That's terrible. It should be normal bluetooth, but with some optional flags to say that it's a hearing aid or whatever so that it can be more specifically supported where appropriate. I guess if it's a power consumption low energy thing, it would make sense that it doesn't work with legacy bluetooth, but in that case the same low power tech should be available to non-hearing-aid bluetooth audio devices.
