New Redmi AirDots S 2020 (Xiaomi Mi True Wireless Earbuds – Basic S) review

If you are looking for True Wireless Earbuds (TWS) but don’t know where to start, then without spending much money, one of your best bet is Xiaomi’s Mi True Wireless Earbuds – Basic S (also known as Redmi Airdots S). These wireless Bluetooth earbuds are an iteration to the Redmi Airdots which I reviewed last month.

If you are in a hurry, here’s what we liked and didn’t like about the Airdots S.

TL;DR: Pros and Cons

What We Liked

  • Good sound quality
  • Dual-earbud mode support
  • Low latency game mode
  • Great price point ($30)

What We Didn’t Like

  • Lack of multi-device support
  • Confusing branding across markets

There isn’t much difference between the Airdots and these Airdots S in terms of design and even specs. Xiaomi has made very slight changes to the Airdots S an upgrade is almost not justifiable.

Both earbuds have a similar in-ear form-factor and come in Black color variant. They also sport Bluetooth 5.0, the same battery capacities of 25mAh (per earbud) and 350mAh for the charging case charged through MicroUSB port. In addition to supporting DSP/AAC/SBC codecs, both earbuds use the REALTEK RTL8763BFR master chip and are powered by 7.2mm dynamic. Each earbud also sports a multi-function button. The differences are in how the earbuds pair and what Xiaomi calls “Game Mode”.

Pairing and Connectivity: Dual-Earbud Mode

When you are pairing the Airdots S, remove both earbuds from the charging case simultaneously and wait 2-3 seconds for the earbuds to automatically connect to each other. Wait for the indicator light on the left or right earbud to blink white and then search for “Mi True Wireless EBs Basic S” on your Smartphone/tablet/PC. Tap on them and they’re instantly paired with your device.

Now, notice the differences in pairing between the older Airdots and newer Airdots S. The older Airdots use a master-slave connection method to pair; first, the right or left earbud is connected/paired with your phone as Mi True Wireless EB Basic_R or Mi True Wireless EB Basic_L” respectively and then the other earbud now connects to the one that’s successfully paired with your phone! That’s one annoying aspect I find with the older Airdots.

The newer Airdots S use what Xiaomi calls “Dual-Earbud Mode”. When pairing, you’ll see only a single name “Mi True Wireless EBs Basic S” and when they’re paired with your phone, both earbuds right and left are connected simultaneously with your phone.

Now you can still switch between single and dual-earbud mode if you wish to. In single mode, you can still use one earbud right or left at a time. To do that, place one of the earbuds back into the charging case and close its lid. The other earbud will automatically enter the single-earbud mode. To get back to dual-earbud mode, remove the earbud from the charging case, and the default configuration is automatically restored.

Low Latency Game-Mode

The low-latency Game Mode is designed specifically for gamers. Game-mode is meant to reduce delays in audio data transmission while you’re playing games. To enable game-mode, simply triple-tap the multi-function button. Xiaomi hasn’t said much about this Game Mode, so I decided to play Temple Run with the earbuds on just to test how responsive they are. Admittedly, I am not really a hardcore gamer, but I barely noticed a difference when playing the game with the phone’s speakers vs the Mi Airdots S on game-mode.

Price and Where to Buy

You can get the Xiaomi Redmi AirDots S from Gearbest at $30, from at $25, Amazon India (₹ 2,399), or at Ugx 180,000 from Odukar Store if you stay in Kampala Uganda.
