Really great comfortable shoes but lack of quality in general. I wear these slippers every day and I absolutely love them. I will say the grip on the bottom of these sandals are fantastic just shame the sizing wasn?t good for me. The bag has velcro on the back, so it sticks to the case & doesnt move around. Great sound and quality is overall very good, my only problem is that after an hour or so I found them to become increasingly more uncomfortable, fitting tightly and the large ear pieces seemed to heat up and made me very warm. They won?t even return your email about your free item! Save yourself the $20 and just buy the ST4000DM004. For fans, this is the culmination of a 12-year wait and its a no-brainer. At first they were all working. This is very good for those staying in a studio type condo.
