I read a bunch of threads here regarding an adaptor, but it seems that there was not a good consensus. I recently purchased a replacement cable for my Sennheiser HD-25 1 II's and it came terminated with a 1/4" male plug. I need to occasionally attach it to an iPhone 5 that has a 1/8" mini plug receptacle. I'm looking for a decent cable that has a 1/4" female end connected by 4-6" of cable (for strain relief) and terminating in a super slim 1/8" mini plug (to be compatible with my iPhone and case - super narrow clearance for the plug and sheathing). The attached picture gives an idea of the mini plug-type I am looking for. What are people using? I don't want to break the bank on this either - I've seen some offerings from ALO Audio and Qables that are way above reach.
