Audio latency and delay is something we strive to minimise as much as possible however unfortunately, this is something that cannot be eradicated altogether.
The amount of latency does vary, and is dependant on the products you are using.
There will always be a slight audio delay when viewing video content via your Yoyo (M) speakers. This is because the right channel Yoyo speaker has to decode and send the appropriate signal to the left speaker via Bluetooth.
We recommend using the Yoyo (M) speakers for music only.
