Question about Creative outlier pro headphones

We were able to gather the following data from the supplier: "...providing 60 hours of total playback up to 15 hours on a single charge, listen without worry. With ANC or ambient mode enabled, Creative Outlier Pro is also capable of providing up to 40 hours of playback at 10 hours per charge. When the battery finally runs low, charge the case with the included USB-C cable or leave it on any Qi-certified wireless charging cradle...".
