20 plus hour battery life, check. But before leaving the porcelain throne I ordered a new set of the same exact ones! Schade, dass ich das erst gemessen habe, als ich andere USB-Dosen schon gekauft hatte. They delivered shiny and low quality plastic case. My current shoe rack was open and slanted and most of the shoes would fall off if bumped. I have nerve problems on the ball of my right foot and these shoes are the only ones I can wear and go for long walks in without any pain! It filters and reduces most sound really well and helps me to get immersed into whatever I?m watching or listening to. It is so true that they mold to your feet. My fav house shoes I?ve ever had! There are some positives.
