Title: Poor instructions, risk damaging equipment
Review: I purchased the Coby adapter because it was suggested to go with the folding Panasonic speakers that I also bought. The instructions where not clear, and I take any electronics classes in grade school so I know nothing of polarity. I took the one tip that fit into the speakers, flipped the switch to the suggested setting, and I got nothing but buzzing. I feared that I would be damaging the speakers, so I packed it up and returned it to Amazon. I trust that I will be refunded.
