I have no clue. But I have that bluetooth sport speaker and it's fantastic. However I'm sure it's made by a completely different supplier. Personally, I've never liked the bluetooth headphones that are the style where all the electronics are in the earbuds, and the two are just connected by a thin wire. I've tried several and the weight of the internals always pulls them out of my ear. I've had much more "luck" with the LG Tone series of headphones, though they tend to break on me.
