You wont find a better pair for the price being offered here. I got it on January 3rd and was blown away by it. I install my roof basket and follow the instructions that came with the lock cores. Personal rant, feel free to skip: Unlike many reviewers, I DID NOT get these free or for any kind of discount. Glad I brought it Stop cutting corners, is very frustrating to receive the so call Bose stands and don?t have the quality as the speakers. The translation totally likes a joke. Im sooo unhappy with this large $ amount purchase. If you?re looking to buy a pair of these slippers instead of the Fluff Yeahs by Ugg go for it! This unit uses a micro USB with a 90 degree bend on the micro side (where it attaches to the Siren X - this is due to the tight clearance between the bottom of the unit where the cord plugs into and the base) and a straight connector on the normal USB side.
