A:AnswerIt's not intended for phone use. It's a music speaker. Has no microphone and is therefore not voice activated. You might be thinking of the one Amazon sells, the Alexa.
A:AnswerIn my owner's manual I saw no indication that you can pair with other speakers or "daisy chain", nor did I see that it could in many reviews I read before purchasing the Charge2+. I have never tried it. I do know the UE Boom has that ability, but I don't think it sounds as good as the Charge2+. I think you would be happy with the Charge2+, it's a great speaker, but if you want better soundstage and detail, try the Bose Soundlink Mini ll. I ended up taking my Charge back and keeping the Bose. I had purchased both. For $50 less though, the Charge2+ is hard to beat.
A:AnswerI also have a teal one, but my friend has a red one and another one of my friends have a black one. they all come with that color cord. So don't be alarmed. Lol
A:AnswerYes, the Charge 2 has an output (USB) port to allow connecting your phone or mp3 player. This allows the Charge 2 to charge your other device while playing music.
A:AnswerI give it about 35 feet before it struggles with connection. Also, I find it does fine even if your Bluetooth source is in the next room over from this speaker.
