I am planning to develop a wireless device that could help more than 4 people to watch a movie in public together at a time without disturbing others…even though it is introduced in the new iphone but it is not affordable..i need the device to be commonly used like our earphones..Need Suggestions on this!!

Actually i came across this idea when i was once traveling in train..i saw some of my seniors watching a video in a phone. It was not clear as i was standing little bit away from them.Even though it was not clear for me i was looking at their expressions and suddenly i noticed that a family sitting beside them were getting irritated with the sound.I wasn’t feeling good about this because both were correct on their sides.And at that time I thought of introducing such a device….

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
