128 kbps When using alkaline battery: Approx. 15 hours
64 kbps mono When using alkaline battery: Approx. 15 hours
8 kbps mono When using alkaline battery: Approx. 24 hours
  • The battery life figures shown here were determined using an Olympus test method (When [LED] is set to [Off]). Actual battery life figures will vary greatly according to the battery used and usage conditions (Changing the playback speed, or using the [Noise Cancel] and [Voice Filter] functions may affect the battery life).
  • Battery life will be shorter when using a microSD card.
