HifiHear F30: Underrated Contender

Hello everyone,
in this review i’m gonna take a quick look on the HifiHear F30, a new product from this new-sounding brand that was sent me free of charge by Sunny from Better Audio Amazon Store.
I’m leaving the link where you can buy these IEMs:

Even if this was provided as a free test sample, my opinion is based on my experience with the product and it’s not influenced by the fact i got these for free.

The IEMs has been tested with:
– S7 Edge with Neutron Player and Neutralizer
– Benjie S5 (AGPTEK m20)
– Presonus AudioBox iONE
Tracks were for the most part 320Kbps mp3 and WAV, and a few of them were FLAC ones.


The package is the one in the photo. What’s inside?
– 2 packets of tips: S,M,L sizes. Wide bore tips in one packet, spinfit clones in the other one
– 1.2m lenght MMCX cable
– zipped case (maybe a bit tiny for these IEMs) without any logo printed on
– IEMs

Sincerely, i wasn’t expecting so much quality speaking about the cable, considering that the majority of brands just put bad sticky cables with the IEMs.
The cable is a twisted silver plated cable, with a rubber layer. Touching it is a pleasure, it is lightweight and it is really hard to tangle the cable.
The upper part of the cable has a pre-made hook that is way better than the memory foam hook provided with the classic cheap sticky cables in my opinion.
On the other side of the cable we have a gold plated 90° angled gold plated 3.5mm connector: again, imho, a better choice instead a straight one.

The shell is transparent with colored faceplate (Blue, Red, Black, you can choose while buying) that has the HifiHear logo printed on.
Everything seems ok and doesn’t feel cheap in the hand as this is very well built as a plastic shell.
We find L and R indications on the shell and the MMCX connectors are gold plated: the cable has to be connected like this –> after the cable splits you have two cables, one for the left and one for the right. The one with the blue stripe goes in the left IEM while the one with the red stripe has to be put into the right IEM.
There are 1 DD and 2 Bellsing BA (can be seen through the shell that they have the classic “b” painted on). As they are not in the nozzle and that the shell is not metallic, i expected less brilliance than IEMs like the ZS6, but we’re gonna speak about it in a few words.
There’s the usual grill at the top of the nozzle, and even a nozzle lip in order to secure the tips.

IEMs shape is the one of the BGVP DS1 (which i don’t own but i’m really curious to hear as the driver configuration is the same), similar to the KZ ZST one.
The IEMs are not huge but not for who has very small ears, but that’s just my opinion as this is a very personal thing: every ear is different!
Anyway i find them comfortable and lightweight and they stay in my ear pretty well.
Isolation by external noises without music playing is ok, not excellent but not bad.
People around you won’t notice a lot about what you’re listening as isolation In–>Out is good.

Now the critical factor that decides if something has to be tried or not: how do they sound?
I listen mainly EDM subgenres, Dupstep, Future Bass, Euphoric Hardstyle, Bass House, Midtempo and downtempo, darkwave, drum’n bass, but i even listen to many vocal tracks, moreover female ones.
I always search for IEMs that have a little bit of emphasis in the lower region, and can sacrifice mids with some recession if they still sound clear and natural. I love vivid and sparkling highs if they’re not at a headache level. Soundstage has to be at least average with a bit of air. V-shape signature is my favorite.

STOCK STATUS –> plug’n play
Lows: sub-bass is there, the extension is not amazing but precise, i usually prefer a more emphasized sub-bass.
In some tracks i miss some body, moreover when some 30hz-40hz 808 comes on the way and the mid-bass is forward leaving the sub-bass “body” back.
We have a little lift in the mid-bass, at first listen i felt everything was congested. Kickdrums play well and controlled, with fast and well managed transients. This kind of lift adds warmth to the sound.
Mids: recessed but i expected way more recession. The lift in the mid-bass puts male voices in the front leaving some synths in the back and making female voices a bit veiled by a strange warm feeling that i usually don’t like so much.
Highs: enough airy but not enough vivid. Upper treble is not well extended in my opinion, but everything sounds natural and precise keeping a good level of detail (not great anyway, i would have preferred more brilliance here). Probably a metal shell could improve this.
Soundstage: the lift on the mid-bass and the “early” roll-off in the upper region makes me feel a little reduction in the soundstage. Sound is a bit more intimate and positioning is not well presented around, i would say many instruments sound like if they’re near the ears. Height and width are on par with some competitors, i would say average. Depth is a bit disappointing, maybe a bit below average.

I wasn’t blown away by my first listening session so i decided playing with the EQ could have been a good idea.
I got another surprise: the drivers react very well when equalizing. I wanted a more fun experience while my friend said he was ok with them as he listens Imagine Dragons and Maroon 5 mainly.
After some EQ:
Sub-bass gained more presence, coming out in a strong way that puts me in the rumble when needed. The lift in the mid-bass gets less noticeable, making the sound less warm and a bit more brilliant and airy.
Soundstage gained some space making the separation a bit more defined.

I have to say i was surprised by this, i even find a good preset on the DAP which is the Dynamic Bass Boost when i want some energy on the lower region (this anyway increases warmth but sometimes is ok).

If we try to change the output, the IEMs play in a different way: for example they sounded congested when plugged in the smartphone while they sounded vivid and refined when connected to my Presonus AudioBox iONE.


Even with many strong competitors in the same price bracket, HifiHear distinguished his F30 with a good package overall: a good cable, two sets of tips, a coherent and linear sounding IEM that i personally recommend moreover to people who like to play with the EQ.
It’s lightweight, comfortable, sounds good with some tip rolling and can be great applying an EQ (they’re very capable just like many people say about the ZS10 that i still haven’t tried enough).
What can i say is that it is really hard to push this product against the competitors when they have many awesome reviews (es. BQEYZ, KZ flagships at this price tag) and hype around.
Price/quality ratio is not outstanding if we speak about the IEMs themselves, as there are many technically superior IEMs at a lower price, but this is ok as HifiHear provides a good package with a good cable that is really hard to find in this category.
Overall, a good start for this brand that seems enough prepared to compete with bigger brands.
Can’t wait to listen to their next products, waiting something that can replace my obsession with my beloved ZS6, which were returned to amazon but still my favourite IEM.

  • Mid-bass lift is a bit too much in many cases
  • Treble extension is a bit disappointing
  • Much competition at this price, there are better products in the same price range even if not with the same package
