It's important to understand the distinction between protected and purchased music when downloading files to your H2O Audio device:

  • Accepted File Formats: Your device supports MP3, M4A, WMA, and APE formats. Ensure your music files are in one of these formats and are DRM-free.
  • Subscription-based Services: Music from platforms like Apple Music, Spotify, Amazon Music, iHeartRadio, and Pandora is typically protected with DRM and cannot be directly downloaded to your device, as these services offer access to music rather than ownership.
  • Direct Downloads Only: Your device accepts files that are directly downloaded and unprotected. This ensures compatibility and uninterrupted playback.

If you're unable to transfer purchased music from iTunes, consider the following:

  • Cloud-based Music: Verify if your music is stored in iCloud rather than on your device. Look for a cloud symbol with a downward arrow next to the track in iTunes.
  • Downloading from iCloud: Click the cloud symbol to download the music file to your computer's hard drive. This step is necessary before transferring music to your H2O Audio device.
  • Transferring Music: Once downloaded, you can drag and drop or copy and paste the music files into your device's memory.
  • Further Assistance: If problems persist, our customer support is available to help via chat, email, or phone.
