i don't know. i think it's pretty clever actually. Now if only someone would buy me two for xmas...
and i suspect it charges while levitating. The amount of current you'd need to create the magnetic field would be significant enough to charge it as well.
Initially impressed, then sorely disappointed when I checked their site. it's not much more than bluetooth, battery powered omni-directional speaker mounted on levitating magnetic base. around 2-3" worth of MONO speaker at that.
I was hoping for more impressive piece of speaker technology. Can't imagine it sounding significantly better than regular $50 bluetooth speakers.
in fact, I wonder if the levitating base actually be detrimental to energy efficiency/low frequency response due to 'flexible' nature of the speaker basket that floats in mid air.
I was hoping it would levitate a little higher than that and not have such an obvious base, but that would take a lot of power and probably screw with the speakers inside. It's a cool idea, but it doesn't seem worth $179. Maybe $50. You can get these really cheap on Amazon, and then it couldn't cost much to put a speaker in it.
