Anybody have experiences with iems? I can easily find good performing iems with balanced tonality that is highly resolving, but it's difficult for headphones. They come off more colored. Perhaps iems have less variables such as ear shape, and can be tuned much easier with balanced armateur drivers. I can easily find highly resolving and balanced tonality in TOTL iem space. But also, pricing for iems went up significantly, hence disinterest at this point.
Good iems have smooth and detailed treble. Headphones tend to either bright or dark, hard to find a middle point. There usually a peak somewhere, etc.. Also, you got to worry about dips in headphone response and all that. Full sized headphones still has ways to go. Headphones are pretty complex to tune well I think. First you have to have good drivers and then worry about sound effects from the housing, and then individual ear types(shapes, etc..), the pads, etc.. And all talk about DACs, Amps, uuhhgg.. iems are just simple.
