The whole concept of the Dual-Tone cable is to provide a high quality cable that covers the needs of those that prefer the 2 more common cable materials. The ideal situation is that the user will be satisfied with the sound as well as the comfort of the cable (we spent a lot of time making a cable with almost zero memory and is comfortable). Of course, that's the ideal situation and we recognize that there will be those out there that prefer a different material or maker of choice. Hopefully, there will be cable makers that will be able to provide cabling services for our connector and pin configuration in the future. We were also given a few suggestions that we're still looking at the possibility of exploring - nothing's set in stone at this time though. There have been suggestions of perhaps creating an adaptor, or to further develop our idea of the Dual-Tone cable and create cables with more materials in mind. For the adaptor, the question of bulk and comfort would be a big issue to overcome. Both ideas, especially the latter, would also take a good bit of investment and time to accomplish.
