Loving the V10..... Quick question

[doublestack1]

Coming from a iPhone 6s+ and think the V10 beats it hands down in voice quality, easy of use and of course, customization. One thing I haven't figured out yet is how do I set the phone to cut off music when the phone rings (while wearing headphones / wired and Bluetooth)? My iPhone would fade out music being played on any app (Spotify, iTunes, Pandora, etc). Thanks
