Setting up sensor control

One of the key benefits of Redmi Buds 3 is its flexible touch control.

• 👆 Double touch on any earpiece - pause / playback.
• 👇 Triple touch on the right earpiece - the next track.
• 👈 Triple touch on the left earpiece - previous track.
• 📞 Holding on any headphone - reject an incoming call.

You can change these settings through the Mi Earphones app (only available on Android). If the app is not installed automatically, download it from Google Play. In the Touch and Retention menu, you can reassign the actions:

On iOS, you can't reassign controls -- they only work in a standard configuration, and it's also worth considering that sensors can be triggered by random touch (such as walking or running) to reduce the number of false positives:

• 🧴 Wipe your headphones with a dry wipe (sweat or dirt may interfere with sensors).
• 🎧 Check the density of the seating – if the headphones sit too loose, the touches will be recorded more often.

Solving common problems

Even after a successful connection, Redmi Buds 3 users face typical problems, and consider the most common ways to fix them:

• 🔄 Reset the headphone settings and connect again.
• 🔋 Charge the case to 100% – sometimes the battery discharge leads to the disconnection of one earphone.

⚠️ Warning: If after all the manipulations, one earphone still doesn't work, check it on another device. If the problem persists, this may indicate a hardware malfunction (for example, a contact dump inside the case.
