Listened these FH1s recently, and want to share my opinion of that model.
Fiio FH1s - neutral, but with a branded presentation.
Low frequencies.
Good, fast, not boomy.
Reverbs are nice and bold.
In general, the bass is like neutral headphones.
Middle.
Low-middles are slightly reduced to a pit.
The male vocals are not so expressive, the instruments are not corporeal, really like those of the “neutral” headphones.
The very middle is accented. Detailed, excellent separation of instruments and drive.
The high-middle frequencies are uplifted, the female vocals are very expressive and sound close, the metal can be a little harsh.
High frequencies.
Clean, detailed. The attacks are good and biting, fast, a little "ringing". On fast metal, “Architects - Doomsday” get a little messy due to the artificial "lengthening" of the far treble.
In “BFMV - Hand of blood”, only the not pronounced vocals are a little annoying, but all the instruments play perfectly, completely and flawlessly. During the solo part, the treble is also played out completely audibly and without distortion, even on a dark source.
The scene is noticeably more than average in width and slightly more than average in depth. Slight holographic effect like in Intime Kira.
Bottom line: great try Fiio. They sound similar to the largely improved TFZ King Exclusive, but with less bass, but generally better bass reverbs. Low-mids and High-mids are the same as TFZ King Exclusive, longer highs, the stage is slightly smaller than that of the King. Headphones can be founded
here.
Who doesn't like the Sino-Japanese feed (Similar to Intime Kira and, judging by the reviews, Intime Sora light) and needs Harman or Sony feed - pass by. I'm not so picky, the main thing for me is not to spoil my favorite music, or to make it even more interesting, bringing to the fore the details that were previously invisible. FH1s are just that.
