For the rest, ... Using a conference call (thus using the speaker internal mic), it does not. Unable to my interlocutors to hear me (this after several tests under different conditions).
Update firmware: a galley. It was necessary that I use a PC and a Mac to get, apparently, to update the enclosure.
Finally, iPhone application side, the support I wandered on a display concern on an iPhone 6 Plus. Once they understood that they would not know how to respond, they directed me to FAQs that had nothing to do with the subject. No.
Moral: pregnant returned to Amazon and purchase of a Harman Kardon Esquire mini model. The latter is more expensive, but now at least, it was worth the money. In addition, it is more compact than the Jawbone.
I DO NOT RECOMMEND this at all Jawbone Jambox mini.
