I’ve been on a bit of a roll with the budget true wireless earbuds lately, so I was up for the challenge when FiiTii asked me to review their HiFiAir TWS ANC earbuds.

First – let’s get the pronunciation out of the way. It’s pronounced “Fee-Tea”.

It’s a tough one for FiiTii (mifo earbuds), they have followed closely behind the Donner Dobuds One and the KZ VXS true wireless earbuds, which, as I have already reviewed, really impressed me at the $50 to $70 mark. 

That’s not to say that I wasn’t expecting good things from the FiiTii, but there was a little bit of an uphill start to our relationship.

A good effort with comfort and build quality holding up pretty good sound.

The FiiTii are a good set of true wireless active noise-canceling earbuds, but they are in a very crowded market, with increasing competition over the last year.

The build quality and battery performance is good. The comfort is also good, and the sound is also just good. I definitely think if you can get them with a coupon, they make good buying.

First impressions

As I’ve said in many of my previous reviews, I don’t like it when companies create excessive packaging for the sake of creating a more elevated experience. These mifo Earbuds branded as FiiTii have done a great job of keeping it tight, with a tiny package that packs only what you need.

There is a slightly retro feel to the design elements of the FiiTii, especially the case, but it still has all of the mod cons, like battery indicator LEDs, and LEDs on the earbuds themselves. 

When I first pulled them out of the case, they still had the plastic seal around the edges, which I’m guessing ensures that they not only arrive in perfect condition but aren’t accidentally activated in transit, causing the battery to go flat.

Build quality

The build quality is good, dare I say very good. 

The molding on the earbuds has a really nice curvature, and the design is well thought through. 

I’m not a big fan of triangles, but once they were in my ear, I was appreciative of how they fit. 

And, when looking at them in my ears, both head-on and in profile, they have a really nice, low-profile fit, and don’t stick out too far. While the styling of the case might be a little retro, it is well-built.

Tech specs

These have Bluetooth 5.2, active noise-canceling, have a low latency mode, which will be interesting for gamers. 

They have a mono and dual phone call function, and you can have one earbud at a time. 

They have touch-sensitive external surfaces for controls and are IPX7 waterproof, so these would be great in any sporting or outdoor endeavor. 

IPX7 means you can immerse them for short periods of time, short being up to 30 minutes-ish. Not that’s I’d try it but they might survive your washing machine.

In the box, you get the charging case, the two earbuds, a manual, and three spare sets of silicon ear tips, small, medium, and large (a total of 4 silicon tip as they come fitted with a set also).


I definitely feel like I need to call out the comfort of these because I was really surprised at how nicely they fit and sit in the ear. But, they do feel almost too small in my ears.

The lovely curved design is a great shape for how your natural ear is shaped, but the thing that did surprise me is, while I normally stick with the medium fitted silicon ear tips of most budget true wireless earbuds, the medium on the FiiTii HiFiAir just felt a little too small.

I had to push the earbuds, or pull them, quite low in my ear to seal my ear canal, and even then, the bass was lacking, and I was losing a lot of sounds. 

I swapped out the HiFiAirs medium tips with the large ear tips, which were a perfect fit for me, and created a great seal. 

It was then that the bass came to life, and I could hear the full soundscape. They really are light, and I managed to wear them for probably two and a half, three hours before feeling like I wanted to take them out of my ears.

Even still, I find myself having to adjust them to get that seal back when I put them in, even with the larger ear tips. 

I wonder if I could swap the tips out for some Comply or similar….hmmm….

Active noise cancellation

There are three modes on the FiiTii HiFiAir.

  • One is a light active noise canceling
  • One is transparency mode
  • and the last one is a high active noise-canceling mode

These can be activated by pressing and holding on either of the earbuds for at least two seconds, and there is a voice prompt that tells you what mode you’re in.

Personally, I found it helpful that it was telling me what mode I was in because it wasn’t always clear. 

It’s quite a subtle change between the three. 

