Mine have arrived and sound is very promising (dub reggae, oh yeah!). But there's the same issue with the stock cable mentioned by others here. Screwed in all the way, only one channel and pulled out a bit, the other channel. My V-moda audio cable seems a solid connection (I think), although I haven't tried to wiggle it.
Is it an issue with the stock cable or the input itself?
EDIT. Arhh, I wasn't screwing the stock cable in enough. All's good now!
