I thought that this would be good for wired headphones on the newer iPhone that doesnt; have an audio plug (Dang Apple--bad decision). I made sure to wipe the wall down with an alcohol wipe, let it dry, then stuck the hook on with a lot of pressure for about 2 minutes. The large zippered compartment is roomy enough for snacks, shorts,tshirt, hat, etc. The two prongs are angled upward so objects dont slide off. All was ok, except I received 2 pair on different dates do not know why. So this is a multi- product review. I have limited space but it fits right in, without looking cluttered. My old $40 LG neckband that I replaced due to battery wearing out after 5 years of use has a better mic and sounds just as good. Nothing ever made then go away. I?m afraid these are not narrow at all and rather wide.
