Does it have a remote control? Be cautious about headphones that have extra controls, because headphone jack configurations can differ between iPhones and Android devices, and even between some Android devices. A pair of headphones with special controls that are designed specifically for iPhones might not work fully on an Android device--you might end up having weird pauses or skips, as if the buttons were pressing. Check the package to see if it says "Designed for iPhone"--if that's the case, then full compatibility might be an issue.
