The battery performance of these headphones is excellent. They last over 30 hours off a single charge, which is superb, and is exactly what Turtle Beach advertised. Unfortunately, they take almost 2.5 hours to charge, which isn’t that great. On the bright side, they feature an auto-off timer, though it isn’t stated how long it takes to turn the headphones off, and it seemed to turn off the headphones quite quickly during our testing.
