I heard this in another sub, that only tuning matters for IEMs but I’m not seeing it.
Aside from tuning what parts are giving advantages? The housing, the drivers, the materials used?
Example, the truthear nova ($150) is tuned nearly the same as the moondrop variations ($520). Does that mean they would have the same sound quality?
Hope this was understandable :)
If not, feel free to ask for clarifications!
