FiiO FH7S Review

Build and Fit

The FH7S feels very nice in hand, and I think it should be a reliable item for extensive usage. Everything is beautiful and complete, and the shells are simply fantastic.

FH7S comes with a high-purity silver cable with 8 strands, for a total of 152 wires. Each wire is individually isolated. They are braided together in a Litz pattern. The cable feels very high quality with good flexibility and tensile strength.

The FiiO FH7S has an ergonomic shape for most ears out there. It’s quite round, like the previous models, but the difference is that this design provides a fuller fit. The fit is more complete and ergonomic for a Universal IEM.

The supplied tips work very well. I chose the silicone ones, despite me usually liking the foam tips more. That’s because the IEM fits very well and I don’t have to use the foam tips to get a flush & secure fit. The silicone tips do the trick and they’re enough to give you nice isolation. You can opt for foams to get more isolation though.

The IEM also feels quite comfortable and I did not feel any pressure. The isolation is not the best of course, given the semi-open design, but it’s still good. Overall an excellent and very comfortable fit experience.

Sound Quality

The FH7S is a very smooth-sounding IEM with good naturality, balance and space. It has good resolution, transparency and separation. It’s mostly a balanced IEM with a slight bass warmth and punch. It packs good clarity and spaciousness, with a good sense of realism and nice tonality.

The presentation is close to neutral with no additional lift in the spectrum. Unless you utilize the other nozzle filters. The FH7S, while being well-balanced, also carries a dynamic approach with a quick nature. The good thing about the FH7S is that the presentation always feels natural and flowing, with good smoothness and timbre.


The FH7S’ bass is impactful, strong and deep. However, it stays under control with good decay and texture. The kick is satisfying to hear, and it would be great, especially for bass lovers out there. The texture of the bass is the most impressive part of the FH7S. The quickness is right there despite the impactful and somewhat heavy-hitting nature of the bass.

So overall the bass response is pretty much similar to the FH9. It’s not a reference-like response, since it doesn’t have that certain flat and super quick character, but it’s fun with its impact and texture. It provides musical enjoyment in this particular era.

I like the “balanced” tips best and they extract the most realistic bass presentation from the IEM in my opinion. Bass filters add more weight and lift to the sub-bass region particularly, making the bass meatier and more impactful. It’s not a drastic difference but think of it as an EQ. You have more kick and rumble. I would go with the balanced filters myself since I think the bass filters take away the balance and realism of the IEM.


The FH7S gives very clean mids with good enough transparency and resolution. The mids sound coherent and it also has good body and note thickness. Timbre-wise this is quite accurate and realistic, and there’s good warmth in here. However, the resolution is not quite the same as the FH9, and it’s not as transparent. Still, it has good clarity for the price level.

I think the FH7S has a very good mid-range with very nice transparency, mid-bass balance, tonality and dynamism. There’s great smoothness and easiness in the mids with good air and separation. From a technical standpoint, the transparency, air, separation and resolution in the mids could’ve been better, but for that, you need to look at the FH9. In terms of naturalness and timbre, the FH7S has good musicality. The IEM has a very nice tonal accuracy, especially for instruments.

A keen audiophile and hobby photographer, Berkhan is after absolute perfection. Whether it is a full-frame camera or a custom in-ear, his standpoint persists. He tries to keep his photography enthusiasm at the same level as audio. Sometimes photography wins, sometimes his love for music takes over and he puts that camera aside. Simplistic expressions of sound in his reviews are the way to go for him. He enjoys a fine single malt along with his favourite Jazz recordings.
