BatteryANC on: 6 hours of music from the earbuds, 26 hours with the case; ANC off: 7 hours, 30 hours with the case; earbud 53 mAh, case 515 mAh

Talk time is 4.5 / 20 hours with ANC on and 5 / 22 hours with it off. The case supports wireless charging.

Samsung		Up to 7.5 hours per charge (ANC off) / up to 7 hours (ANC on); up to 30 hours total with the case; lithium-ion, 75 mAh per earbud, 820 mAh case

Times were measured with an iPhone at medium volume (85 dB). According to Sennheiser, 8 minutes of charging gives about 1 hour of playback; the battery protect mode in the app slows charging and slightly lowers maximum capacity to extend battery lifespan.
