I really love your idea to reinvent that product category and modernise it. I work in an open office and it can get really loud sometimes but headphones with music on are not always what I want, so I would really appreciate your new concept. Besides, they look cool and fancy to wear.
One question for you: Are you planning to make one version of the product or different ones for the different targets? What are your plans regarding that?
This product could also be great for travellers (business, students, etc.) who want to be undisturbed but still able to concentrate on their tasks without headphones (music) on.
