    Setting the sound

    Adaptive volume control adjusts the volume of your Xperia Ear Duo according to the sounds of your environment. The Clear Phase™ function lets you enjoy more natural and clear sound quality. The Dynamic normaliser lets you hear the sound more clearly in a noisy background. You can also select whether to prioritise sound quality or playback duration, under Sound quality .

    You can change the sound settings in the Device Settings menu of the host app.

    The Prioritise playback duration option consumes less battery and allows for longer playback (SBC). The Prioritise sound quality option enhances sound quality, but shortens the playback duration since it consumes more battery (AAC).
