My audeo pfe012 just broke down, so I'm looking to buy a new IEM for under $300. I've narrowed it down to shure se425, se315, and vsonic gr07, but open to more suggestions. I listen to just about everything, but mostly to Westlife, Eric Clapton, Taylor Swift, Avenged Sevenfold, and Birthday Massacre. My source will mostly be an ipod touch 3G. Which would you guys recommend? Thanks.
