Not sure what the big deal is here with this headphone cable.
For JOAL, as we stressed in the video, in order to keep costs low we didn't have the wire itself made for us. We rocked through dozens of different wires from various Asian wire manufacturers (different colors and dielectrics, different conductor counts, different conductor materials) and ultimately found one that [almost] perfectly fit our criteria, then contracted out the assembly using our custom 'D' shaped 2.5 mm mono connectors that fit into the D shaped opening on JOAL (and Diana). The cable assembly is made to our spec. As it sits JOAL's stock cable is not sold anywhere else as no one but us has our 2.5 mm plugs.
With Diana headphone cables we injection mold the 2.5 mm connectors to the cable. For JOAL we created a solderable 2.5 mm plug shaped to perfectly fit inside JOAL's frame that can be terminated by anyone skilled in the art (without the need for an injection molding machine). We also make available for purchase these D shaped 2.5 mm mono connectors to other cable makers, some whom Diana customers requested to terminate their aftermarket cables with.
Side notes... All the aftermarket 8/16/xx multicore woven headphone wires you see out there are sourced from Asia (mainly China). US and European wire manufacturers don't make this stuff, not competitive.
And as far as audio connectors go, since we've been making cables for over 30 years we have a sh'tload of connectors in-house. Many we designed for our various cable lines, and many more made by others such as WBT, Wattgate, Furutech, etc. If someone want's a cable made with a particular connector, just ask. Otherwise trust in us to choose the right connector for the job.
Thanks guys!
