There are a wide variety of smart cases available, I picked this one cause it looks compact and nice design. The lighting portion was a big sell for me because I wanted it to match my Red AMD themed Rig. Runtime seems to be around the ten hour mark between charges, which then takes three hours or so. Oh I dont think so. So my review if you care. I had just purchased my Galaxy buds and received them a couple days before I ordered and received this case. This was such a comfortable shoe and light sandal. These worked perfectly with my kids Beats If it was slightly shorter, possibly one more hole position shorter, my Sugino crank-arms possibly would no longer hit the adjustable leg (the part you would move, to size properly. The mic is pretty good but nothing amazing, much clearer than the expensive Sony Gold Wireless headset.
