I have a pair of Shure SE530s and love them. I am a new Iphone convert (from Blackberry) and now have the ability to carry my phone and all my music on the same device. I see previous version of the add-on cable for my SE530s is no longer available. It's for sale used for about $150...annoying. I read about the Shure SE535s with their detachable cable and add-on accessory to give you a mic and controls. But this accessory is made differently. Am I missing any other mutli-driver solutions from other vendors? I've found a few other vendors, but they seem to be in a lower audio quality class (single driver vs 3-4 like the Shure). Thanks for any comments.
