Just about every brand that builds something with a microchip you can buy at a big box store makes a bluetooth speaker. Just in case you haven’t figured it out yet, most of them suck. And the ones that don’t are so prohibitively expensive that you’d be insane to buy them. Then there’s the fact that it’s still bluetooth, so the range isn’t going to get any better. The entire system needs to be rethought, and that’s exactly what Rocki did with the Play system. One smartphone sized dongle that you connect to speakers, any speakers, with a standard 3.5mm cable and pipe audio to with a WiFi connection. No bluetooth range issues. No carrying around additional hardware. No taking out a second mortgage. Hell, for $49 each you could put one in every single room in your house providing they already have speakers.
