So thanks to
@NickMit for pointing it out, and
@Scorpio1957 for explaining where exactly it is. I manged to audition Odin and Hero in Harrods.
The fellow in listening lounge actually let me use my own cable, tips and dap! It was very easy to compare to my LX with my own music i know well.
I was just blown away by Odins technicalities. That soundstage is just amazing. I used it on my moded dx228 on high gain and was surprised that it did not have any background noise.
The treble and upper midrange was just so spot on for me, i actually thought it will require warmer dap but no, its all perfect no harshness, no sibilance.
Bass, while its nowhere near LX, it actually is not at all bass light. And even being basshead-ish i could live with it, no problem.
Also what i noticed, at least bass did not respond much to EQ. But then i was never a fan of EQing bass.
Hero? When i first saw FR graph i thought. Nah, not for me. But actually it was quite enjoyable. Its not Odin or LX in technicalities, but not far and still impressive. For a price they are amazing. Id take it over something like CA Atlas any day.
Bass is slight more prominent than Odin. But less than LX and with a bit more mid bass focus than the other two.
I was expecting it to have thicker midrange and while warmer sound than Oding it was actually just where i wanted it to be with the rest of signature. Maybe because treble is slightly more forward.
On hero i could clearly feel the difference between estat trable and LX BA treble.
(Odin did not have that much obvious estat smoothness. It was actually quite sparkly) im quite treble sensitive and yet i did not find that forward Hero treble fatiguing at all.
After today i think i know how i would like my perfect iem to sound. It would be Odins grand soundstage upper mids and that fantastic treble combined with LX bass with maybe a touch less midbass. (Or in other words Odin bass FR curve with few dbs more in quantity.)
Really happy to have that oportunity to listen to EE new babies. I can now officially declare myself EE fanboy as i love all 3 of their iems.
I only had a listen of each for 20-30 mins and i mainly listen to electronic music. So take my impressions with a pinch of salt. There are plenty owners who can give better impression than me.
All in all it was a fantastic experience.
