Description
These headphones were used briefly and then put back in the original box.
Charged yesterday and listened to music at normal volume for approx. 4:30 hours today.
Sound flawless. After 4 hours the battery indicator was at 80%.
I can't guarantee whether this is correct.
The battery should last 10 hours and it certainly will.
