Qualcomm aptX Low Latency Avantree Audikast adopts aptX Low Latency technology, which ensures the sound is delivered in sync with visual media, it significantly reduces delay and brings on a high quality and synchronised user experience, especially ideal for watching TV/movies/videos. Audio delay under different codec :

Codec aptX Low Latency (aptX LL) aptX Fast Stream (FS) The most standard Bluetooth codec ( SBC) Audio delay 40ms, not detectable by human ears 130ms 40ms,not detectable by human ears 220ms Dual link codec Under Dual Link Mode (connecting with 2 headphones/receivers simultaneously), the transmission codec will be the one with longer latency, eg: If one device supports aptX LL and the other only supports aptX, then the final transmission codec will be aptX; If both headphones supports aptX LL, the final transmission codec will be aptX LL. 2.
