U6t

Vocal-forward and emotionally engaging… the IEM that comes to mind is the U6T from 64Audio.

Get a used U6T for $600 👍

you mention 2.8K max yet mention devices that are inexpensive, so I assume your currency isn't USD. Moondrop Chu 2? but if you are talking USD, campfire audio Clara/Andromeda 10, 64 audio Volur are bassy, campfire Astrolith is snappy/punchy in its attack, 64 audio u6t is very utilitarian(all genre)

U6T is great, as long as the OP can buy it. (Being its a kilobuck set) Though a much cheaper set maybe, we don't know the price limit.

Demoed 64audio duo during the Hifi show. It’s like letshuoer s12 but perfect. They have the full-bodied vocals that I am always looking for. So I jumped into the 64audio train and talked to their staff what I am looking for in an IEM. I end up with U6T and it’s perfect — the full-bodied lush vocals inside my head that it feels like the artist is whispering to me, makes every track emotional. My daily driver before this was TFZ No. 3 so imagine the jump. I would say totally life-changing. During a trip to SG, I visited The Hangout by Crinacle and Zeppelin. Got to try lots of TOTL IEM. That experience reaffirms that 64audio is my best choice for vocals. My star IEM on that trip was the Monarch MKII because it has the widest soundstage out of all the IEMs I have tried, couple with the thumping bass — feels like I’m in a concert. Also tried the Annihilator. I was not impressed at first, not until I got home and listened to some music I used with the Annihilator. It was like a night and day difference when it comes to the highs that I could not hear the sparkle I heard from the Annihilator. (Tho I still don’t like how the vocals sounded in them — they sounded thin but maybe because of the airiness.) My next goal is to find a moderately-priced IEM with EST driver that gives the same sparkle to the highs.

Unfortunately in my situation, I need to be able to hear everyone in the band plus backing tracks as I monitor everything while performing. Ideally I’d do the U6T custom molded but might have to go this route for now.

I have some kilobucks iems coming from sub 500 stuff. The thing is while sub 500 stuff sounds good, or great value they usually just tuning good, but lack some technical performance and soundstage. At least thats how i felt. Kilobuck stuff tends to give you extra 10-20% of that like Monarch mk2 (superb vocals with superb resolution) 64 audio u4s/u6t (better instruments separation and soundstage) Westone mach 80 ( best detail retrieval and resolution under 2k usd) Etc etc.. This is just an example of course theres many other kilobucks that are good too but for me 1000-1500 is where the diminishing return start to kicks in

we've made a semi-open back IEM called Duo, but it has since been discontinued. A very warm tone, with a fairly laid back pinna gain. Something that may interest you is our IEMs that are built with the interchangeable apex modules. You can go from the m20 modules which is almost fully occluded to something like our mX modules which really feels and sounds like an open back when you're wearing and listening to them.
