They are comfortable and even tho they looked a little goofy the reviews I read made me want to purchase because of not having tired feet at the end of the day. The sound does go louder by 1 lvl of when you change the lvl on your phone ($300+ for the quality of $30 Iphone earphones). and these should last a bit longer than the Classic Slide sandal which I also own. Fully recommend! I have owned a lot of ear buds. So far my warranty claim through CROCS has been moving in a sloth-like manner. I came from the Astro a40 TR set and although they did not sound bad, they do not compare to the ad700xs. première utilisation, aucun soucis de connexion. I contacted the seller of the Wald(not this seller) and they responded they would send me a ups label for 9$ but needed me to get a money order. Came in looking absolutely brand new in a refurbished Amazon box.
