Headphones shipped without padding?

I I bought a pair of headphone from amazon. They shipped in a box with no padding, just a bag of candy next to it. The shipping carton wrapped tightly around the headphone box so there was no jostling but any shock would be transmitted through. I told amazon this. They shipped a second pair but this one came in a thin bubble envelope, also not adequately packed. The items "look" ok but what I'm afraid of is hidden damage, that something will show up a few months from now. Which of these would you keep? Thanks!
