Xiaomi Redmi Airdots 2 are some of the most popular wireless headphones in the budget segment, but many users do not know how to make the most of their physical buttons. Unlike the more expensive touch-controlled models, everything here is built on mechanical keys — and this is both a plus and a minus. On the one hand, the buttons do not respond to casual touch, on the other — their functionality is limited to factory settings.
In this article, we'll look at not only basic combinations, but also hidden features that the manufacturer doesn't always advertise, such as how to reassign actions through third-party apps, what to do if buttons stop responding, and how to avoid typical setup errors.
Basic button functions: what can be done without settings
By default, Redmi Airdots 2 supports a limited set of actions that are assigned to physical buttons, all of which work only when the headphones are connected to the device. If you press a button and there is no reaction, first check if the pair is active in the list of connected Bluetooth devices.
Main combinations:
- 🎵 Single tap (right or left earphone): play/pause of track. Works on most players, including Spotify, YouTube Music and a standard player MIUI.
- 🔊 Double tap (right earphone): next track. On some firmware, it can work as a "voice assistant call" (e.g., Google Assistant).
- 🔙 Double tap (left earphone): previous track, rare repeat of last track (depending on player).
- 📞 Retention 1-2 Seconds (any earphone): Accept/reject an incoming call. If the call is already coming, the hold will complete it.
Important: there is no way to adjust the volume directly from the buttons, which is one of the main limitations of the model, and there is no support for custom gestures, as in the more expensive Xiaomi Air 2 Pro or Buds 3T Pro.
The difference between left and right earphone: why buttons work differently
Structurally, the Redmi Airdots 2 has asymmetrical controls: the right earbud is considered the master, and the left is considered the slave, which affects not only the Bluetooth connection (the right earbud always connects first), but also the functionality of the buttons.
Key differences:
| Action. | Right earpiece | Left earpiece |
|---|---|---|
| Single tap | Reproduction/pause | Reproduction/pause |
| Double-push | Next track / voice assistant* | Previous track |
| Triple press. | Activation of voice assistant (on some firmware) | Not supported |
| Holding 1-2 seconds | Acceptance/rejection of a call | Acceptance/rejection of a call |
| 5+ sec retention | Resetting settings (only when the headphones are off) | Not supported |
*Depends on the version of the firmware headphones and smartphone model.
⚠️ Warning: If you notice that the left earphone has stopped responding to double pressing, try resetting through the right (hold 5)+ In 30% of cases, this is due to a software failure of synchronization between headphones.
How to Reassign Button Functions: Workarounds
Xiaomi does not officially provide any tools for customizing buttons in Redmi Airdots 2. However, there are several ways to get around this limitation:
- Third-party apps (e.g. MacroDroid or Tasker) allow you to create macros that fire when you press the headphone buttons, for example, you can double-press the left earphone to increase volume, despite the lack of such a feature by default.
- Firmware through ADB. For advanced users, there is an opportunity to change the configuration files of headphones, but this requires root rights on the smartphone and risks losing warranties.
- Use of players with customizable gestures. Some applications (for example, Poweramp) allow you to assign actions to the hardware buttons of the headphones directly in their settings.
Example of settings via MacroDroid:
- Install the app from Google Play.
- Create a new macro with the Media Button trigger → Headset Double Click.
- Choose Volume as the action. → Increase Volume.
- Save the macro and test it.
Check the version of the headphone firmware
Install one of the applications (MacroDroid, Tasker)
Set up access rights for the application
Create a backup of your current settings-->
⚠️ Note: Reassign buttons through ADB Or modified firmware can cause headphones to run unstable, including connectivity or sound issues. If you're unsure of your skills, it's best to limit yourself to third-party apps.
What to do if the buttons do not work: diagnostics and repair
If Redmi Airdots 2 buttons fail to respond, the problem can be both software and hardware.
- 🔄 Reconnect the headphones to the device: remove them from the list of Bluetooth devices and perform pairing again.
- 🔋 Check the charge: At a battery level below 10%, some features (like double-pressing) may not work.
- 🧹 Clean the mud buttons: Use a cotton swab dipped in alcohol to remove dust and fat.
- 🔧 Reset the settings: hold the button on the right earphone 5+ seconds before flashing red and white indicators.
If the basic methods did not help, the problem may be:
- 🔌 Oxidized contacts under the button (disassembly required).
- 🛠️ Damaged button membrane (frequent problem after falls).
- 🔄 Firmware failure (solved by flashing through the service center).
Critical information: If your headphones stop connecting at all after reset, don't try to sew them yourself. 90% of the time, this results in total loss of performance. Contact Xiaomi Service Center - repair warranty will cost less than buying new ones.
How to disassemble headphones for cleaning buttons
Hidden features: what buttons can do besides music and calls
Few people know, but Redmi Airdots 2 buttons can be used for more than just music control.
- 🎤 Voice Assistant Activation: On some firmwares, triple tapping the right earphone calls Google Assistant or Siri (depending on the device).
- 🔇 Switching noise reduction modes: if your smartphone supports MIUI 12+, Holding the button on the right earphone for 3 seconds may turn on / off the "Transparency" mode (missing external sounds).
- 🔄 Quick reconnect: If the headphones have already been paired with the device but do not automatically connect, double tapping both headphones simultaneously (within 2 seconds) initiates a reconnection.
- 🔋 Charge level check: when connected, triple tapping the left earphone will force the voice assistant to voice the remaining battery charge (does not work on all devices).
⚠️ Warning: Voice Charge Alert Function Only Works on Smartphones Xiaomi/Redmi/Poco firmware MIUI 11 And it's not available on other brands, like Samsung, iPhone.
💡
If you need to quickly turn off the headphones, but you do not want to take them out of your ears, just hold the button on the right earphone for 3 seconds – this will break the Bluetooth connection without completely turning off the device.
Comparison with other Xiaomi models: what you lost and what you got
Compared to newer models like the Xiaomi Air 2 SE Or Buds 3, Redmi Airdots 2, they play on the button functionality. SE support:
- 🔊 Volume adjustments directly from headphones.
- 🎵 Customizable gestures through the official Mi Earphones app.
- 🔋 Display the charge level of each headphone separately.
Redmi Airdots 2 wins in:
- ⚡ Autonomous operation time (before) 12 clockwork 5-7 new-model).
- 💪 Strength: Mechanical buttons are less prone to random pressing than touch buttons.
- 💰 Price: Even in 2026, it is one of the most affordable TWS-headphones with acceptable sound quality.
💡
If you’re critically interested in button settings, consider switching to Xiaomi Air 2 SE or later. If autonomy and reliability are the priority, Redmi Airdots 2 is a great choice.
