Yes we're wearing them inside the helmet. They usually stay put. They are, like many other earbuds now, passive sound dampening. Meaning they cut the noise down without electronics. I tried them onboard aircraft, and they really work well to kill the jet engine noise, and that's something amazing. So they kill the wind noise inside a helmet, unless you've got a loud leaky helmet or something. And the sound range is good, the bass decent. Get her some skull candy ink'd. Most people like them. If it was the type that sits on the ear instead of in the ear, get the Sony buds. Skull Candy has a no questions return policy. If you destroy them, they will send a 50% off on next purchase. I suspect you have to buy from the website, so it doesn't save as much as I think. But it's better than nothing. If the darn things just stop working, they will send new ones. I do hear that some people wait forever to never to get them, but it's worth a try.
