Ok, so how do I resolve a connection problem? I have other cables as well that have microphonics on just the Blackwood, no other headphones!
First of all, I'm guessing you are talking about mechanical noise and not microphonics.
Perhaps the full wood cups transmit the mechanical noise to a greater extent than your other headphones. If that's the case, that's just life. If the problem isn't present with a cable with proper dampening, then I see the problem as already having a solution.
We are talking about a custom tuned headphone. A cable should be nothing more than a transport. In this specific case there is no reason to use a cable that colors the sound when it can be obtained by asking for such a tuning.
I've built a lot of cables. Some are made for desktop use and others for portable use. I specifically try to make the portable use cables to dampen mechanical noise as long as it's possible with the desired style.
That said, this headphone is likely a desktop solution for the vast majority of users. That likely being the case, mechanical noise on any cable would be minimal.
I get the feeling you are trying to use a headphone and cable designed for desktop use as a portable solution. Something to consider.
Based on your responses and particular situation, I'd recommend using a cable that provides the level of dampening necessary to solve the problem. That is a much more realistic option than hoping for a complete structural rework of a headphone to comply with your particular situation.
Perhaps Zach will add additional mechanical dampening at the connectors entrance in a future iteration for people in your specific situation, but that is for him to decide.
