— support of aptX HD codec.The aptX codec was originally created to improve the quality of sound transmitted via Bluetooth. See "aptX support" for more on this. And aptX HD is an evolution of this technology that allows you to achieve even greater efficiency: the sound quality in this case is compared with Hi-Res audio (24-bit / 48kHz), and the sound purity is indistinguishable from a wired audio signal. And although these statements are sometimes questioned, aptX HD provides very high sound quality when streaming via Bluetooth. On the other hand, all the advantages of this technology become noticeable only on the same Hi-Res audio — with a quality of 24-bit / 48kHz or higher; otherwise, the quality is limited not so much by the specs of the connection as by the properties of the source files. And, of course, this codec must be supported not only by the phone, but also by external audio device.
