Amazing bluetooth speaker. great value, volume, bass and quality. Perfect for the casual bluetooth user. Had to take away one star though: AUX in has major latency. You would think direct line-in would be lag free but, I found out many of these bluetooth speakers use DSP which causes latency, so its unusable if you plan to try a portable DJ setup. Hopefully this will be addressed in future products.
I would suggest looking for a Bluetooth portable speaker with a microphone input IF you're looking for a portable DJ setup. Speakers with a mic-in need to be lag free for them to work. Monster is currently selling a decent 60w speaker at respectable price.
