​It looks great that the cable is thick and the two usb connector are in metal shell.
The Audio connector is well soldered and the spring will surely make it stay longer without dammage.
However the cable is great to use with a beyboard but it doesn't support fast chaging for a smartphone.

Because their internal wire diagram are different.
