You welcome etalton.
It does get a bit getting used to adjust the hook, but because I'm used to doing it for my hearing aids as it easily comes off as well, so it's not as bothersome.
Cochlear DO have earmold hooks. So, if you decide that you don't want extra equipment and still feel that it's not "hanging on" right. Buy the hooks, and use your old earmold, you can chop it up as much as you want as it's not needed...make it smaller or whatever. It will hold it in place better than anything else and it's great if you're skiing or doing rigorous activity (running, biking, etc etc). The only problem is I don't see it on the Product list, so I suggest you to call them.
Lmk if you want me to take a picture of them to show you the product.
