Configuration: One 13.6mm DD plays mids and lows + 2*60235 dual BAs play mids and highs + one 31736 dual BAs play highs. The silver cable is really thick(the cable got 224 wires!).
Design: The designer may have designed the FH9 after being drunk - its design is so bold!
So FiiO provides two color schemes for the FH9: All Titanium and Black+Gold.
Unlike the titanium version, which has a subtle frosted feel, the black version has a smooth glossy shell, and its black x gold color scheme has a feeling of luxury.
You can also see its semi-open design from its panel, which is its most special design. Some people may be curious about the sound leaks of the FH9, but for real, you got no needs to worry about that.
The semi-open design of the FH9 greatly improves the soundstage and increases wearing comfort.
(The above picture is the measurement of Crinacle.)
Sound: The FH9 got a neutral to warm sound. I will use the M11PlusESS with plenty of power and the Sony ZX505 with average power for testing, just to simulate two situations. But all the tests are under 4.4mm balanced output.
Bass: The bass of the FH9 will not be like closed-back headphones, which will make you feel like your brain is shaking when listening to electro and heavy-bass songs. On the contrary, it will release the excess bass, so that you can get more comfortable bass and bigger soundstage. You might worry about its bass extension or subbass, but they are just good to me. But please note that the FH9 will show stronger dynamics under sufficient power.
Midrange: The midrange is still FiiO-ish. It maintains a decent thickness while still having the proper resolution. It is worthy of praise that the connection between the dynamic driver and the balanced armatures is smooth and flawless, I will say there are no gaps between them. Its midbass doesn't quite stick to the Harman target curve, as the latter got a pit at 250hz. That midbass will make the FH9 sound fuller and richer, But for users who prefer Moondrop's tuning, the mid-bass may be too much for them.
Treble: I like its treble! The treble of the FH9 is smooth and accurate, especially in the treble falling part, It falls off slowly rather than abruptly, so the treble retains plenty of details without being harsh. The treble part is played by the BAs, and the dual BAs in the nozzle playing the treble part above 7khz, are located closest to the ear canal, which can reduce the attenuation of the extremely high frequency, maintain high resolution, and restore the original sound.
The FH9 also comes with replaceable filters so you can use them to adjust the amount of treble. But the fly in the ointment is that when the FH9 performs some tenors, the restoration is not that strong.
Summary: The FH9 got a neutral and warm sound and its soundstage is amazing.
If you have the budget and want iems with a warm sound, then the FH9 is eligible to be on your shortlist.
