I know there are a bunch of posts on headphone cable and I have done plenty of research on the topic through this site and others. There are just a few things I have questions on that I am not 100% clear on.
First off, here is my project/plan. I got a pair of cheap Sony MDRZX100 headphones ( http://www.amazon.com/gp/product/B004WODP20/ref=oh_details_o01_s00_i00 ) off Amazon. Since this is my first attempt, I did not feel like cutting up a more expensive pair of headphones. I then bought ~10 feet of Canare L4E5C quad cable , ~5 feet of Canare L2E5 cable , one stereo plug, 2 mono plugs, and 2 mono jacks.
I plan on cutting the old cable, opening up the cans, and connecting the existing cable end to the mono jacks and mounting the mono jacks inside the cans with the jacks poking out where the old cable went into the bottoms of the cans. Then I want to take the L2E5 cable, solder up one end to the mono plugs, and I will have 2 lengths of cables with one end having a mono plug and the other free. I will take the L4E5C quad cable, solder it to the stereo plug for the other end. My only question is the connection with the open ends of the 2 L2E5 cables with the open end of L4E5C quad cable. I feel like simply soldering the wires together would not only be difficult to make look good, but could pose an issue with the audio quality. Is there some plug/connector that allows the bridging of the cables together? Or would I be better off splitting my quad cable and using the quad cable entirely?
