It connects over Bluetooth 5.3 and iClever quotes up to 60 hours with the lights off, or 20 hours with them on. A 10-minute charge gives over 7 hours. The included 3.5 mm cable lets it work wired too, and the built-in mic handles online lessons and calls. It folds for the school bag, and a sticker sheet comes in the box.\u003c\/p\u003e\n\u003ch2\u003eKey features\u003c\/h2\u003e\n\u003ch3\u003eTwo switchable volume limits\u003c\/h3\u003e\u003cp\u003eThe headphones default to an 85 dB limit.
