Separate names with a comma.
The implementation of the bass emphasis looks very tasty.
Its definitely a unique presentation, but one you can get used to quickly :)
Nice review. even though I don't agree with some points (I don't think it sounds cool).
Was that a typo : "...The ES3 is a great triple hybrid..." It's all BA, is it not?
Yep typo - thanks. Fixed. I definitely wouldn't call it a warm earphone. The coolness comes from the upper mid-range and lower treble emphasis in combination with the very linear mid-bass. The result (when compared to many other earphones I own or have experience with) is a somewhat clean, lean and cool sound.
It's not warm but neutral with a musical sound signature, I'd say it's very slightly on the warm side due to sub-bass boost. But yes, it's not warm in the sense that it doesn't have boosted mid-bass and lower treble.
I guess we'll have to differ in the way we hear them. And to me - while they may have boosted sub-bass - they are not even close to warm. At least not compared to the [b]many[/b] earphones I have experience with. And whilst I agree with the comment that they are relatively neutral (as in flat) - most earphones I would describe as "musical" also exhibit a natural tonality (ie a slight mid-bass hump). To me the ES2 is the far more natural sounding and musical IEM of the two.
I guess I'll look forward to your review and your own take on them. My observations are definitely backed up by the measured frequency response.
