I can make calls, talk to the other person, hear the other person. I can here music through the speakers. As well as in setting>>sounds, I can hear the text message tone "tri-tone" if I hit it to show that I choose that tone as the tone I want for my text messages. The same thing goes for the actual cell phone ring, I can hear it when I choose it. However, when someone calls, text messages, or e-mails there is no tone or music. And yes the volume is all the way.
