With a 10-minute charge, the earphones play music back continuously for 2.2 hours with ANC mode off. The charging case provides an additional 4.3 hours of battery life for the earphones (buds and case total 6.5 hours). With ANC mode on, the earphones play music back continuously for 1.6 hours, and the charging case provides an additional 2.7 hours of battery life for the earphones (buds and case total 4.3 hours). Test conditions: Music playback in AAC mode at 50% volume. Charging and battery tests are based on experiments conducted by Nothing (at a temperature of 25°C or 77°F). Actual battery life is influenced by factors such as volume, frequency, output source, environmental interference, product features and user habits. Actual experience will depend on individual usage.
