Who knowsReview Update 9/16/17: I read about the new firmware so I bought them again updated to the latest firmware and no problems! I ordered a replacement, and found it to be the same deal, yellow plastic instead of clear (in addition to the pink striping on the sides), and extremely inflexible and difficult to put onto the speaker (and totally impossible to get off of the speaker--even after my husband and I both followed the directions/illustrations to do so). volume a little quiet . I was wanting a summer sandal/wedge with a bit of height. (Listen to Regulate by Warren G and Get Ready long version by Rare Earth). He wears a size 12. Will need longer screws and a better drywall anchor. Two have held up great, one broke the first week. Los controles que se encuentran al lado izquierdo facilitan la reproducción de música, como ya nos pasa con los audífonos alámbricos que cuentan con el control, pero aquellos que ya hayan usado audífonos bluetooth con control no me dejaran mentir cuando diga que el uso se vuelve más fluido, dinámico y menos engorroso. We probably couldve fit at least another smaller bag inside, but didnt chance it.
