    • Radio interference will affect the Bluetooth communication between the headphones and the playback device. The interference is likely to occur in a crowded place, near a store's cash registers, near a microwave, near traffic lights or automatic doors, inside a crowded train or in a station, etc. To avoid interference, move the headphones and speaker closer or set the sound quality mode to Priority on stable connection in the Sony | Sound Connect app.
    • Turn up the volume on the connected device.
