yes the only thing it modifies is the 3.5mm jack so that no matter if its the video cable or the headphones going into the 3.5 mm jack it will pop up the video out on the screen of course if you are using headphones in the 3.5mm jack you can just dismiss the popup and use phone like normal to listen to music. Doing this mod does nothing to the other 2 headset jacks. They will get detected as a headset and will work accordingly.
