I don't think either of the two is bad (at the moment). I bought these adapters to connect headphones. Today, on the 20th, one of the two adapters fell apart. I received them on the 18th. I blamed the headphones for the squeaky scratchy sound and when I unplugged the adapter to try a different amp it fell apart into 3 small pieces. It looks like the press fit wasn't pressed in. I think QC should do a better job. The other adapter seems to work fine (although I'm a bit irritated myself), but I'm concerned and looking for backups. They were cheap and I think (in this case at least) I got what I paid for.
