If Apple follows the same plan as past iPhone events, the 2018 iPhones will be announced in less than two weeks. 

Every day more rumors about the next iPhone seem to pop up. One surfaced Tuesday about AirPlay 2, which lets you stream music from your iPhone, iPad and Mac wirelessly to multiple speakers. Turns out, if you have an old Airport Express base station you can upgrade it to the new wireless audio standard essentially turning into an AirPlay 2 dongle for your speakers.
