Back when I bought my first pair of balanced-armature IEMs, the UE TF10, I had this weird sense of superiority. Because everywhere online said BAs were the new tech, wiping the floor with dynamic drivers in every way — superior resolution, badass multi-driver setups, vocals so poisonous it hurt, etc., etc. Looking back now, BAs aren’t all that. Not that those strengths are bad, I’m just saying that when I listen to music with BAs, something always feels missing. Sure, the Focal (Phonak) female vocals were poisonous, sure the ER4P’s treble was transparent, sure the UE900 had strong instrumental expression — but it never quite had that flavor. A while back I was eating with a friend. The restaurant had a small stage, and a resident singer was up there performing “Love Like a Tide.” After that song, I think I understood what BAs lack. What’s missing is that sense of atmosphere, like sitting in a tiny bar and feeling the music reverberate through the space. BAs are too cold and clinical — that’s when the dynamic driver needs to step up. The Sennheiser IE 80 is probably a pretty good dynamic.
