Better than average arch support. Ill assume they will last well as Tevas are typically durable, but Ill update this review after a while if that isnt the case. The mic button works, and so does the volume. No tiene gran sonido pero lo uso para conferencias y muy bien. She?s had them for over a month. Very happy with them and they actually do look cute, too. I tried these in multiple controllers with the same results. I was informed that they no longer sell the item with that accessory but they were incredibly accommodating and took amazing care of the situation. i will go to make a call for work and only the right ear bud will have any sound. This size 12M is snug, but I have no fear of my feet coming out of them.
