thanks, i guess i should clarify on the sound, i'm looking for more and more neutral as time goes on (other iems i've enjoyed are SSR/SSP for example), i mainly want to hear what was recorded rather than whatever coloration is provided by iems tuned in specific ways. how much of a difference would JH be from say the "IEF Neutral" (instead of harman)? i guess my main goal is to just get pure original sound with as much detail/imaging as i can if that makes sense.. something like the z1r i found actually offensive
You mean the IEF Neutral curve on @crinacle's site? Harman curve is basically IEF curve with extra subbass. The most famous IEM tuned to the IEF Neutral curve is the Etymotic ER4, and trust me you won't like. The most famous IEM tuned to the Harman curve is the N5005, which is very similar to Blessing dusk, hence the recommendation.
There isn't a neutral standard in the IEM world. It is still an ongoing debate on what does it mean for an IEM to be neutral. If you ask me, IEF curve is way too bright, and Harman curve sacrifices too much lower mids. JH and the stage monitor type of sound is much darker and the mid/lower mid is much more forward.
