy that define how to communicated with hearing devices using an iPhone/iPad/iPod. Many hearing device manufacturers have built MFI devices, Phonak being the major exception. MFI for hearing devices is not new - it has been around for a number of years. Real details of MFI appear to me to be available only to device manufacturers who sign onto a non-disclosure agreement (and probably pay a fee). Note that MFI for hearing devices has not, as far as I can tell, been included in Apple computers but only in Apple iOS/iPadOS devices meeting certain minimum version requirements.
Bluetooth 5.2 with LE audio is much newer and not really fully defined or implemented yet. It may replace MFI for Apple devices but Apple is usually fairly silent on their plans until they are about ready to release something.
I have not used Live Listen much. I have used it in a noisy cafe where I put my iPhone on the table close to people I was having trouble hearing. It helped but I haven’t found much need for it, especially during the last year
