You misunderstood I was referring to the overall sennheiser signature which is true for both ie800 and 660s and agrees with mojo, you know you are listening to a sennheiser product with both.As far as everything else i agree,the ie800 has noticeably more treble extension,air,better bass quality as well as clarity,but it is not a bright iem,slightly on the warm side it is just that Hd660S are noticeably warm.HD660S has the thicker mids though.
Yup, you are right.
But to be IE800 still on the bright side but not overly bright.
