My iPhone 6 was the "host" and my iPad Air and wifes iPhone 6+ were the "clients". We had a pretty good jam playing. The slight delay between the three units provided a nice "surround" effect. With the Brookstone Big Blue Bluetooth speaker I already own, along with a nice pair of M-Audio Monitor speakers that can capably handle my casual listening needs, AmpMe is more of a novelty, than a casual or even serious "party machine". Have fun, though!
