However, without the technology that companies like Sony have patented, the solution is to divide up the audio stream so that some of it is used for audio out and some for audio in. This process lowers the sound quality of the stream when in HSP/HFP mode, so audio may be "tinny," compressed (lower-fidelity), or at a lower volume.
