Customer service is slow and didnt provide good info overall. Im excited tho. It performs and functions more or less exactly the same, but no longer has the in-line volume control. Overall it is a wonderful product and I can do many different exercises although you do need to be a little bit creative it can be done The price in Canada was more than in the US. Literally can wear these for hours without getting any sore spots. Fell apart the first day. I switch cases often . This item is perfect! They are Crocs.
