I don't really feel this is the case. I think the HFI-580's do in fact offer a better sound, while still being in the same sound signature. Both have somewhat heavy-handed bass and treble, but the difference is that the HFI-580's have less recessed mids. (Actually, the mids aren't just "less recessed", but are quite nice.)
And while the HFI-580's have more bass with bass heavy music, I also feel they are less bassy with music that isn't bass heavy. The M50's, to my ears, added bass that wasn't there, not the case with the HFI-580's.
Yep, agree. And 580 has better soundstage as well.































Well folks, you've heard it here. They rule. Like O'Doyle. Also, gotta love our kinship system and it's ability to conflate those kinds of relationships.
