Alice 2 The package arrived 26 days after order. I did not realize it was coming from China when I ordered it.The box was damaged, and had been opened (probably by Japanese Customs) and the rechargeable lithium ion battery that was supposed to be included was not in the package.This battery is 5V and long, and no one in stores can figure out what kind would have been used. It seems like the battery was unique to the speaker.So the speaker and headset is not useable, unless it is attached to a USB port in 'charge' mode (there is nothing to charge, but that is how it can have power).
