I opened the case and found just a poor quality mic and not even a mic hole(sealed water tight) i soldered on a 3.5mm audio jack. It can now be hooked up directly to any audio source with a headphone jack. The reaction to the music is amazing. I tried adding a audio jack to the bluetooth speaker box by simply soldering it to the 2 speaker leads of the speaker, it does work but the powered speaker doesn't like it very well once its connect to the light controller audio jack, it pulses on & off. I imagine this is due to an ohm issue. Does work if you start the mudic then plug it in
