They may look good and sound ok but that's about it. They are extremely annoying as they keep falling out of my ears and part way off of my ears. Considering the overexagerated price of these I was certainly expecting something a lot better than this. I have bought JVC in the past, I have worn them everywhere including in bed at night and they stayed in all the time (including all night) These are terrible. I would never recommend anyone to buy these, especially for sports use. I shall be attempting to return these as, in my book, they are not fit for purpose and mis-described by the manufacturer.
