Redmi AirDots S VS Mi Air 2s TWS: Appearance Design

As the upgrades of their respective series, Redmi AirDots S and Xiaomi Air 2s TWS are no different from the previous generation of designs, completely retaining their previous generation of designs. But Redmi AirDots S and Xiaomi Air 2s are two different true wireless Bluetooth headsets from Xiaomi, and they are very different in appearance.

 

At first, let’s talk about the Redmi AirDots S TWS.

 

Redmi AirDots S is different from AirPods's piano-like paint in bright white, and the black Redmi AirDots S surface is frosted. The charging box is compact and light in shape and round in appearance. The front is only designed with the "MI" logo, without any elements that will cause visual redundancy. In addition, the Redmi AirDots S headphones are designed with in-ear design and are very small. The ear cap is made of silicone, soft and skin-friendly and not easy to fall off. The weight is only 4.1g, hardly feel any burden, and it is very comfortable to wear.

Different from Redmi AirDots S's ellipse round case design, the charging box of Xiaomi Mi AirDots Pro 2s is more square and closer to AirPods 2. In addition, the earbuds are also changed from the in-ear type to the semi-in-ear type. The Xiaomi Mi Air 2S weighs 4.5g per ear, which is slightly heavier than the Redmi AirDots S, but it feels almost unburdensome to wear. The semi-ear-to-ear design is also more convenient to operate and is not easy to cause miscontact.

 

Redmi AirDots S VS Mi Air 2s TWS: Sound Quality

In the aspect of sound quality, Xiaomi Mi AirDots Pro 2s has a built-in 14.2mm driving unit and special large composite diaphragm moving coil. In terms of hardware, it adopts a new architecture and carries out in-depth optimization. And LHDC Bluetooth decoding is optimized for the MIUI system, supporting LHDC 3.0, which can enjoy nearly Hi-Res level sound quality in the wireless state. In the video and audio process of the game, the mobile phone turns on the low delay setting, which can greatly reduce the sound delay and achieve sound and picture synchronization.

(NOTE: LHDC 3.0 is currently only supported on Redmi K30 Pro and Xiaomi Mi 10.)

 

Redmi AirDots S uses the in-ear design, which has an advantage over the open semi-in-ear design of Mi AirDots Pro 2s. In addition, most of the real wireless headphones on the market do not support bilateral calls. In voice calls, only the main headphones make sound, which can lead to unclear calls in a noisy environment. Redmi AirDots S cancels the master-slave connection, realizes bilateral calls, cooperates with DSP digital noise reduction, and effectively improves the call quality.

Redmi AirDots S cancels the master-slave connection, realizes bilateral calls, cooperates with DSP digital noise cancellation, and effectively improves the call quality.

 

Of course, because Redmi AirDots S does not support LHDC Bluetooth decoding, the effect is slightly lower than that of Xiaomi Mi AirDots Pro 2s when listening to music with Redmi P30 Pro or Xiaomi Mi 10.

 

Redmi AirDots S VS Mi Air 2s TWS: Latency Comparison

The Redmi AirDots S headset is equipped with the latest Bluetooth 5.0 chip, the data transmission rate is twice as fast as that of the previous generation Redmi AirDots, the connection is faster and more stable, and the new game low-latency mode makes it more enjoyable and smooth to play games.

 

When Xiaomi Mi AirDots Pro 2s is used with Xiaomi's phone, the in-game delay can be as low as 120ms. So that users can enjoy music, video, games, can have a more comfortable experience.

 

Overall, the latency of Redmi AirDots S and Mi AirDots Pro 2s is better in true wireless Bluetooth headsets at the same price. However, they all need to be paired with Xiaomi phones to achieve the best low-latency experience. If you are not using a Xiaomi phone, your latency experience may be similar to that of other ordinary real wireless headphones.

 

Redmi AirDots S VS Mi Air 2s TWS: Battery Life Comparison

In terms of battery life, the gap between Redmi AirDots S and Xiaomi Mi Air 2s TWS is very obvious.

 

The Xiaomi Mi Air 2S TWS comes with a charging box that supports Qi wireless charging and has a USB-C port at the bottom, which takes an hour to be fully charged. Music can be played continuously for 5 hours in a single ear, and if the Mi Air 2S TWS battery box is fully charged, it can play for a total of 24 hours (70% more than the previous generation of Mi Air 2).

 

Redmi AirDots S can listen to music continuously for 4 hours when both headphones are fully charged, and accumulate more than 12 hours of battery life when used with the charging box. So, in terms of batteries, it is clear that Xiaomi Mi Air 2S TWS is better than Redmi AirDots S.

 

Redmi AirDots S VS Mi Air 2s TWS: Price Comparison

At present, both, Redmi AirDots S and Xiaomi Mi AirDots Pro 2s are on sale in China. The official website of, Redmi AirDots S is priced at 99.9RMBMastore Xiaomi Mi AirDots Pro 2s and the price is 399RMB (there is no official announcement of the price in India for the time being). It is clear that Xiaomi Mi AirDots Pro 2s TWS is more expensive, after all, its battery life and LHDC 3.0 are better than Redmi AirDots S.

 

If you want to buy a long-lasting Xiaomi true wireless Bluetooth headset, then Xiaomi Mi AirDots Pro 2s must be the most appropriate choice. It not only has a 24-hour long endurance but also supports wireless charging function, which is very convenient.

 

And if you are less demanding on batteries and prefer something more comfortable to wear, then I recommend you to buy Redmi AirDots S. Because the Redmi AirDots S TWS is not only cheap, the ear-in design is comfortable and not easy to fall off, even sportswear is also supported.
