Query: Volume Issues

I love everything about these headphones except the volume. I bought them with the express intent to pair them with my Casio GzOne phone to play music while I work out at the gym or while running. The volume at it's maximum setting (with the phone's volume up all the way), is not loud enough to overcome background noise comfortably. For just sitting around listening to music at home, they are great. They were easy to pair with the phone. The range is great. They are even comfortable to wear. BUT, the volume stinks!!!
