I ran three times with Jabra connected to iPhone 6. Sound is great, Especially For Wireless earphones! I Had to put volume is 40% so I can hear outside noise (vans). The MOST importantly is to find wright Eargels and "earwings" for best fit and best heart rate monitoring.
Battery is pretty good, 4.5 - 5 hours.
It works well with Runtastic, Edmondo, Deezer, Spotify and Jabra implementation is not bad.
The only thing I could not find is connectivity with smartwatches (Android Wear) ...
Conclusion: if you can AFFORD earphones for running for around 200 I would say go for it.
