Your rentals arrive to you fully charged. You won’t need to recharge the headphone batteries unless your party is longer than ten hours.
However, we do include a battery charger for multiple headsets when we send them to you.
You plug the charger into the wall, connect the charger cord and plug in the headphone. It will glow red while it is charging and green when it is done.
