Let me start by saying that one pet peeve I have on headsets for the cell phone is when you cannot hear yourself..however..while the Jabra Evolve 65 does not play back your own voice, I actually get along quite nicely with this setup. I can use the USB wireless connection to jack into my laptop or desktop and listen to audio there, while a call comes in it switches to phone and picks up. THIS is so important! As an IT consultant I need fast switching. Haven't had any issues with battery life. Today (3/5/2018) I found that using the included orange USB Cable to connect and charge to my computer, it also funneled the sound through the headset--so charging AND using it, AND still bluetooth'd into my phones.
Currently listening to Periphery on my iPhone over bluetooth and also connected to my Pixel (work phone). If I mess with the pixel phone, the audio will cut over to Pixel--which is what I want.
