Total Battery Life With Case
Charging Case Battery Life is the rated total earbud playback time including additional charges supplied by the charging case.
The total combines listening from a charged pair of earbuds with later listening after the case recharges them. It is not the uninterrupted playing time from a single earbud charge. The earbuds must normally spend time in the case between those listening periods.

Compare totals under similar test conditions, including volume, noise cancellation, connection mode and call use. A figure measured with ANC off may not describe everyday listening with it enabled. Battery age, temperature and usage can also change the available time.
Check the earbuds’ single-charge duration separately, together with charging time and any quick-charge claim. Do not add the single-charge figure again if the stated total already includes it. A large combined total describes stored energy available across recharges; it does not guarantee a longer continuous session or faster charging.
