I just got my hands on some Chill Pill portable speakers. I’ve been out with them few times, and for their size, they can blow it up! Perfect for the park or some on-the-go music sesh’s, these guys pack a 6-hour battery and internal wiring so your always good to-go. They collapse down small enough to fit in your pocket, and best of all they only cost 40$. Grab them here.
