Watch out!!! The fakes are about
Even though they have been around for more than 25years now the HD25 have, up until recently, they have not been faked. But while doing a search on alibaba the other day I spotted what looked like a replica pair so thought I would order them and see what turned up. On the site they were not advertised as sennheiser and had no logos but when the box arrived I realized these were relatively convincing fakes.
The box looked almost identical to the original, some parts were a bit glossier than they should be but all in all a good replica of the original box. The headphones inside, at first glance, look like the original as well with all the appropriate logos.
Here is a quick video guide to help tell the difference and spot a fake
