Yes, very different! 7Hz = instruments blend into each other more Fiio FH7 = more separation between instruments Initially, I liked Fiio FH7 more. But then -- on certain songs, there is too much separation... the melody deconstructs too much. Also: Fiio FH7 are brighter. For 2h+ listening...

Hi -- Timeless 7Hz and Fiio FH7 are the two IEMs I have gone through so far. Still looking for my "endgame" pair... Nice to meet everyone here!
