Perfect product for my use (a home computer, mp3, smartphone), nice finish and correct price system for folding the nickel headphones! 3 stars ONLY because of the packaging! A simple envelope with bubbles and blister of the product directly into it! So I got a blister fortunately completely crushed helmet looked in good condition but still why not put in a little cardboard ??? Being myself deliveryman I know there could be tens of kilo placed upon or someone could walk on it! BRIEF VERY VERY DISAPPOINTED PACKAGE!
