The successor to the interesting true wireless stereo headphones (TWS) Buds 3T Pro is here. Xiaomi has just presented its flagship model Buds 4 Pro at the event held in China, and, on paper, they look very good.

These headphones arrive hand in hand with the sophisticated foldable smartphone MIX Fold 2 with a very clear purpose: to place themselves at the top of the portfolio of headphones that Xiaomi proposes to us. Some of the features that show that they aim high are its 11 mm diaphragm and its 360-degree surround sound technology, but if we stay only with this we will only be scratching the surface.

48 dB noise cancellation and up to 38 hours of battery life

Let’s start with what for us is the most important thing in a headset: its sound quality. During the presentation of these Buds 4 Pro Xiaomi spokesmen revealed that they use a diaphragm of 11 mm, so they bet on a slightly larger transducer than the one used by the Redmi Buds 4 Pro, which has a diameter of 10 mm. The purpose of this change probably responds to the attempt to extend the frequency response of these headphones.

In terms of noise cancellation technology the Buds 4 Pro, according to Xiaomi, also outperforms the Redmi Buds 4 Pro with some clarity. According to this brand, they manage to attenuate ambient noise by up to 48 dB, a figure that on paper is very promising in headphones of this type. In any case, we will not be sure about their performance in this area until we have the opportunity to test them thoroughly.

Another feature of these headphones that we cannot overlook is their autonomy. According to their designers, they offer an autonomy of up to 9 hours (we believe with noise cancellation activated), although using the charging case it is possible to stretch this figure to a very interesting 38 hours. There is no doubt about it, but, again, the most reasonable thing to do is to put these figures in quarantine until we have the opportunity to test them.

More interesting facts. They have IP54 protection, implement a low-latency connection mode, and, according to Xiaomi spokespeople, they offer a 360-degree sound that manages to credibly immerse us in our favorite music. Not all music genres fit, in our opinion, with this surround sound technology, but it is worth giving it a try so that each user can decide whether it convinces him or not.

Pricing and Availability of the Xiaomi Buds 4 Pro

These headphones have just been launched by Xiaomi in China for 999 yuan. At the moment, this brand has not revealed if it will arrive in the international market, but as soon as we know we will tell you.
