My first audiophile earbuds
Pros: - Authoritative, open and engaging presentation
- Big, punchy bass
- Warm, smooth, musical
Cons: - Treble can get drowned out in busy tracks
- Vocals can be too intense at times
This is my first review on Head-Fi. I don't have a lot of experience, but I'm a guy who loves to try different audio gear. I mainly own open back headphones and IEMs, so the FF3 was my first audiophile flathead earbud. I'll give you my honest, short opinion of these earbuds. I'll only talk about the sound, and I'm using the donut foams because I believe they provide the best balance.

It's been nine months with the FF3, and they are incredible. I didn't know that earbuds could have bass this good; bass quantity is not at the level of IEMs, but more than enough for me, and the quality is very nice, deep and punchy. I don't miss the extra bass of my IEMs when I listen to the FF3. The overall sound is warm, smooth and very musical. The best part about the FF3 is the presentation; it's authoritative, open and mesmerizing, almost like an open back headphone. I have some minor complaints: the treble can be lacking in busy tracks, and at times the vocals can be too much, and the detail is just ok. But overall the FF3 is amazing, so I can overlook details and just enjoy the music.

A noticeable improvement on my favorite bud (the EB2s) with REAL BASS.
Pros: -Build quality is superb
-Actual sub bass presence for an earbud - nuts.
-Textured, layered detail with nice depth
-Very present mids
-clear, clean treble
-swappable 4.4 and 3.5 cable ends
-gorgeous looks
-The cable is lovely (seems like the "Stiffness" has been fixed, mine was super relaxed right out of the box) and while fixed, I love the thin, delicate but sturdy stems that it allows them to have. i
-Lots of foams and silicone covers
-A sense of "bigness" to large, orchestral pieces
-Doesn't drown in complicated music
-No appreciable bass bleed at all
-The little pelikan case is LOVELY
-Plays very nice with tubes
-Manageable to drive with normal sources like phone/dongle
-Can be looped over the ear for better security
-Overall extremely musical, energetic, "fun" centric vibe
-Price to performance and build quality is excellent.
Cons: -The swappable ends require an annoying amount of force to pull out, and the registration mark to put in the new one is a little hard to see.
-The bass or balanced foams are mandatory - treble gets real piercing real fast in brass band music with no foams, the crisp, and the silicones. And it's gotta be bad for me to mention - I am a big treble fan.
-Fit isn't the best I've tried in earbuds. Not unacceptable by any means, but doesn't quite fit as well as EB2S or the standard MX500 shell in my ears. Nowhere near a dealbreaker though.
-I'd prefer better baggies for holding the various foams. The one-time use design is kind of obnoxious.
My favorite go-to for earbuds has been for quite some time the NiceHCK EB2s. They're clean, neutral, balanced, cheap, and the build quality is beyond outstanding. I was curious about these as everyone mentions they have real bass - something I tend to appreciate a bit more. And I'll be damned, there's actual sub bass. Not a ton, but for an earbud, it's amazing.

And in every other way, they're just a straight step up from the EB2s. I was hoping that, since they're 4x as expensive, but apart from lacking a microphone (which I do miss, I liked having the mic on my EB2s, so they're staying in my backpack as well) they're noticeably better in every way. I still rate the EB2s as a perfect bud for $18, but when an upgraded is wanted, these are definitely worth it.

The bass can actually keep up with bassier tracks, but it also works with the huge soundstage of earbuds to create a sense of hugeness to bands.

Imaging is great, in rock, you can hear that each drum in the drummer's kit is very slightly differently places. Bass texture is clean and doesn't bleed into the mids either, which are very well presented, with a slightly warmer presence. Treble is also superb - provided you're using the balanced or bass foams. With the "clarity" foams and silicones, stuff with high strings and horns (too many zoos in particular) gets VERY obnoxious - kind of what they are going for, but I love my treble and in some songs, those covers are too much for even me, and I adore grado sparkle. The bass and balanced foams REALLY temper that down to just right. Overall, I think I prefer the bass foams most. I do notice a bit more subbass rumble without much loss in detail. They're great foams, too. I threw them on my EB2s and noticed an improvement in them too.

Overall, A+ out of me. I haven't heard anything better in earbuds, and I really like earbuds. I've heard that the FF5 is less bassy, with more detail and space, and they're more "different things" than competitors, so they'll be on my radar.

I know earbuds are more particular about whether or not they "fit" than IEM's, but the light, spacious, airy fit that doesn't fatigue your ear canals after hours of use is something definitely worth considering as a supplement to some good IEM's.

