FiiTii HIFIDots TWS IEMs – Good Sonics, Alien Style Now 

FiiTii HIFIDots is a $199 USD pair of IEMS or in-ear monitors from a brand that changed the name of the company a few times, and the version we have today is interesting to say the least, as it comes with a good sonic quality, outstanding charging / transport case design, and with actually a good sound (the previous versions sounded quite colored and were hard to recommend). The comparison list for today will include other IEMs from the company, including the Sports & Outdoors Mifo S (169 USD), GravaStar Sirius P5 (139 USD), and Grell TWS1 (199 USD). 



While most companies out there are civil with the names, I would say the company that is now named FiiTii is downright outrageous, and it is hard for me to keep writing those names, FiiTii and HIFIDots with no space is just too much for me. This being said, the company has quite a few products under their belt and they were all made well, so we can excuse the marketing and naming for the products and the company, if they can deliver something that is made well and which works well. The IEM we have today is a TWS or True Wireless IEM with what I would consider the Alienware of TWS Bluetooth EArphones. It is just made well and looks like an alien tier of next-level Scifi. 

I’d like to thank FiiTii for providing the sample for this review, in exchange for my honest opinion. We are not receiving any incentive for this review and Audiophile-Heaven has no affiliation with FiiTii beyond this review. This review is a description of my personal experience.

Build Quality/Aesthetics/Fit/Comfort

Since this is a TWS or True Wireless Bluetooth IEM we need to start by saying that the connection is rock stable, and I had no signal dropouts, even when I moved in a room, over 5 meters away from the smartphone. To drive and power the FiiTii HIFIDots I’ve been using a collection of smartphones, and DAPs including Hiby R6 III, Samsung S23 Ultra, ASUS ROG 7, HUAWEI P30 PRO. Things work nicely, but the IEMS have a separate volume from the smartphone, so even if you max the phone, if the sound is too quiet, you can still add much more using the volume on the IEMs. The way they work is very different from most IEMs, and you have to learn how to use them. 

If it is not evident from the start, this is one of the most beautiful looking TWS or True Wireless IEMS out there, both the IEM shells and the transport / charge case. It is just gorgeous. The company promises that they have IPX7 water and salt resistance, which si great if you’ll be taking those to the gym. 

Happily, there is an app available for them, and if I dislike something strongly, it is having to install new software for everything, but you can easily find the FiiTii app on Android Store. The app does not see the IEMS at the point I am writing this review, but as with most things software, you shouldn’t fear this and should be able to get it running after the company updates it. 

The comfort is actually excellent, they are small, light, and snappy. The smartphone reports on the remaining battery a bit too accurately, it shows the remaining battery life in 1% increments, which is different from most IEMs that show 10% at most, some showing the remaining battery life in quarters. The battery life is not the longest, and the company is honest about what you’re likely to get from the HIFIDOTS, and they have around 5 hours with no ANC, and around 4 hours with ANC or Transparency mode turned on. The case takes 1 hour to charge, and the earbuds take 45 minutes to charge. From what I could test, the case has 5-6 extra charges. 

There is an ANC protocol implemented in the FiiTii HIFIDOTS, it does not degrade the sonic quality of the IEMs, but it is not very strong, and the company promises around 47 dB of passive noise isolation, but HIFIDOTS have around 30 dB at max, and 25 dB with no ANC. The aptX Lossless codec also does not seem to work with any of my sources, and I am locked to using SBC as there is no LDAC protocol available, but that is actually ok, because they sound quite good with SBC too. The call quality is awesome, HIFIDOTS have a good microphone quality, have a good max loudness and the person on the other end could hear me clearly. 


Sound Quality

As I mention from the beginning and the name of the review, those actually have a good sound, and that is not tied to the protocol that is being used, it is the DAC , AMP, Drivers and combination of those that actually results in the improved sound, along with the inner design of the earbuds, and the better tips. The tips are of an excellent quality, have the right stickiness to offer good support for the light earbuds. The best music styles for the FiiTii HIFIDOTs are Pop, EDM, Dubstep and ACG, and they handle rock, metal and acoustic music worse, but they are sublime for bass-heavy styles and music where you want things to be punchy, dynamic and vivid. The sound is bassy, bold, a thick style of U-Shaped sound, with a heavy bass, recessed midrange, and a sparkly, airy treble. With most FiiTii earbuds, the treble was too shy, it rolled off early, and the sound was not detailed enough for the price the products had, but the new HIFIDots actually have a good detail and clarity for the price. 

The bass is deep, lush, full and super powerful. In fact, it is so strong, you could say it overpowers the other frequencies a bit, and creates a bit of bleed and veil into the midrange, the body the mids inherit from the bass being more than what is absolutely neutral or natural. This being said, this kind of signature and tuning works really well for electronic music styles, only being unnatural for rock and metal, where a brighter, more neutral presentation is desirable. Pop music in particular works super nicely with the FiiTii HIFIDOTS. The bass reaches as low as 20 Hz in the lows, and it stays elevated all the way until 200 Hz, which is huge, and the whole bass is big, large, moves naturally in speed, and has a long decay. The transients of the bass are sloppy and slow, textures soft, but with no distortion regardless of the volume. 

