We tightened the straps every time we stopped, but never were the straps in need of more than a tug. If I do, Ill update this review. I tried some of the in-ear only, but once I started sweating, theyd work their way out on a run, or Id have to futz with them constantly to prevent this. I feel like they were made for me =) Thank you Betsey Johnson! For the cost, I say they are definitely worth it. Works great for my Beatssolo 3. They sound really really good. My feet are a little wide and I have trouble finding shoes that feel good. These are awesome, slightly large, but overall great fitment. Im thinking Im going to have to cut my way out because Im starting to freak the duck out.
