More Information:
For aptX HD: Its appearance is related to the increasing popularity of high-definition audio. It can support up to 24-bit/48kHz audio, which means that we can listen to music with better sound quality with wireless devices. Compared with 352kbps for aptX, the bit rate is increased to 576kbps for aptX HD.

For aptx adaptive: It combines the advantages for aptx hd and lossless, and can adjust sound quality and delay adaptively. It aims to create a next-generation wireless audio technology that can be used across devices, suitable for smartphones, tablets, computers, headsets, gaming headsets and speakers. Provide you with the ultimate and excellent wireless listening experience.

For LDAC: It is an audio codec. It can transmit and stream 96KHz/24bit music (also known as high-resolution audio) via Bluetooth, with speeds up to 990kbps. It can transmit about 3 times the amount of information of ordinary Bluetooth audio [refers to the use of A2DP protocol, SBC encoding] (328Kbps, 44.1KHz).
