Careful about that Jabra bt3030, I have one and the audio performance on those things are below standards. Now I just downloaded an app called Volume+ for my nexus to boost volume and there's a setting for adjusting bluetooth headsets which I have yet to try. Just know that those bluetooths have below standard volume.
