I can mount them, but they dont balance nicely and are difficult for the kids to put on/off. My feet are also on the narrow/skinny side, so it is a challenge to find strappy & open toe shoes that my feet wont slip through. The old ones were still intact but because hed lived in them for around 8 months, they were pretty grody. I couldnt get it to pair as a Bluetooth headset to my phone. Super bummed! I dont know how many time I almost cried. This case is stylish and matches my iPhone case. It?s still overall a very flat, natural curve, and everything is really clear and distinct. It is of good quality but a bit too long for me. TURNED UP LOUD NO ITCHY EAR CANAL SYNDROME WHICH IS ASSOCIATED WITH JUST ABOUT EVERY OTHER EFFIN HEADPHONE BRAND I TRIED.
