I agree with compare F3 and F2. And I agree with the 8.2 is different from to F3. FIBAE3 isn't baby Harmony 8.2, because bass, mids, and treble are very different than bass, mids and treble on H8.2. But with Cayin N5 II on cable FAW Claire Hybrid balanced F3 sound similar to flagship CIEM, because Cayin N5 II is very warmth, he have peak on higher bass and lower mids, attack and decay is very slow, treble not crispy, not clarity. Cable FAW Claire Hybrid have warm tone and slow attack and decay.
