This particular cable has a 4.4mm CuTECH, gold-plated copper plug, and 2-pin copper IEM plugs at the headphone end. The cable works just ducky, it just wasn't quite the right fit with my Nostalgia Audio Camelot. The cable comes with a lifetime transferable warranty, and will replace any connector free of labor charge, so even if one end of the cable is not your preferred termination, you can have that changed for far less than the cost of buying the cable new. It comes with the case and warranty card. Shipping and handling and PP fees are included. Any questions? Feel free to ask! Parden my feet in the first picture.
