did the smart thing by doing the former, Radiopaq is carelessly banking on the latter to still go over well. Rather than producing a set of earbuds with customizable acoustics to fit whatever genre you find yourself into, Radiopaq's custom tuned earphones take that personalization away from the end-user. Oh sure, you could plop down for four different sets to handle your classical, jazz, pop and rock records, but that would easily go down as one of the most absurd decisions you've ever made. The company proclaims that each set actually can be used to enjoy other genres, noting that each pair is simply optimized for one specific style. Each package will go for £59 ($86), so make sure you choose carefully -- does your allegiance lie with The Cranberries or Taylor Swift?
