Most users do not experience problems with latency, however if you do it can be down to a number of factors.
Latency is dependent on audio Codec data transmission.
The wireless audio connection creates a slight delay from when audio is played on the device until the audio reaches your speaker. This delay becomes noticeable when playing audio that is part of a video. This is similar to many Bluetooth® speakers and headsets, which means that you may sometimes experience small latency between the video and sound.
Try a different app.
If the issue only occurs with a particular app, it is likely related to the app or app settings.
