Sony has today released a firmware update to support High-Resolution streaming on its NW-ZX500 series and NW-A100 series Walkman® at 192 kHz / 32-bit. A highly anticipated update which was first shared in my review of the Sony NW-ZX507 Walkman® in April.

Sony NW-ZX507 Walkman

Prior to the update, contents from streaming services such as Amazon Music HD, Apple Music, Spotify, and Tidal are down-scaled to 48 kHz / 16-bit. With the firmware update, the output is now at 192 kHz / 32-bit, even if the original resolution is lower than 192 kHz / 32-bit.

The pre-installed Sony W.Music Player is also updated to version 1.10, enhancing three functionalities. These include a keyword search function where one could search for songs that match the keyword from the song / album / artist, favourites and bookmarks screen can now be accessed by swiping to the left of the playback screen as well as allowing one to have up to 999 bookmarks, a significant increase from the 10 bookmarks supported previously.

Users of Sony NW-ZX500 series and NW-A100 series Walkman® can update to the latest firmware via Wi-Fi (Wireless LAN) starting from today.

  1. i just downloaded the update but Amazon music still says my device capability is 48khz/24-bit. Is there something else I need to do?

    • Hi Dale, yes, you have to enable it in the settings.

      1. Swipe the Home screen upwards.

      2. Tap the menu items in the following order.
      [Settings] - [Sound] - [High-Res streaming].

      3. Tap the switch to turn on the [High-Res streaming] function.

      Music streamed using apps other than “Music player” is played in the following quality.
      [Use High-Res streaming] is on:
      Up-converted playback at 192 kHz/32 bit
      [Use High-Res streaming] is off:
      Down-converted playback at 48 kHz/16 bit

      Hope this helps.
