After listening for only a couple hours starting with a full charge, it was already 3/4 drained. Overall, I am still very pleased. They were either going to rip apart or not fit. Makes it feel super cheap for such a pricey headset - Adjustable up and down in the vertical axis. This was a very cute shoe that I bought for my daughter. A win all around! Runs very unstable. Just dont be an idiot. Its possible to use them even if they run large on you.
