A:Answer I would not suggest you buy them, mine broke after 20 weeks of use in office environment, I would expect that during a workout this will simply broke after 2 or 3 uses. Mine look new, no scratchs, never dropped them, treated them better than I treat my phone and still they didn't even last 1 year. Poor quality, no manufacturer warranty from SONY that covers for materials defects, buy BOSE instead
