Design of the realme Buds Air

In terms of appearance, the realme Buds Air 3 headphones maintain the shape of the realme Buds Air 2. The cups have a very elegant finish (we love the blues), as does the case. The texture of the cups and case is excellent and reduces fingerprint marks. The package comes with the USB-C cable for charging and additional tips to ensure a good fit.

The build quality is remarkable for an inexpensive in-ear headset. In addition, they are IPX5 certified against splashes or sweat. You can wear them to the gym without any problems, as they also fit securely. Each cup weighs only 4.2 grams and you forget you are wearing them after a few minutes.


The realme Buds Air 3 work with Bluetooth 5.2 technology. The wireless range is wide and works without problems. They are easy to use Bluetooth headphones and you can operate different functions with the touch controls on the cups. Of course, real phone users get a few extra options to facilitate the synchronization process, but they are great for any device.

They support simultaneous dual synchronization. This means you can keep them connected to a tablet to watch movies and to the phone to answer calls. They are also ideal for gaming. The latency of the realme Buds Air 3 is only 88ms, which is remarkable for a cheap Bluetooth headset.

With the Link application for the realme headphones, you can access various necessary functions, such as customizing the controls, multiple connection and changing the active noise cancellation mode. It also allows you to customize and create settings to get the sound style that's right for you. Every user of the realme Buds Air 3 can enjoy a unique and optimal experience.

Battery life

In normal mode, the batteries of the cups yield up to seven hours of continuous playback. With noise cancellation active, the capacity drops to about 5.5 hours. In addition, the charging case/charging base provides you with additional charges for a total of 30 (ANC OFF) or 22 hours (ANC ON).

The case of the realme Buds Air 3 is charged with the USB-C cable. The total charging process takes approximately 1 hour, and with only 10 minutes of charging you can use them for almost two hours.


Active noise cancellation and certifications

Noise cancellation technology is the best feature of these True Wireless In Ear headphones. The realme Buds Air 3 can reduce up to 42 dB of noise, a unique capability in this price range. These realme headphones work with a dual microphone structure and the R3 chip to give you a really great ANC (for a budget headset).

The realme Buds Air 3 are the first in-ear headphones to pass the Rheinland certification for high performance noise cancellation. This agency was established in 1872, and functions as an agency that guarantees the quality and safety of equipment. Rheinland certification takes into account ANC capacity, efficiency, connection stability, latency and call performance.

In addition, the realme Buds Air3 headphones are also Golden Ear Selected Product (CGEC) certified, the first authoritative certification that objectively and subjectively evaluates audio equipment in the Chinese industry.

Most noise-cancelling headphones have problems with wind noise. However, the software of the realme Buds Air3, together with the Smart De-wind hardware technology, does a great job.

They automatically recognize the wind force, while an AI calculates and controls the wind pressure to reduce noise. Secondly, the De-wind structure allows air to flow through the cups and prevents turbulent wind noise.

In the same way, to ensure a completely noise-free experience, the microphones of the realme Buds Air3 also work with an algorithm that allows you to make calls with very decent clarity in any environment. Honestly, the ANC doesn't compare to that of the best noise cancelling headphones, but in this price range, it's great.

Sound quality

The noise cancellation of the realme Air Buds 3 is incredible, but fortunately they also offer good sound. We tested them by playing several songs of different music genres on Apple Music and were amazed with the performance.

They work with Dynamic Bass Boost (DBB) technology that allows the 10mm drivers in the cups to improve bass response. These ultra-real headphones also support Dolby Atmos, allowing you to enjoy virtual surround sound ideal for watching movies or series.

The bass response is excellent thanks to the large transducers. They show strength and good textures. They also maintain the same level of resolution and clarity at any volume level. The treble is not as good as the bass, but sounds decent.

The realme Buds Air3 are perfect for playing contemporary genres. The audio profile is nice, and you can also choose different sound styles with the application. The only negative is that they favor bass a lot, so they don't offer the most neutral or faithful audio.
