Music doesn't resume playing after using the Speak-to-chat function on the WH-1000XM4 headphones
The headphones pause or mute the music when the Speak-to-Chat detects your voice, then restarts the music in about 30 seconds after you finish talking. You can shorten or lengthen this setting in the Sony | Headphones Connect app.
Note: The Speak-to-Chat may not work correctly with some smartphones or apps.
