I see.. that's too bad. I'm pretty happy with the Oyaide right now so if I do order this it would just be out of curiosity. I'm more interested in their other cable because I think it might fit my Spirit Pro.
Hello Sig Pro brothers
We may have another option now...
FiiO RC-HD1 Replacement Cable for Sennheiser HD598 Headphones
They might be just the thing for people who wanted a more flexible cable. Not sure if they can deliver the same improvements of the Oyaide.
