The Beats Pill is a small, portable Bluetooth speaker from the Beats by Dre line of products produced by Beats Electronics LLC. It features direct audio and Bluetooth connectivity as well as an internal microphone to conduct phone calls. This device is fairly capable of being repaired due to its intuitive construction.
My best bet would be to buy a broken Pill (make sure it isn't the speakers that are broken) and salvage the speakers from it for your speakers. The best place to do so is probably eBay. This link will take you to our replacement guide for the speakers.
