Does any one recommend a headphone splitter that works with an iPad2? The reason I am asking is that when my daughter tried to use her headphones with my new iPad the plug did not go in far enough to work. I found another pair of headphones that worked fine. It looks like the plastic housing of the plug hits the bevel of the iPad. I am needing a splitter so both my son and daughter can watch movies on a long plane ride next month.
