Its annoying because I couldnt figure it out. usefull ! Great sandals at a decent price. Will be a great gift. Das Koppeln der Kopfhörer mit dem Handy ist ziemlich einfach. After opening, I was like, "these feel pretty cool! Sending both back tomorrow. Seems like it could be a quality product if the screws are tightened properly. They are really lightweight and a lot less bulky compared to many others on the market. Thank you for great customer service.
