Ill probably contact Crocs and demand a refund as this is truly pathetic. I purchased them a while ago, and only recently tried them, so I cant return them. They are very well built. Tried in my wifes iPhone - same problem-duffTried my original earphones - no problemResearched internet - This fault is a massive problem by the amount of those with the same experience. These Birkenstock Sandals provide very comfortable support for walking and standing . Sturdy and easy to install These socks are easily a decade old! Cons:- I dunno how this isnt mentioned anywhere, but the selfie camera isnt great at all in low light conditions. Great summer walking shoes. They do need bedding in when you first get them but no different to purchasing any new footwear.
