About the DSEE function
The DSEE function complements the high-range sound, which is often lost from compressed sound sources, in the
headset to the equivalent of CD sound quality.
Sound sources compressed by streaming playback, MP3, Bluetooth transmission codec, etc. are played with natural and
expansive sound.
The DSEE function can be set up on the "Sony | Headphones Connect" app, and is only available when connected to the
headset via Bluetooth connection.
Note
When DSEE is set to [Auto], the available operating time is reduced.
