I saw this on Shark Tank recently and think this would be great for improving the audio quality of the iPad, when traveling especially. I often find myself in a hotel room wanting to watch a movie but not wanting to wear earbuds. I set my iPad on the nightstand and settle in to watch my movie with the sound cranked, but sometimes it's not enough especially for the quieter scenes in the movie. SoundBender will do the trick. I've used my hand to redirect sound at times when playing a video for friends in a noisy place and this product is like a tiny little cupped hand redirecting delicious sound right into your cochlea!
I wonder if they will ever make one for the iPhone?
