A nice surprise for such a simple product - basically a headband fashioned with software as a headphone. It took a minute to figure out where to connect to charge (a little slit on the control panel), but once charged and paired on my iPhone (advise you put the headband on first and push top button in until you hear the pairing direction). The sound is really good! I have used them almost nightly since they were delivered a few weeks ago, and so far so good in terms of recharging without issue!
