What's considered copyright and not?

I want to buy apple headphones but I'm not sure if they are considered copyright or not. I bought minecraft stuff already and was selling them great until they removed it due to copyrights.

Since the headphones are shaped like the same one apple sells it seems like replicas which is against the TOS. So, I'm wondering what I can buy and what I can't buy.

Pretty much selling Anything with a brand name, meaning a registered name that owns a copyright and license and has an agreement with it's distributors to control the pricing and distribution of their products is something you can't sell. Look at everything like a percentage of risk. The lower the percentage of risk, the easier it is to sell these items. For example, I could go on eBay and sell Dawn Dish Soap all day because there isn't much of a risk associated with Dawn, there hasn't been anyone on there selling fake dish soap and thus eBay doesn't associate the keywords "Dawn Dish" with fraud or VeRO. With words like "Apple" "Nike" "Samsung" "Dr. Dre Beats" are highly associated with VeRO complaint products, and thus they are high risk keywords.

So personally, I wouldn't sell Anything with Apple as a keyword. Even if your product is legitimate, or not, you can still have a lot of issues.