The midrange is recessed, but is handled by a different balanced armature driver from the bass, and it is far sharper, it has hard transients and textures, the clarity and detail is very good. The difference in presentation is noticeable and it takes a while to get used to having such a fast midrange after a much slower and sloppier bass. We have good definition, dynamics and a wide soundstage in the midrange, with a good instrument separation and clarity as well. The voicing is done in such a way that the lead voices always sound a bit close to the listener, guitars, pianos and most instruments are placed very far away from the listener, while drums are placed really close to the lead voices, and the cymbals are scattered all across the stage, filling the soundscape with sound. This kind of tuning makes songs from Lady Gaga and Kesha super interesting, same for songs by Mori Calliope, but you hear the coloration quickly with The Offspring or Metallica. 

The treble is sharp, has a different transient profile, and the driver is much softer than the driver for the midrange which keeps the sound fatigue-free despite a bright and sharp treble. We have outstanding clarity and precision for the treble of a bluetooth earbud, and for pop songs, this is absolutely spot-on with what you’d expect them to sound like at their best. It is interesting that each driver has its own very unique and distinguishable sound. Simpler songs with fewer instruments sound better, and anything that you hear on TikTok, Instagram reels or anything extra popular, will be delightful. Complex music with orchestral bits or complex metal are handled with the mentioned colorations, which will be an acquired taste, but not a bad mix. All in all, the sound is really good, and for a bluetooth IEM, it is quite capable, offering a presentation that is as fun as most high-end IEMs, being comparable in detail, resolution and clarity to HIFIMAN Svanar Wireless, with the sloppier bass of the FiiTii HIFI Dots being preferable for listeners who want a bigger bass. Just make sure to disable all sound enhancements on your phone before connecting the HIFI Dots as those TWS Earphones sound best if left at their default state. 



FiiTii HIFIDots vs GravaStar Sirius P5 (199 USD vs 139 USD) – The build is futuristic for both, but P5 is plasticky for the earbuds, they feel light, but also somewhat cheap, while the transport case of the HIFI Dots will offer them better protection during transport, it feels better in hand, and they are a better pair of bluetooth earphones in the comfort, where the earbuds themselves sit better in my ears thanks to their smaller bore size. Sonically, HIFI Dots wins in every aspect, they sound much cleaner, deeper, more detailed, more crisp and have a better impact, with more treble energy and sparkle, while P5 is far more rolled off, smoother, warmer, but also considerably less detailed. The winner is the HIFI Dots easily here, especially when you factor in the fact that they have ANC which does not degrade the sound, while P5 does not. 

FiiTii HIFIDots vs Sports&Outdo Mifo S (199 USD vs 169 USD) – Mifo S and HIFIDots are made by the same company, and you can see that both are made for the looks first, but Mifo S did not impress me that much with the sonics, and if you can afford the extra 30 USD for the HIFI Dots, the sound is considerably more detailed, with a better treble extension, better clarity, more resolution and just generally a more pleasing experience. The ANC is really good on the HIFI Dots, and the entire IEM is a high-end product with a really fair price tag, while Mifo S is not as hot of a deal when comparing them directly. 

FiiTii HIFiDots vs Grell TWS1 (199 USD vs 199 USD) – The only IEM in my list that can actually compete with the HIFI Dots from Fii Tii is the Grell TWS 1, and starting with the ANC, both have no signal and sound degradation when the ANC is on, both are good at ANC, although the ANC is stronger on the TWS 1. The comfort is actually a bit better on the HIFI Dots which is smaller and fits better with my ears, but the sound is a bit more detailed, cleaner and more punchy as presented by Grell TWS1. Here, the result is less clear, I would grab the TWS1 if you have larger ears and generally have good comfort with larger IEMs, and want the better sound, since they have a similar tuning, but I would grab the FiiTii HIFIDots if you want a better looking product, with better comfort. 


Value and Conclusion

The price of the HIFIDots is not high, and for 199 USD, you could argue they are barely an entry-level to the audiophile world, but for a TWS or True Wireless IEM, they are quite expensive, as most of those bluetooth IEMs are much cheaper usually. The trick here is that those do provide one of the best build qualities available and look neat, and sonically they sound good enough to be worth the price, so the value is all there. Naturally, the naming won’t help them in the marketing department, but they provide a good product for the price. 

At the end of the day, if you’re looking for some of the best looking true wireless, bluetooth IEMs with a neat transport / charging case, good comfort, and for a really enjoyable sound, FiiTii HIFIDots gets everything right, makes you listen more and they are a good pair of IEMs that I recommend in 2024.
