Slipper is not leather and is only fair quality for Daniel Green. Music continues to play but it has intermittent audio at the speakers Con: They are super sensitive to touch (tap) and many times have dialed my contact list or switched to voice control unprompted. Tends to be a bit more wonky with Bluetooth connectivity then my previous JBL Charge 4. They are comfortable and sound very good. Then they lost all battery life. The dark navy blue is sharp and the quality is good. Install with super easy, it is able to hold a wide variety of heavier items. Hopefully they break in soon. Very sad because these are far and away the most comfortable flip flops I have ever worn.
