I think the title says it all. What are the best headphones, open or closed, that need no amping, modding, or burning-in to sound great? If I just want to plug something into my ipod and be on my merry way, what should I buy? Suffice to say, many will likely improve with amping, but let's avoid debating the use of amps here; the purpose of this is to recommend products to people who have no intention of buying an amp, cracking them open for modding, and don't have the patience to burn them in (or don't believe in such a thing for whatever reason). I'm hoping this will become a useful place for people who just want to buy a set of cans and be done with it, but don't know where to begin. This will likely be most useful to new head-fiers, so I'm hoping people will be helpful when questions are posted. (To be honest, I don't have a wide range of gear experience, so this will be informative to me, too.) Have at it!
