CHARGING
Before the first time use, make sure to fully charge
ZeBuds inside their charging box with the USB-C
cable for about 2 hours.
ZeBuds and its charging case will reach maximum
battery capacity in order to provide you with up to 12
hours playtime.
ZeBuds can deliver about 3 hours of battery life. When
reaching low battery level, you will hear an audio
indication in your earbuds inviting you to put them
back in the charging case to recharge them.
It will take about 90 minutes to fully charge your
earbuds in the charging case. Once the charging case
is fully charged, you can recharge your earbuds up to
3 times until it reaches low battery.
