Your video player “can” account for latency if you configure it correctly which I imagine the majority of people don’t do.

Windows and Android do this automatically out of the box, don’t know about other platforms.

Ditto with your music playback always lagging 1-2 seconds behind your control inputs.

Since music isn’t an interactive medium, this doesn’t really matter

It also matters for music production, and makes life a lot more pleasant for audio/video editing

Well of course, if you’re doing that A) you’re probably not on a phone if you take it seriously and B) this is not an application for wireless audio solutions so…uh…duh? 😅
