There is also a user manual in English and ear tips in sizes S, M, L and XS.

With these accessories and components, FiiTii ensures you have everything you need to start using your HiFiDots right out of the box.


The FiiTii HiFiDots come with a case that exudes elegance, thanks to its metal construction and carefully crafted curves. The all-metal build gives the case a premium look, enhancing the overall aesthetics. However, it’s important to note that the metal construction contributes to the case’s weight, which is around 98g. While it may feel substantial, the weight adds to the durability of the case.

To access the earbuds, you simply need to press the button in the middle of the case, and it opens up to reveal the HiFiDots nestled vertically within. However, removing the earbuds from the case can be a bit cumbersome initially. With a little practice, it becomes easier to handle.

The earbuds themselves have a small footprint, even with their accompanying stem. Weighing just 4.2g each, they are exceptionally lightweight, ensuring a comfortable fit even during extended listening sessions. The matte finish adds a touch of sophistication, while the earbuds’ construction primarily consists of plastic, which contributes to their lightness.

One notable feature of the earbuds is the small LED lights housed around the perimeter of the face. These LEDs can display various lighting effects if configured through the accompanying app. This adds a touch of personalization and flair to the overall design.


The FiiTii HiFiDots feature touch controls that provide a comprehensive set of functions for easy playback control and management of ANC and Transparency modes. With a simple touch on the earbuds, you can play or pause your music, skip tracks, adjust the volume, and even answer calls without needing to reach for your device.

To further enhance the user experience, FiiTii offers a companion app that allows for some customization options. While the key assignment options are somewhat limited, typically offering volume control as one of the options, the app provides the ability to assign specific functions to the touch controls according to your preferences.

One notable feature of the FiiTii app is the custom EQ function. This allows you to tailor the sound profile of the HiFiDots to suit your personal audio preferences. By adjusting the equalizer settings, you can fine-tune the audio output to emphasize certain frequencies or achieve a balanced sound signature that suits your musical tastes.

In addition to sound customization, the FiiTii app also offers a lighting effect feature. When enabled, the earbuds can light up in sync with the music you’re listening to, adding a visually immersive element to your listening experience.

Moving on to the Transparency mode, the implementation on the HiFiDots offers a unique approach. While it doesn’t provide the same level of openness as some other earbuds, the voice or ambient sounds you hear in Transparency mode are still audible. 

One advantage of the HiFiDots’ transparency mode is that it effectively manages wind noise. Unlike some transparency modes that tend to amplify wind noise, the HiFiDots strike a balance and ensure that wind noise is not overly emphasized, resulting in a more pleasant listening experience in outdoor environments.

FiiTii HiFiDots: Connection

Equipped with the latest Bluetooth 5.3 technology, the earbuds offer fast and stable pairing with compatible devices. During my testing, I found that the connection process to my smartphone was quick and hassle-free. The HiFiDots pair as a single unit, simplifying the setup and ensuring a straightforward user experience.

I was particularly impressed by the absence of any connection issues during my usage of the HiFiDots. The wireless connection remained stable and consistent, allowing me to enjoy uninterrupted audio playback.

One notable feature of the HiFiDots is the ability to use either the left or right earbud independently. This means that if you prefer to wear only one earbud for certain activities or if you want to share your earbuds with someone else, you have the flexibility to do so without any limitations.

Additionally, the HiFiDots support multipoint pairing, allowing you to connect them to up to two devices simultaneously. This feature is especially convenient if you frequently switch between devices or use your earbuds with multiple devices at the same time. With multipoint pairing, you can seamlessly switch your audio inputs between devices, enhancing the versatility and usability of the HiFiDots.

FiiTii HiFiDots: Sound quality

The FiiTii HiFiDots truly shine when it comes to their audio performance, thanks to their exceptional driver configuration and advanced technologies. The earbuds boast a bass dynamic driver with an impressive 10mm size, accompanied by a double-layer diaphragm structure made of PU+DLC (polyurethane and diamond-like carbon). This construction allows for increased magnetic flux, resulting in powerful and impactful bass reproduction.

In addition to the dynamic driver, the HiFiDots feature two balanced armature drivers that are exclusively customized for them. These drivers are strategically positioned closer to the opening of the sound tube, minimizing treble loss and ensuring a clear and well-blended audio profile across all frequencies. The meticulous design and positioning of these drivers contribute to the earbuds’ excellent audio performance.

To further enhance sound quality, FiiTii has implemented an advanced Passive Crossover processing technology. This unique technology ensures a powerful and well-balanced performance across all frequency ranges without producing any divided frequencies. The result is a cohesive and engaging sound signature that remains exciting and fun to listen to.

The HiFiDots offer a well-balanced sound signature. The bass and sub-bass frequencies complement each other, delivering a deep thump and punch without sounding bloated. While not classified as bass-heavy, the earbuds extend their low-end response when necessary, providing an immersive bass experience.

Moving to the mids, the HiFiDots deliver detailed and smooth vocal reproduction with a hint of warmth. Vocals, especially female vocals, are crisp and enjoyable, adding a layer of richness to the overall sound. The treble frequencies are sufficiently bright without becoming sibilant or harsh. Similar to the bass, the treble is well-controlled and only emphasizes when needed, resulting in a balanced and pleasing high-frequency response.

The FiiTii HiFiDots provide a pleasurable and engaging listening experience across a wide range of genres and musical preferences.


The FiiTii HiFiDots use active noise cancellation (ANC) to provide an immersive music experience by effectively canceling external noise. The earbuds utilize precise soundwaves to counteract ambient sounds, resulting in exceptional noise reduction of up to 47dB.

Whether you find yourself in a bustling and noisy environment or seeking moments of tranquility, the FiiTii HiFiDots ensure uninterrupted audio immersion. The adaptive active noise cancellation capabilities intelligently adjust based on your surroundings and the placement of the earbuds. This personalized approach to ANC ensures an optimal listening experience that is tailored to how you wear the earbuds.

Furthermore, the HiFiDots offer three different ANC modes: mild, strong, and transparent. By simply pressing and holding, you can easily switch between these modes to customize the level of noise cancellation according to your preferences and the specific environment you’re in. This flexibility allows you to adapt the ANC settings to your liking, whether you prefer a subtle reduction of background noise or a more robust cancellation.

The transparent mode is particularly noteworthy, as it allows you to stay aware of your surroundings without removing the earbuds. This mode enables ambient sounds to pass through, making it convenient and safe to use in situations where you need to remain attentive to your environment.


The FiiTii HiFiDots are equipped with efficient batteries that provide a satisfying amount of listening time. Each earbud houses a 35mAh battery, allowing for up to 6 hours of continuous playback on a single charge. This battery life aligns with the expected standard for earbuds of their size and functionality, ensuring that you can enjoy your music or podcasts without interruption.

To further extend your listening experience, the FiiTii HiFiDots come with a Charging Case that features a 460mAh battery. With this additional power source, you can enjoy an impressive total of 30 hours of playback before needing to recharge the case. 

During my personal usage of the HiFiDots, I found that the battery life exceeded my expectations. This allowed me to enjoy extended periods of listening without worrying about running out of power.

The case’s metal construction enhances durability and aesthetics, although wireless charging is not supported.  To recharge the case, you will need to use the provided USB-C cable for a wired connection. 

One notable feature is the quick charge functionality of the HiFiDots. By charging the earbuds for just 10 minutes, you can enjoy an additional 100 minutes of listening time. This is particularly useful when you’re in a rush or need a quick power boost before heading out.
