What should I purchase?

[Gaahl]

Leave the Beats alone and buy yourself a pair of Shure, Bose (yeah don't hate, Bose are awesome) or Sennheiser. I wouldn't spend my money on a new iPod since iPods are durable and incredibly well made, and there's absolutely no need to change it unless it's broken. I had a 6 years old 2nd gen iPod nano and I just changed it to buy a bigger one even though I wouldn't have changed it if it wasn't really necessary as it still works as a charm.
