Hi i am using Westone 4 earphone. http://www.westonemusicproducts.com/catalog/westone-4-quad-driver-earphone, i tried to connect the cable into the iphone while using Deff Cleave Bumper, but it couldn't go in at all, the hole for the cable around the cleave is too small. does anybody know which bumper is recommended?? the cable is not straight up, its turns 45 degree. you could see it in the image from the link.
