I swapped out a Jabra BT250V for this (see review).  The Moto is a heck of a lot better - sound quality pretty good on the calls, functions with the Moto E815 no problem - voice dialing works without a hitch, volume on the phone controls headset volume, redial function, etc.  The moto is kind of clunky feeling - you know you're wearing it but not that uncomfortable.  Just a big plastic thing hanging off the top of your ear rather than the "in the ear" school of thought.  I love my Jabra wired headset - don't know why the BT was so horrible.  Works fine in the car as long as the windows are rolled up - affected by wind noise, high background volume, etc.  But that's to be expected.  Can't comment on battery life - haven't had to charge it again yet.  Folding boom switch is great.  I turn auto answer off and just fold out the boom to turn on the headset as needed.  Overall - the range and sound quality are very acceptable.
