Maybe it’s five? I just know that sometimes I wear them nonstop starting from when I come back from lunch and they die a bit before I leave; if I haven’t taken a break and charged them for a few minutes.

I’ve also had them since launch and use them basically every single day at work. Maybe those ridiculously tiny batteries have worn down a little bit.

I thought their case charged them quickly? (I use giant beats headphones to make me look cool ;) they ostensibly have 40 hours, but take quite a bit longer to charge)