They remind me a lot of a MUCH more grownup/premium version of the Koss KPH40i. Same level of ethereal comfort (with yaxxi pads) with nice, impactful bass, very persent mids, and smooth, crisp treble.

I also think maybe fiio fixed the "stiff" cable. Mine was supple and relaxed out of the box.

If you don't know about earbuds, get the standard VE monks for $5 and if they fit you/fit your vibe, if you can afford the $88 (on aliexpress) or $100 (on amazon) these are a very premium option. If you can't swing the $100, the $18 NiceHCK EB2s are still super valid.

I hope the earbud world gets a revolution like the IEM world has blown up. I'd love to see some new driver combos, like a 15mm planar driver or some EST's. Also maybe some new shells that use the standard apple earpod shape, which everyone universally agrees is a better fitting style of earbud.
Welcome to the FF3 club, mate!

Spot-on impressions as well. Very glad to hear that FiiO has done something about the cable. Does it keep memory and curl upon itself after rolling up?
It coils up just fine and stays in a nice little ball, but as soon as I uncoil it, it goes completely straight. The cable is very relaxed
Can you compare mx500, yincrow x6, or farreal irish2. on soundstage

Launched in June'2022, The FF3 is an earbud launched by FiiO. FF3 comes with a 14.2mm dynamic driver with dual cavities. FiiO promises this to be a great performer and carries the FiiO Signature tuning.

Disclaimer: @FiiO had sent me a review unit for my impressions & views. The opinions below are based on my experiences with the unit and my own.



Let's quickly dive into what the FiiO has to offer. The FF3 carries some new DRUM like bass cavity and a bass enhancing flute-type design.

FiiO FF3 Sound Impressions in Short:


Bass is where FiiO had put much emphasis and likewise the earbuds come with quite a punchy bass performance. There are some details coming from the sub-bass region, but the mid-bass is quite prominent and packs quite a bit of punch. In tracks like: "Fools Paradise (LP Version) – Donna Lewis" and "Chocolate Chip Trip - Tool" you can feel the mid-bass puch & slam is quite prominent while the sub-bass is underwhelming.


The midrange is quite a bit recessed on the FF3. However, there is good amount of muscle and texture and the instruments sound very lively and enjoyable. Vocals seem good and both male and female vocals come with ample amount of details and feel very real. Transients are also good. In tracks like: "Anchor - Trace Bundy", "A dog named Freedom – Kinky Friedman" and "Ruby Tuesday – Franco Battiato" though the midrange is enjoyable, but you feel a bit left out and long for more.


The treble carries the typical FiiO signature which some people may like - unfortunately I don't. It has few peaks here and there and may get quite piercing in some cases specially the Cymbals. This can be realized from tracks like “Chocolate Chip Trip – Tool”.


The Staging capabilities of the FF3 is the quite good and above average for price range. It comes with good amount of width, height, however, depth felt lacking a bit. Tracks like: “The Secret Drawer – Bela Fleck and the Flecktones” or “She Don’t know – Melody Gardot” or “Bohemian Rhapsody (live aid) – Queen” sound good & enjoyable.

Separation & Imaging:

Imaging is quite spot on and location of each instrument can be felt quite clearly on the FF3. Tracks like: “Rotterdam (Or Anywhere) - The Beautiful South “or “Hello Again - Howard Carpendale & The Royal Philharmonic Orchestra” just shine through. However, the separation is something you feel could be better.



The FiiO FF3 is a nice new earbud release from FiiO and aimed towards bass lovers. I'm quite confident that a lot of bass lovers will love this.

You got ff3 without a bud of 10$ to compare.
@kanett FF3 was my first ever ear bud tryout ... I'm an IEM guy mainly

The vast majority of earbuds will graph with weak bass without foams on--barring the ones that are closer to IEM style. When you put the foams on these, they definitely have a very legit bass. Great buds and review! Glad I have a set of them.

It was funny as I was trying them out and about. I dont recommend my method of passive isolation but I actually use my IEMs and tried the FF3 by using them while I am driving to work. I know not safe but believe me my commute requires music or I will go bonkers. Basically the FF3 outdoors mimics that graph that Fiio provided. Bass just falls off a cliff.

I wanted to add earbudsvto my collection of headphones and IEM’s.
I was hoping if someone could give me some advice.
I can choose between a set of used EM5 for 110,- euro, a new set of FF3 for 119,- euro and a new FF5 for 139,- euro. Which one is the best for me to buy and why?

kind regards,
