I just got my headphones. They worked for phone calls (with some static), but I couldn't play music through them. The buttons work as far as pausing and skipping songs, but no music through the headphones. I contacted Jabra and found out it isn't compatible with the Curve. Would've been nice to know ahead of time. These are a little expensive to be just a remote control for my phone's music player.Check the Jabra website before purchasing to make sure they are compatible. Just because your phone supports advanced audio doesn't mean these will work with it.
