Startup Idea : Headphone Cable Protector

It´s a little piece of plastic to hold the input of your headphones on cellphones. Example: When you are listening to music on your cellphone you may be walking on the street going to your job or home or even anywhere, everytime you move your cellphone in your pocket make some movement that will make the output of the headphone scratch inside the pocket. Some time after this action happening will make your headphone probably stop working properly, lose some chanel or even be broken, also your headphone can by accident be pushed up and make your cellphone fall on the floor when it unplug. So if were created a mini piece that makes the output protected and also fix the cellphone to the input more harder the both problems would be solved.
