Smart: Tangle free earbuds!

Now here is a smart idea! It should be implemented in each and every earbud manufactured from this day forward. The design uses a zipper like configuration to attach both cables together when earbuds are not in use. Personally this would make my life easier! My earbuds seem to get tangled whenever they leave my ears, sometimes even while on my ears but thats a whole other issue! Now imagine all the free time created by this annoyance-avoiding time saver!
