In 2004 the Gibson company bough the audio divisions of Dutch company Philips and Japanese company Onkyo. So Gibson would be manufacturing the products (e.g. headphones), but selling them under the original names. They spent a lot of money on it, and that's the reason that the Gibson company is now bankrupt. They also bought other brands like Tascam and Teac.
In my hometown there were still working like 60 people for the former Philips audio division that was bought by Gibson. Today is in the newspapers that that division will be closed.
