Ear plugs to deafen your flight

On a recent flight, I was continuously annoyed by two women sitting behind me that did not take a breath for over 2.5 hours. They not only talked continuously, but they talked so loudly that I could not drown them out with my iPod on its loudest setting. They also coughed without covering their mouths. I hated them and did every thing I could to make their flight less enjoyable.

Another flight found us sitting next to the engine (with no view at all). It was so loud that in order to not scream in pain, we had to insert earplugs.

We cannot afford noise cancelling headphones....so perhaps here is the solution:

In-ear headphones modded with swimming earplugs. Seems easy and clever as hell.
