Sorry to burst in, but they could well be fake - the Chinese replicas are spot on with packaging, etc. I have had my fingers burnt with eBay a few times with Monster goods, so I started Googling and found DHGate.com - the biggest supplier of Chinese fakes to western consumers who then resell on...

These look amazing, and they work with the full range of Monster gear! Universal Music UK have taken over European distribution on the web site, but they're only doing the headphones and earphones at the moment. :(
