Negative Positive
Title: Keep the box handy!
Review: The ergonomics are great, the way it recharges is very advanced, BUT it just didn't work. There was a card on the unit advising to turn up the volume so it didn't auto turn off but it had in my opinion a defect that let it pop in the middle of listening. The duration was about .5 seconds which is a long time.
