I looked into the Forerunner watches but you can't store music in the watch itself. You can only use bluetooth and stream music off your smartphone. So you'd have to run with your phone along with the watch and headphones. With the Garmin Vivoactive 3 Music watch, you can download up to 4MB of music directly onto the watch itself, which is an overkill amount of storage for music. I'll never fill it up. So I can enjoy runs with the watch and headphones and that's it! I can finally leave the phone in the car, which is a big plus for me personally.
