I love the celestial design and they are super comfortable. The only positive is that the aluminum is rigid and the price was right Revised 2nd review: This Harmony style was the second Zenz slipper Ive bought. bought this to use in a camper, in large part because I can use 12v DC to charge and power it. Both my kids can enjoy them and not worry about slipping or the sandal breaking. It made a lot more sense, but sucked if you were looking for any resolution after reading only the first book. I followed other reviews and ordered a size up, big mistake! However they do not include mounting screws like they advertise We installed this rack a few months ago. The covers/tips usually make a far, far greater difference to sound than a different model headphone, leaving features aside.
