I recently bought a pair of Heir Audio 3.Ai. They are aesthetically beautiful, but the sound is just not doing it for me. For all the hype about the bass, I find it to be underrepresented relative to the treble. The highs have an ice-pick/piercing quality that is painful on ~60% of mixes. It especially comes through in intimate, close recording of female vocals — the "S" sounds on the voice or from hi-hat cymbals can be painful.
I do appreciate the clarity from these, but the treble is overdone. The V feels more like a slight bump to the bass coupled with an extreme treble peak.
So what IEMs should I replace them with? I'm OK with a "fun" signature and would prefer an exaggerated bass presence (should have at least as much as the 3.Ai). Treble and clarity is important but can't be overpowering.
Budget is ~350, so I'm looking at the Westone offerings at that price.
Edit: in hindsight I see a lot of these complaints I had were due to an improper seal. See last post.
