If you turn noise canceling off those numbers go up to 12 hours for the earbuds with 24 additional hours off the charging case, for 36 hours total! But the company is quick to note that performance will vary based on settings, environment, storage, usage, and that over time the capacity of the battery will degrade so Sony does not guarantee these numbers, but the point is that you do get a long playtime out of even a single charge, despite the diminutive size, more than enough for example to cover transcontinental flight.
