First Impressions of the IE80/ Comparison to IE8
After plugging them in for the first time my thought was: “OMG, even more bass than on the IE8?!?”
In the end it´s hard to tell whether the sub bass quantity increased or sub bass just comes to life after the reduction of the mid bass hump.
Overall, the bass is really nice now, deep, full and most importantly, it doesn´t mess with the midrange anymore.
I would prefer a tad less bass on some tracks but they are the minority.
I guess the bass hump shifted way down to the lower frequencies as james444 already said.
What I love most is the clear separation between midrange and bass, one of the weak points of the IE8.
Midrange really shines now! The main reason is the reduction in mid bass, but there´s also a slight improvement on tracks without bass due to the change in presentation.
Mids are a bit less laid back, more upfront. The veil may not be gone completely but it was lifted a bit.
However, the soundstage got smaller in order to get this more intimate presentation, which is ok for me.
Treble didn´t change. This is a good thing, since the IE8´s treble was known for being smooth, non-fatiguing, with no sibilance at all.
The IE80 is just more fun to listen to than the IE8. The sound is warm, smooth, more detailed, doesn´t lack clarity and is even more involving because of the more intimate presentation and clearer midrange.
I´m very pleased overall