The active noise canceling is effective for consistent and ongoing white noise around you, but I found that voices cut through quite clearly, and in fact, when all of the other noises were gone, thanks to the active noise canceling, it’s almost like the voices became more prominent. 

It wasn’t a significant issue for me, and I do tend to work in open office environments, but overall, the active noise canceling will probably not score too high on the review metrics for this unit.

The natural sound isolation was good though, which was enough for me.

Sound quality

I don’t know why I always start with sound quality near the end of my reviews, but there you have it. 

As I previously mentioned, I have come off the back of reviewing some pretty decent-sounding true wireless earbuds around this price. 

I would put the HiFiAirs in a similar bracket to the Ugreen X6. I would put them above the xFyros, and definitely in a similar space to the Black Shark T1s.

The bass is there. The problem with all the frequencies is that they do tend to hit you all at once. There’s not a lot of sound separation between each of the frequencies, so, bass, mids, and treble kind of roll in together but that can depend on what you deliver to them.

There is quite a full sound to them, and it definitely feels like someone pushed the bass frequencies up a little bit on the mastering desk when these were being tuned. 

It’s not unpleasant, and probably typical, as I say, of many other budgets’ true wireless earbuds, but over time, it lacks any excitement and doesn’t have any particular acoustic nuances to make you feel like you’re enjoying the kick drum or even the bass drops of other music you might listen to. 

You can pick up some nice tones on some tracks but on the whole, the bass is pretty solid and consistent.

The mids and trebles equally aren’t lacking.

Mid frequencies 

I would say there’s quite a flat line across how all of the frequencies, bass, mids, and treble, interact with each other. 

The bass is definitely a little bit on the upper end, but, like the bass, the mids and trebles don’t stand out so much.

The mids have a slightly warm or what I call the ‘cardboard’ edge to them.

They’re not particularly bright and sparkly, or rich and detailed. But they’re less than $50 so let’s not be silly.

That isn’t to say that they aren’t there. Vocals definitely come through. 

You can hear everything that would normally sit in the midrange, and nothing sets particularly too far back, so in that regard, I wouldn’t criticize ’em for being too V-shaped.

Treble sounds

Treble is a little bit light for my tastes.

There’s almost like there are no lower treble frequencies or upper mid frequencies that fill that space, but the mids still run into the treble without too much of a gap in the soundstage. 

I know that sounds like a contradiction but it’s almost like the bass runs constantly and fills all the gaps so you don’t notice as much. 

They’re definitely quite obvious, but not particularly acoustic in nature.

Overall sound quality

So, the overall sound quality is good. It’s good at the price, and it’s good, not excellent. They’re comfortable, they don’t lack a bottom end, and they do represent all the frequencies well, with only a couple of exceptions. 

In terms of PRaT, or any excitement in the listening, they certainly seem to lack that zing and sparkle, and it would be nicer if the bass had a little bit more tightness to it.

While it feels like a review with some negatives, I really can’t be too negative on these. 

The battery life, case, build quality, comfort, and overall sound are good, and at a true wireless earbud that’s sitting at under $50, it’s hard to critique it too much.

I’d recommend this to people who are looking to do a lot of commuting, with perhaps a splash of gaming and movie watching. 

These would be really quite good for that, and I would recommend them if you are gaming on a mobile device that offers Bluetooth connectivity. 

With the competition being so tight, keep an eye out for a discount code, and I would really like to listen to the rest of the FiiTii range, as they have some very interesting other earbud models which I think probably stand up a lot taller than the HiFiAir.

Active noise-canceling will be OK for commuters. The transparency mode doesn’t really offer too much transparency, so once you get them in your ears, the natural sound isolation is pretty much going to take over.

I don’t bemoan the fact that it’s lacking a USB-C charging cable, as I already have plenty of those cables, but it’s worth noting that this does not come with a USB-C cable if you’re expecting that. 

And, to be honest, it’s probably better for the environment than they don’t.
