if that and it feels kind of sloppy to me. I have to first preface this with that Im a very big fan of Sennheiser products. Just a heads up. You can run up and down the stairs without worrying about them flying off your feet. These are great shoes - I had them in my cart for the longest time before actually biting the bullet and ordering. then put them back on the charger and throw the case in my bag. Cannot comment on the durability yet. Initial pairing was a breeze and they automatically connect to one another and to my iphone upon taking them out of the case. Love this more than I thought I would. It looks like they are attached with double sided tape.
