  1. The support for the old version of FiiO Music app will be discontinued. And this new version will be updated in accordance with the standalone version (available in Google Play).
  2. The agreement of cooperation between FiiO and ViPER’s Audio has expired, so we’re afraid that the new version of FiiO Music will no longer have the embedded ViPER Effect plugin. However, we’ve been working hard on the dynamic EQ and will try our best to develop more audio effects.
    • If you have purchased the ViPER Effects and would like to continue using it, you may download the apk file of the old version, copy it to the player, and then install it through ES File Explorer (this will overwrite the new version). If you have any other questions, please kindly contact FiiO (email: support@fiio.com, Facebook: FiiOAudio).
  3. FiiO has changed the database structure of FiiO music, therefore the player will transfer data from the old database to the new one during the firmware upgrade. In order to prevent errors, the procedure will also scan the music kists during the transfer and remove the tracks that are not found in the storage. To ensure that the song lists are transferred in entirety, please remember to insert the SD cards to the respective card slots before updating the player.
