- Addresses an issue where, in rare cases, sound may not be produced when the WALKMAN is connected with the digital amplifier
- Provides additional function updates
- Supports LDAC (a newly developed high resolution codec) during Bluetooth® connection.
- Improves a condition where the Walkman may be slow in action when a FLAC (Free Lossless Audio Codec) file, which has more than one jacket picture, is played and moves to the next or previous song
