Of the options in this price range, my vote is for the 710 to match the OPs demands. Excellent for the money, especially for the $82 I paid at Beach Audio. I need to use the Comply to scale back the treble, but on balance, after 100+ hours of burn-in, the 710s are the best I have heard at this price range. I also really liked the PFEs, but to me, they are phones that need an amp to hit max potential. And I have owned many of the phones on that list above.
Oh, I have the S4s and find the treble to be harsh, even with burn-in. Not terrible, but just not right to my ears. Certainly, not as good as the 710s.
And I would not call the 710s FOTM, more a refinement of the 700/751 series, and a big step up.
