In another thread I spoke about the Bose on-ear headphones that fit any iphone case. However, Bose sells replacement and extensions cables that could be used to fit any 3rd part headset to any iPhone case...since the male plug is the same size as the Apple OEM. Certainly the 20 foot female to male cable can be used with any oversized 1/8" 3rd party headset...since the male plug fits all iPhone cases that I've tried. Bose extension cables Only $13. Alternatively the replacement 54" cable can be used, but one will need to pick up a male to female adapter like this one. Can't be certain that the mic/ipod controls will pass through though. Amazon 6 foot male to female RadioShack 6 ft maybe some effort will find a shorter one less than 6 foot. Just a thought!
