This cable is a little thinand flimsy but it controls volume perfectly.

I replaced it with a cheap "aux" cable, but that did not allow me to adjust the volume without digging the mp3 player out of a pocket, which is a hassle while skiing.

My only issue with it is the cable is kind of flimsy.

so I really can't call the cable gauge a fault or "defect"

but it works as it should.
