The list of compatible phones is ridiculously small. For the price of the devices, they should be compatible with everything including a 1000 B.C. abacus. The programs tab always gets stuck in streaming mode, so you end up having to fiddle with the little switches on the hearing aid itself, so apart from volume adjustment, the app is pretty useless. Not very happy since I go from a noisy factory environment to an office a hundred times a day.
