The clip is a nice feature and my husband uses it to hook his AirPods to his work bag, which helps him keep track of them. Gosh I really wanted to like these. But when working outdoors, both the round -style and the teardrop shaped ones were insecure, and I discovered Id have to stop often and press them more firmly in my ears. Theres nothing I dont like about these slippers. I also listen to a piano performance record where there is a known coin drop and it is loud and clear with this set. You know youve fallen into this trap before. No slip on the bar at all. Quite the investment at such a great price. This is a result of constant contact with body oils (this is why my dads pair is still soft). Contacted Thule to see what response I get.
