This is appalling, but I'm aware it happens sometimes. I've
observed a similar thing with Chinese condenser microphones,
including some relatively expensive ones. Now I always check
polarity against a known good mic whenever I buy a new one.
Looks like I'll also have to start checking other gear.
Thanks for the warning.
