The Short Answer

Lower-quality audio doesn't require as much bandwidth (like an audiobook recorded at 32 kilobits per second rather than 128 kbps or greater, such as we use for music).

The cell phone companies may well be sacrificing sound quality for increased redundancy (and therefore, reliability) in the packets of voice data going each way. And to be fair, even sound quality on corded phones remains underwhelming.
