Make sure it is Shipped and Sold by Amazon

These will be authentic if you buy from the right seller (Shipped and Sold by Amazon). Amazon will always take returns if something is wrong with the item. Please ignore other bad reviews because they don't know what they are talking about. If it is sold by Amazon directly, it is guaranteed to be authentic or get your money back with free returns.
On another note, these are apple so don't expect sony quality for the money. You get what you pay for.
