La verdad los sentí muy apretados y los devolví. These earbuds fit asymmetrically. I just love Skechers! UPDATE: I got the 11/12, and the left one fits fine. I would recommend this for AirPods Pro cases. Did not fit the size bike it states it does. If I had more stuff to hang up I would buy another. When you first start wearing them, the fur that is used is very slippery, with and without socks. - FitBoth earbuds fit my ears fine out of the box and they provide fantastic noise isolation that I can barely hear anything else but music in my noisy office. The only drawback is the shaker inside lid doesnt stay on too well.
