You can stick with default settings or change them to your liking, for example, putting Ambient Sound levels up when you're walking to hear the world around you.

Don't miss out on your favourite sounds, no matter where you are. Adaptive Sound Control can cancel external noise, while also letting in voices so you don’t miss important announcements, for example, on your daily commute.

You can also use "Focus on Voice" to enhance voices and suppress noise for chatting without removing your headphones. To do this, simply highlight the “Focus on Voice” check box.
Your headphones also feature a wind noise reduction structure that automatically reduces wind noise from your voice during phone calls and when playing music with Noise Cancelling/Ambient Sound Mode.
