FiiO L3 Line Out Dock (LOD) Cable For iPod and iPhone
I just got this in the mail and immediately I went to go test it with my FiiO E7 and Grado SR80is. To my disappointment, the left channel simply refused to work unless the cable was held at a very specific angle. I'm hoping this is just the one I got. I've heard many good things about FiiO products and I love the E7. I'll be ordering another and updating this review once I get it.
