I use headphones a lot throughout the day, and I have some design suggestions that could lead to a revolutionary product:

1. The part that rests on the head can cause hair loss, especially if the headphones are heavy. My suggestion is to design headphones that only rest on the ears. This way, the weight of the headphones can be reduced since the part that goes over the head is eliminated.

2. I have oily hair, which means I often have to clean my headphones when they get greasy. I propose that the headphones come with a removable cover or "clothing." When using the headphones, we can put this cover on. When it gets greasy, we can simply wash the cover with soap.

3. The cables of the headphones are not springy, which means they can get stretched and damaged if we’re not careful. I suggest adding a spring-like feature to the cables.
