I bought 3 Beats Mini Beatbox, i want them all to play together?

Okay, firstly it says on the box of each of them, 'Modular buddy-jack design, connect multiple speakers in a row for jaw dropping sound' So somehow they can be connected, i'm not sure what that modular buddy jack design is. Anyway they work through bluetooth as well as wiring, i have an iPhone and a macbook pro, ideally i would want them all to play what i want off of my mac and have them around my room within a 5m range, how can i set up a bluetooth stream for them all to work? Please i really want this to work. Or if not any ALTERNATIVES. Please respond.

People can't hear me speaking through my mic when I make a call. However, when I record a video it records audio, FaceTime works, voice memos works, and speaker phone works. What is going on? And how can I fix it?

I've cleaned out the mic, I've reset my network settings, I've made sure it wasn't muted, I've restarted my phone… Nothing helps.
