Many of you regular readers will remember that I reviewed the FiiTii Hi-Fi Air earbuds a while ago. This is the second generation of the Hi-Fi Air, which has simply been dubbed Hi-Fi Air 2 from FiiTii.

The original FiiTii Hi-Fi Air didn’t impress me, but they were musical enough for the price that they were an acceptable budget true wireless stereo (TWS) earbud. 

It was the kind of earbud that I didn’t expect to hang around very long, and I wasn’t really sure if FiiTii would continue its production.

As a brand of Mifo, I thought that the overall offering wasn’t strong enough in a crowded market to allow it to continue.

Turns out that I was more than wrong, and Mifo and FiiTii have continued to go from strength to strength, and the Hi-Fi Air 2 has certainly taken a lot of learnings from its first go in the true wireless earbud space.

TL:DR;

The Hi-Fi Air 2 has also taken a different approach to drivers, this time incorporating a dynamic driver and a balanced armature driver along with first-class Bluetooth support and pretty decent battery life.

I have to say that of all of the true wireless earbuds that I’ve reviewed, these probably come closest in terms of form factor and size to Apple AirPods Pro. In saying that the fit isn’t quite as natural, but it’s not too bad.

Tech Specs

Looking at the tech specs of the FiiTii Hi-Fi Air 2, you’ve got a frequency response of 20 to 20,000 kilohertz.

You’ve got Bluetooth 5.3, which supports pretty much every Bluetooth audio protocol you can name. 

It has the benefit of a 12 mm dynamic driver, which is about 2 mm larger than your average earphone, which tends to gravitate towards the 10-mil driver size.

The addition of the balanced armature gives the FiiTii Hi-Fi Air 2 a lot more opportunity in the way it’s tuned.

The battery life is around five hours, and you can do an additional four or five charges in the case giving you another 20 to 25 hours.

This, of course, depends on what kind of active noise canceling mode you’re using as strong noise canceling will reduce usage closer to the four-hour mark.

Full charge time isn’t bad – around an hour for the earbuds and about 1.5 hours for the case.

Bluetooth codexes are AAC and SBC. The charging cable is a USB-C, and if you’re thinking of using these for sports and outdoor activities, then you’ve got a waterproof grade of IPX7.

From the specifications listed, the FiiTii Hi-Fi Air 2 looks really good in terms of what’s printed on the box – first-class Bluetooth, active noise canceling, dual hybrid drivers, and a 12 mm dynamic driver.

All of these things should really build to what you’d expect to be a pretty great sonic experience.

For me, it didn’t quite reach those highs, but then once we throw in the price, I think we can make some allowances, which I’ll go into more in a second.

Comfort

The comfort on the FiiTii Hi-Fi Air 2 is very good, although I’d recommend trying as many different silicone ear tips as possible to get the best fit.

The medium tips in the KZ range and the sure [SP] range tend to fit me on the first go, but with the Hi-Fi Air 2, I found the medium to be a little bit small. I’ve persevered with them because as long as you give them the right twist at the right angle, you can get a really good seal.

They’re very light, and the external touch control surface on the outside of the earbuds is very easy to make contact with. I didn’t find myself getting frustrated with a lack of responsiveness from the touch controls.

They’re non-obtrusive and light in the ear in a way that you feel relaxed with them. I definitely feel like they’re the kind of earbuds you could wear for a long time without feeling any discomfort.

Audio Fit

As I mentioned above, the medium ear tips feel just a fraction too small for me, but I’ve persevered with them because I think that they’re better for my ears than the large ones.

The audio fit in the FiiTii Hi-Fi Air 2 is great. 

If I were doing a lot of outdoor exercises or even at the gym, I’d probably level up to the larger silicone to create a slightly stronger feel. But when I’m using them at work, I use the minimum medium tips, and I find that these are the best for office listening.

You do need to twist them in such a way that they create that perfect seal. Unlike a lot of true wireless earbuds, if you do miss that seal, then you’re penalizing the earbuds from producing the best sound possible.

