So, having this feature is nice. I knew I liked this case, because Id bought exactly the same thing in 2016 (still going strong). My battery life has been 2 weeks until I have to recharge them. I currently use the pink Beats Solo that are the photo and this review is for the black Beats, his. Besides, REI was not providing installs at the time due to CV-19. This was ok and would work easily for a road bike or one with skinny tires. I paid full price for them! Did some googling and realized that I was supposed to have an AC charger for this speaker, but it wasnt in the box. Very similar to other slippers on Amazon but for a better price and fit better. These gorgeous slippers are very pretty and seem to be very well made.
