Andromeda is pretty much better in every way except maybe some midrange detail (SR is really boosted in this region) and isolation/fit/comfort.
I own(ed) both and interesting the Andromeda was sold because of comfort/seal issues. The Andromeda has an amazing soundstage and probably among the best treble extension I’ve ever heard though (check my post in Rank IEMs you’ve heard). If you want a cheaper Andromeda, the Comets are not a bad alternative. Inferior in every way but keeps the tonality of it.
If the comfort works out, I'm still gonna stick with the inferior IEM though because what does it matter if your ear is hurting every time
I'm very curious about the neutral part though. Everyone describes these as dead neutral so for the price, I wanted one in my collection before finding a neutral CIEM perhaps to replace my Andromeda. Who knows maybe I'll dig the Etys enough to make them my daily driver and call it a day.
