Sorry, some answers made me mislead about this, and I don't own Odin so I have to change mine :
The two are still the same
1. Sony IER-Z1R
2. Unique Melody Mest OG/Mk I
But the current fave I got recently :
3. KZ PR3 (Modded)
2024 : Year of Intestines
Keep them coming!
From my limited experience journey, of any price, I think the sweet spot of best of the best sounding x value are sit somewhere around $1,000 - $1,500.
I'd like to have as value as possible IEMs that can satisfy me without lot of nitpickings and have real TOTL sounding, but IEMs below $ 1,000 still can't representing TOTL soundings, the great tuning and great technicalities, without real caveats. It is really worth to save and spend for one someday if you never try them. I know a kilobucks set is expensive but they offered nice sounding in 1 package with good quality driver, good tuning and great technicalities.
Something like Sony IER-M9, 64audio U4S, UM Mest, Thieaudio Monarch MkIII, etc are the gatekeepers, you just have to pick wisely.
On other side, multikilobucks above $2,000 aren't justified enough for me, with very big diminishing returns, like slight refinement from those $1,000-1,500 sets but with double or triple the price.
There was polling about best of the best IEMs of any price on watercooler's thread on 2023, the Fir Audio Radon Rn6 ($3,200) was approved as the no 1 and Sony IER-Z1R ($1,700) on 2nd place. I forgot the 3rd place, maybe Annihilator ($3,000) CMIIW. To be honest I was quite surprised with the result, with those 3 beating lot of great contenders with multikilobucks tag IEMs. They are all great IEMs with only slight differences and more personal bias and preferences but with diminishing return is really steep here.
That is convincing me 1 more time that the sweet spot between value and performance soundwise are sit on $1,000 - $1,500.
Of course if money isn't an objection, you are free to grab the best sounding IEMs to your ear even with hefty price tag.
Just sharing my 2 cents here.
