These earhooks secure the Pro Pods in place, do not affect noise cancellation/mic/autoplay on ear insert and most importantly, they fit on the Pro version. This is not what I ordered and this is not what is advertised! Despite all of that, I do think they are of decent quality and a good buy for the money, and recommend them, if you are a patient person. Nothing was clunking or shaking loose, it felt solid and made me trust the machine with my entire bodyweight. I ordered these to store extra blankets and clothing my daughter has outgrown. But a perfect product once its unwrapped and mounted. Other than that, this is a great charger! I use them maybe 30 minutes about three days a week. The only tiny issue for me is I wish there were a couple pages at the end of the book for "NOTES" so that I could write down my favorite recipes. Im keeping them - it is the right size - fits like a glove.
