    Thats HD Voice over HSPA+ (4G). VoLTE hasn't been enabled for the 5s at the moment, which can change at any time. HD Voice over HSPA+ uses 12.65kbps. If you get a phone that can call using LTE, that increases to 23.85kbps, so its even better when you call LTE to LTE.

    FaceTime Audio uses AAC-ELD codec for "full HD" audio experience, etc, and even though audio quality is very subjective, AMR-WB (which is created for speech) isn't going to sound as good as FaceTime Audio, assuming sufficient data connection.
    The main user benefit is QoS dictated by the wireless operator, and better call quality when compared to traditional voice calls.
