Yeah, what is it with those idiotic "Beats by Dr Dre" headphones? The other day I noticed a range of "Bob Marley" headphones in the airport, which I'm even more perplexed by. I have a pair of AKG noise canelling headphones (K480?) which look almost identical to the K451 you mention. They sound OK-ish, but the noise cancelling is pretty pathetic, and you seem to pay a lot extra for that feature... I'd save ?70 and buy the cheaper ones.
