‘Muffled, cheap boombox’ Posted on Tuesday, October 9th, 2012 at 10:06 am. PTWritten by Jim Dalrymple Shawn Blanc in his review of the Hidden Radio, a project he backed on Kickstarter. DT Shame, I recall that project, loved the design aesthetic. Sounds like they need some kind of ball bearing assembly to make it turn freely[?]We scored a SuperTooth Disco, another outstanding portable BT speaker. It’s bigger than the Jambox, but has richer sound, smoother mid/lows (like a better crossover), also reverse controls the device and lasts a long time on a single charge.
