How to turn on noise cancellation on Xiaomi AirDots: detailed instructions with photos

Why is AirDots noise cancellation not working as you expect?

Xiaomi AirDots headphones (including Redmi AirDots 3/4 Pro, Mi True Wireless 2 and AirDots Pro 2) feature active noise reduction (ANC), but many users face problems when activating it. The fact that the ANC algorithm in Xiaomi budget models differs from flagship solutions (for example, Sony WH-1000XM5 or Bose QuietComfort).

If you expect total silence, like in studio headphones, Xiaomi AirDots is physically unable to do so because of the limitations of the hardware platform. However, the right setup of ANC can improve sound quality by 30-40%, especially in noisy areas. In this article, we will discuss how to turn on noise cancellation on different models, why it may not work, and what alternative ways to reduce noise exist.

Which Xiaomi AirDots models support noise reduction?

Not all AirDots headphones are equipped with ANC. The function is available only in the following models:

• 🎧 Redmi AirDots 3 Pro – Hybrid Noise Reduction (ANC + ENC microphone-wise)
• 🎧 Xiaomi Mi True Wireless 2 is the base ANC (low-frequency)
• 🎧 Redmi AirDots 4 Pro - Improved ANC level-set
• 🎧 Xiaomi AirDots Pro 2 / Pro 2s — noise-canceling

2. Touch and hold the touchpad on any of the headphones for 2-3 seconds.

If the problem persists, check the headphones on another device (such as a tablet or laptop). Sometimes conflicts arise because of the features of the Bluetooth stack of the smartphone (especially on iPhones or devices with custom firmware).

Alternative ways to reduce noise (if the ANC is weak)

If the built-in noise reduction is not good for you, try these methods:

• 🎵 Use uniform sound: Turn on white noise or natural sounds (available on Spotify, YouTube or specialty apps like Noisli) to mask external sounds.
• 🔧 Set up the equalizer: Increase the low frequencies (50–200 Hz) in the smartphone sound settings – this partially compensates for the weaker frequency. ANC.
• 🛡️ Buy a headphone case: Silicone pads (like Comply Foam) improve noise insulation by 15-20%.
• 📱 Activate. ENC For microphone: Redmi AirDots 3 Pro and later has a feature ENC (Environmental Noise Cancellation for microphone – it reduces noise when calling.

For maximum effect, combine ANC with passive noise insulation: correctly select the size of the earpieces and insert the headphones tightly into the ear canal.
