They fit just the ankle. This was a little hard for me and had to get a bit of help since holding the nut inside of such tiny space is not easy but also not impossible. These are generally pretty decent as I?ve ordered in the past. I used them with a cell phone , a computer, an MP3 player, and older iPad and iPhone and iPod, a video game player and a new PSP,. One pair had a broken button. Very happy with comfort and color. Things that aren?t so good about the Aonic 50?s (why they don?t get 5-stars): The music doesn?t pause automatically or reduce volume in ?Environment mode?, so renders it pretty much useless. jai lu attentivement l "User manual" dispo en toute langue, qui préconise de charger complétement avant utilisation. Installation is not difficult, but it slow for me. I read many reviews on this product before ordering 2 of them.
