| Condition | As good as new |
| 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. |
