For what they are, I have a fairly decent set of inner ear ear-buds that I use when flying. They work great on my iPhone but when I tried them on my iPad, even at full volume, I can't get enough volume to watch a movie with them when on the plane. What's the deal? Is it my iPad or just something that is sad but typical with them. Again, they work great and are VERY loud on my 3Gs. Thoughts apprecited.
