Design and houses

Xiaomi tends to be conservative in the design of the AirDots line, so these headphones have the same look and what changes, significantly, is the finish. All in plastic, AirDots 3 has a capsule shape and bulky structure that still reminds you of past generations. Buds 3 Pro also has a pill design, but it is smaller compared to AirDots 3 and bets on a more refined finish, with shine and pleasant plastic to the touch, which still resembles rubber.

In the tests of the Techblog, the two headphones proved decent in terms of comfort and, for those who practice physical exercises, Xiaomi added here protection against water and sweat — IPX4 rating.

The case follows the language of the headphones. They are cases with a rubberized look and the main differences are in the format, size and finish. The AirDots 3 accessory is simpler with no details, while the Buds 3 Pro is exquisite: it has glossy plastic inside, a sturdier cap and a matte finish. Both are equipped with a USB-C power connection.

Connectivity and features

In terms of connectivity and features, true Chinese wireless came to market with Bluetooth 5.2, technology that ensures stable connection and energy efficiency. In practice, they are able to deliver a fast pairing, they are not vulnerable when they are away from the cell phone and, at least in my tests, the headphones had no problem with delays, so the latency was very low.

The tracks being played can be controlled by the touch sensitive buttons. You can pause and play, skip to the next song and trigger the virtual assistant over there. Still, it lacked the commands that allow you to go back and control the volume directly through the headphones. For example, rival Edifier TWS1 Pro delivers this last feature.

Normal in the input category, Redmi AirDots 3 does not offer a dedicated app for EQ and headphone setup. Buds 3 Pro isn’t either, but the Chinese version, dubbed AirDots 3 Pro, has its own app. What happens, however, is that it is entirely in Mandarin.

Sound Quality and Microphone

We arrived at the most important issue. When looking at the sound, you can see that Redmi AirDots 3 has a full-bodied signature and Buds 3 Pro is fully balanced. For you to understand it better, it’s important to keep in mind that the first headphone emphasizes the bass, so the songs tend to be impactful with accentuated beats. Buds 3 Pro is not like that. It has dense bass that doesn’t explode in the ear, while the mids and highs remain balanced.

if we take Blinding Lights, from The Weeknd, AirDots 3 plays this song with remarkable vocals, the beats come alive and I even noticed noises around them. Buds 3 Pro has an open profile and does not generate as much conflict as its brother. There’s a lot of balance: the low frequencies aren’t that strong, the mids are clear and the highs are crystal clear.

And the microphone? The Bluetooth compression in AirDots 3 is pretty sharp in communication, but there isn’t that metallic look of cheap headphones. Now the Buds 3 Pro components perform better, the compression isn’t as strong, and in my tests they do well during online meetings.

Noise cancellation

In noise cancellation we have here significant differences, perhaps the biggest difference between them. The simpler Redmi AirDots 3 has only passive cancellation, that is, the headphone structure is responsible for the isolation and there is no embedded technology capable of shielding from external sound. Buds 3 Pro, on the other hand, does have active noise cancellation: the microphones and an algorithm work to muffle the outside sound.

AirDots 3, even without any technology, manages to create enough isolation to “remove” those everyday sounds (car, motorcycle and dog barking, for example). The 3 Pro, on the other hand, has a very good noise cancelling and, as I mentioned in its review, it’s an efficient feature that some top-of-the-line don’t deliver.

In terms of battery and autonomy we have very interesting numbers. Xiaomi says the Redmi AirDots 3 has battery life for up to 7 hours of sound or 30 hours with the case. Buds 3 Pro has 6 hours of playback without active noise cancellation or 28 hours with the case. Interestingly, the company does not report autonomy with noise canceling turned on.

Let’s put it into practice: in my tests, AirDots 3 managed to play for 8h45min, a result more than excellent and above the combined. Buds 3 Pro, with the cancellation turned on, played for 5h53min, so a time considered ok, in my opinion.

In theory, it is clear that Redmi Buds 3 Pro is the best Bluetooth headset in this comparison for the simple fact that it delivers more features. But let’s not focus on that. In general, Buds 3 Pro and AirDots 3 are different products for different audiences. I see that AirDots is a device for those who are arriving now, that is, it is that gateway product for those who have never had a TWS. It is also cheaper on the market and can be a good option if you are short on cash.

The Redmi Buds 3 Pro, on the other hand, is for a more demanding audience looking for sound quality, premium design and active noise cancellation. It is a TWS for anyone who has been through AirDots and aims to acquire something more from now on. But that, of course, is not a rule. Now just analyze the one that will best suit you.
