It turns out that actually the self solve webpage can't find ANY Beats serial numbers. Bought from eBay brand new, £80, considerably cheaper the retail price of £169. So yes, both of these might indicate they were fake but the seller provided me the receipt that showed they got it on the offer free with a MacBook, and assured me they were real. In the end I believed they were real, but I decided to sell them on for £100 as they seemed quite poorly reviewed.
