  1. Hello Kim,

    We have 2 cable options for the HD650 headphones

    What to expect from our E-Series and Endorphin (100% of the improvements below results will depend on how well your system is setup) :

    The ESeries will offer the biggest step-up from the stock cable (and any other aftermarket headphone cable available) as it will considerably improve the performance of a headphone/IEM offering great balance with full rich sonics, deeper in site into the music along with a very noticeable increased clarity of bass, mids and high frequencies. The sound-stage will also noticeable improve both in width and depth. The E-Series is also very soft and flexible using our proprietary ultra-pure copper conductors inside a proprietary soft sheathing and incorporating extensively treated custom connectors.

    In comparison the Endorphin design has 95% of the dielectric the E-Series uses removed so it utilizes the least amount of dielectric and non-conductive material of any headphone cable cable available – the surrounding proprietary outer sheathing “semi-floats” over the inner conductors which do not use a dielectric which eliminates the harmful effects of the dielectric material. So the Endorphin design will do all of what the E-Series offers and in addition introduce a pure, rich musicality that can best be described as if the equipment generating the music has been completely removed from the process of generating the music and you are left with what is very close to pure, live sound.

    The FS-Integrated Flex Splitter is where the headphone cable splits and we cover it with a white label with our logo on it.

    The WS-Cocobolo and WS-Ebony Wood Splitters are made of these woods and are used as splitters where the headphone cable splits.

    See the following pictures on the link below which shows the Actual color of the Ebony and Cocobolo wood Below that is a photo of an ebony wood splitter ( covered in a plastic wrap ) and Ebony XLR wood shell connectors on the headphone cable:


    Thank you and please let me know if you have any other questions.
