So happy with very fast delivery. Got it over a week earlier than the noted delivery date. Got the updated version of Anker soundcore 2. This was a big surprise to my delight. Better waterproofing (IPX7 rated-was IPX5) and crisp & clear sound clarity with NO distortion at any volume with excellent bass levels. Lovin' the 24 hour playtime. Lasts me 4 shifts at work while driving the bus. I'm Wrapped!!!
