Volume set to playback loudness of 75dB, 3-band EQ set, to zero in Quiet Mode (full noise cancellation). With Immersive Audio off, playback time was up to 6 hours before battery depletion. With Immersive Audio on, playback time was up to 4 hours before battery depletion. Battery life varies based on settings and usage.
