Surprisingly long battery life
Biggest thing I don't like is that it doesn't auto-turn off after a period of not playing anything. However since the battery life has been surprisingly good it hasn't been an issue. Also like that the bluetooth portion/headphones can be removed. Very soft inside and pretty good at keeping out the light. Only other complaint is that there is velcro on the adjustable back, which gets stuck in my hair.
