I had the shoes for a few weeks and everything from walking on the treadmill to my everyday work of up and down stairs they fill the bill in every case. extremely comfortable and responsive. Those feel good to me, and this earfun free pro also fits the bill. My daughter does not wear them that much and there are rips in them. It has 3 with 1 of them being on the front. I just want something that works. This product did not have ?fragrance? listed in the picture yet when I received the product, the ingredients are completely different and fragrance is listed. I just couldnt figure out how to shrink my feet so they would fit. Lesson learned & buyer beware. E935 is easily, no questions, the better mic.
