gg4gforme Inorder for it to be listed as USB MP3 FM RADIO, to mention USB, it would require an USB player. It also would have to have a MP3 player, to play MP3 formats. It also mentions a FM Radio, which suggests it also has a FM Radio player. I hope this helps. I would imagine, the remote would control something with electronics inside...possibly the player itself. Speakers are just coiled wire, magnets, paper, and metal...typically no electronic components, the remote would have no effect on those items.
