I've had one for about 6 months. Updating the firmware and pairing the device was kind of a pain when I first got it. However the performance is awesome for the price. The best feature is that you can slide the sub under your couch for Movie Theater style shaking during movies.
I don't see wires in the product image and I don't read about wires on the specs, either... but I doubt this is wireless, so what gives?
I'm sick up-to-here of wires cluttering up my entertainment zone, so let's get some bluetooth stuff here, kids!
