I also had a JBL Onyx 5 and this is louder and the Onyx only has mono speaker (it does a good job of faking stereo though) this clearly beats that. The instructions were a little odd but pretty obvious how to use it, have to use the shiny side toward the tire (so they say) so it wont melt in hot weather. ) and am glad I did. Made of foam, I thought it looked cheap Just a bit of a pain to change out belts when I want to. The band in the middle also rolls up, which ends up being incredibly painful. They WILL keep your feet toasty warm tho! Talking quality was very good. It?s a bit short, and could use more space or baskets And the new one will not charge if you use it.
