I did notice that my ears get hotter with the PXC 550 as compared to the other models mentioned above. The feet seem. My goto summer sandal. The pad is so easy to just lay your phone down on and rest good knowing your phone will be charged in a jiffy! These were very sparkly and the color was exactly as expected. Great replacement for the original one I lost. Also have her do some type of athletic activity. I haven?t worn these out yet but I will update y?all on the wear. I like the way these fit. Sound comes in great still too.
