Pop the earbuds back in and the music starts again. Smarter talking, smarter listening As soon as you speak to someone, Speak-to-Chat automatically pauses the music and lets in ambient sound so you can conduct a conversation ? handy if you want to keep your headphones on, or if your hands are full.
