The cords of 1 meter stopped working either because the USB microphone connector is no longer made at all, whether on a Nexus2 a Nexus4, or to charge a battery Anker; or dysfunction so came the cable itself, which "broke" at the connections (see photos)
The cables of 1 meter was used in a car connected to a USB port of desktop, to an external battery (Anker) in a purse or in a (large) coat pocket.
Resolutely poor quality product should be avoided.
So I pulled over the cable end Anker, certainly more expensive, but much better.
And finally, no placebo effect, so that I doubted the posted reviews of the "debit" charge, it is reduced effect with these cables.
In short, I tested the cables 3 to fall back to those 3 to 22.
