I have been having problems with crackling on music via BT headphones.
All my music on my PC is wma which isn't supported so I had used a converter to mp3.
Now, for some reason this had led to this crackling artefact.
I have listened to some other mp3's on the watch and they are fine!
I don't know why these converted mp3s are causing an issue - I used them on a previous watch (TomTom) with no problems.
I need to find some other way of converting my wma files to mp3 or other format.
What formats does the watch recognise?
