I have the V-Moda Vibe Duos, which I had been using with my first generation iPhone. They worked great until I upgraded to the 3GS. Now, they sometimes work correctly, but other times give me issues with the button. Every so often, when I double click the button to skip a track, it activates the voice command. It will also sometimes recognize the double click as a single click and will pause my music. There have been a few times where it will not recognize a single click at all and will just keep playing my music after I've told it to pause. Typically, stopping the song and unplugging/plugging them back in will fix it. It's just getting annoying though. Is anyone else experiencing these issues? Any ideas on how to fix it or if I should contact V-Moda? Thanks! PS - I just remembered another issue. It's only done this a couple of times, but it will sometimes cut out all music for about 1 second and then continue, almost like it has a bad connection. The earbuds/cable are in perfect condition, so I have no idea why it's doing this.