With these, even the slightest leak completely drains any bass response, even more so than similar true wireless earbuds that Sony or Apple might produce. 

So, the audio fit is all around pretty good.

Case

The charging case of the FiiTii Hi-Fi Air 2 is larger than that of the AirPods Pro, but not too large than any other true wireless earbuds you get.

What I like about the case is that it’s very much molded like a river stone in a way that the edges are smooth and round. This means when you slip it into your pocket, it doesn’t give the impression that you’ve rammed a big square piece of Lego in there.

There’s a nice sculpting to the case, which I think is a credit to FiiTii in terms of design.

Sound quality

I really wanted to love the FiiTii Hi-Fi Air 2. 

I wanted them to punch above their price range, and make the most of their hybrid design, but I’m not sure they reached the heights. I’m not sure that I was very realistic about my expectations.

Bass

There’s no doubt that the tuning of the FiiTii Hi-Fi Air 2 feels a little V-shaped. 

The bass response feels like it has a bit of a boost somewhere between the 10 and 15 DB if I was to hazard a very random guess, which numerically is significant in DB. Overall it does inflate the bottom end of the earbuds.

It’s certainly not unpleasant. It’s more of a full rich round sound.

Some reviewers have commented that the bass is tight, but I wouldn’t agree with this. I’d just say that the bass is quite bold and fills out the bottom end of any track that you add to it.

It’s not particularly inflated in the sense that it doesn’t overpower the other frequency ranges, but you’ll want to enjoy some bottom end on this. I think the average consumer is gonna love how the bottom end sounds.

Midrange

The midrange sits back a little bit. You get some jingle jangle around the guitar vocal frequencies, but this is where I love to see earbuds come to the fore.

I can’t penalize them for anybody that’s just looking for affordable earbuds, but if you’re an audiophile looking for a budget pair of true wireless earbuds, then the FiiTii Hi-Fi Air 2 may not be ideal if you love a good mid-range.

Treble

The trebles come in clean enough, but overall the mids and trebles together sound a little bit like there’s a piece of paper between me and the sound itself. 

It’s incredibly minor. It’s a harsh criticism, but they’re not as fresh and bright as I think they could be considering the driver configuration that they have to play with.

General Sound Conclusion

Overall, if you add the overall frequency response across the range, the FiiTii Hi-Fi Air 2 offers good quality. 

You can stick them in your bag and take them on the train during your commute. They’re great for a quick listen in class and would suit students or anyone else on a budget who wants something that looks good, feels good, and sits in the ear while providing a more than decent sound.

Active Noise Canceling

Of all the criticisms I have of the FiiTii Hi-Fi Air 2 earbuds, it’s the noise canceling to the point where I’m not sure that they needed to bother.

I’ve compared these with a whole range of other true wireless earbuds with active noise canceling that I own, and I just didn’t feel that there was enough in it.

There are three modes. There’s light active noise canceling, no noise canceling, and strong noise canceling.

There are very minor changes to the audio frequency with each change, but there are also very minor changes to the amount of external noise that you can hear.

I wouldn’t consider them a frontline runner for their noise-canceling features and would focus instead on their ability to perform just as a true wireless earbud.

Final Thoughts

Summing it all up, my conclusion for these earbuds has been iterated through this post a few times.

For around $50, even a little bit more, the FiiTii Hi-Fi Air 2 offer great build quality, good comfort, and decent sound.

The build quality and responsiveness of the touch controls, in addition to the overall fit and comfort alone, make these earbuds great value for money. Of course, you’re buying it for how it sounds, and it definitely sounds good enough for $50.

While they’re not sufficient for audiophiles, these earbuds should find a home in the hearts of many general consumers. 

And even though the active noise canceling didn’t quite work for me, this doesn’t penalize them as being a great choice in the under $100 cute [SP] wireless earbud space.

A big bottom end and a general ability to work with most genres of music mean that the FiiTii Hi-Fi Air 2 will be an easy pickup-and-go pair for anyone out there.
