scratch button on the right side of the headphone, it can make scratch sounds from the headphone.

I haven't seen this idea at anywhere yet.

we can be adding digital computer chip with scratch sounds to this headphone and scratch the button on the right side of the headphone manually.


this idea can make over hundreds of millions of dollars from this new design for music lover! it can be the next generation headphone.

I work with Davison invention company; they want $ 12,000 to selling this in the market from USA to worldwide!


I would like a $ 150,000 dollar for the patent and 25% profit
